Stage IX: Jin Kisaragi

Mu-12: Detecting Nox-Nyctores-class armament... "Mucro Algesco: Yukianesa." Jin: Noel...Vermillion? Mu-12: ... Jin: Answer me, damn you! Are you Noel Vermillion?! Mu-12: ...Target's combat abilities estimated to be SS-tier. Jin: A Contingency Medium... So in the end, you were nothing but a mindless doll! You useless piece of subhuman garbage! Mu-12: Detecting rising hostility levels from target... Target's threat level now at maximum. Now switching to Battle Mode. Jin: Come on! It's time to put an end to your pathetic existence. Mu-12: The bringer of balance...The power of order...my...enemy! <Mu-12 Victory> Jin: Gah... To be defeated...by...you...! Hazama: Incredible! Nothing less from Kusanagi, I suppose... Or did our friendly neighborhood major just suck too much ass? So much for the power of order, I guess. Mu-12: Target still showing signs of life. Redeploying petals. Hazama: Whoa there Bessy, let's calm down, okay? No need to get yourself all bloody. I might need this dashing fellow for, ah, something else. Besides... Terumi: You're supposed to be kicking the crap out of Amaterasu right now, so what the hell are you doing here?! Mu-12: Understood. Resuming search for Amaterasu.

Stage X: Hakumen

Mu-12: ...Threat levels now at maximum... Hakumen: You have come, then. Mu-12: Analyzing target... Target identified as Sankishin: Susano'o Unit. Hakumen: Child of the Azure. If you can hear my voice, then heed my words... Do you hate this world? Mu-12: Petals deployed... Now switching to Battle Mode. Hakumen: Answer me, Child of the Azure! Mu-12: ...Hate...hate hate hate hate hate hate hate HATE! Annihilate...everything! Everything in this world! Then, I too...will disappear... Hakumen: Hmm. Then you do. Unfortunate. I had hoped you might quell the Azure, but it seems my hopes were misplaced... No matter. It falls to me to see that you are banished from this world. Mu-12: I am Kusanagi...the blade that will bring destruction to all! Hakumen: I am the white void. I shall cleanse this world and return all to nothing. I am Hakumen! The end has come! <Mu-12 Victory> Mu-12: Damage levels...negligible. Resuming attack. Hakumen: Hngh. Impressive, but...what is this power I sense...!? Terumi: Ahahahahahahaha! Oh, Hakumen sweetheart, it looks like you're just having a grand old time! Hakumen: Terumi!? Terumi: Aaaaand scene! Now be a dear, and move along, OK? I've got this stage booked for another act right away. ...No? All right. My good Phantom, if you would... Hakumen: Intervention...? No...no! Magic?! Terumi: Toodles! Oh, just FYI, I took a look-see at all your possiblities, so you can struggle as much as you like, but it's not going to do you any good, I'm afraid... Hakumen: Terumi, you fiend! Terumi: It's a damn shame, dear Hakumen, but it appears you just didn't have the chutzpah to stop the storm that's coming.

Wrath Blade
AD2200/01/07 Terumi: ...Still, if Hakumen was here, then this one's a dud... ...Ah well, life's what you make of it, right? It's time to tie up a few loose ends and move on. Now... Let's get this party started, Ragna the Bloodedge! Show me the power that's gonna change this old world - your continuum shift! Terumi: Ahahahahahahahahahah!

Chrono Phantasma

The Successor of the true Azure and the awakened form of Noel. The ultimate Boundary Interface Prime Field Device. She was the "Sword of the Godslayer Kusanagi," the only one able to destroy the Master Unit that exists in the Boundary, but with the help of Ragna, Noel was able to retain her self-identity. So, to save her best friend, she asks Rachel to teach her how to control this power.

Stage 7: Ragna the Bloodedge

Rachel: I'm impressed you've made it this far... I suppose I should give you my compliments... Mu: ...Thank you...very much... Rachel: Hm, you seem a little down... What's the matter? Mu: Ah... Well, no... I understand that this is the "Imagined Landscape" that you've created for me, Miss Rachel...it's just... I find it difficult to use this power on...well...anyone. Rachel: Complaining already? I must say, I'm a little disappointed. Have you not already made up your mind you were going to fight? Mu: My desire to protect everyone has not changed, and I am grateful to you, Miss Rachel... But...I don't want to use this power if it's possible. Rachel: You mean to tell me that was the extent of your conviction? Mu: ...I'm sorry. Rachel: *Sigh* I see... Perhaps we need to mix things up a little...as they say. Ragna: Owww! Goddammit, where the hell am– Noel?! Mu: Huh? Ragna...? Ragna: What the hell are you wearing...?! You idiot... Rachel: Just so you know, Noel...he's the "real" Ragna. Mu: Huh? Huuuuh!? R-Ragna...don't... Don't look at me! Ragna: Aren't you supposed to be...Kusanagi?! Hey Rabbit, is this your doing?! I think you owe me an explanation! Rachel: Oh, you and intelligence never seem to get along, now do they? *Ahem* "Oh Madam Rachel, could you please enlighten this dull mind of mine with what might be going on about me?" Ragna: ...I'm seriously gonna make you cry. Rachel: No matter. Dealing with idiots like you really isn't my forte. Why don't you try and fight Noel right here. Noel...you know what to do, right? Ragna: Rabbit...what the hell are you– Mu: Please, Ragna...u-um...I... After you saved me, I haven't had the chance to thank you properly, but...but... What I'm trying to say is... I want to become strong, like you, Ragna! So...could you please fight me? Ragna: Okay, okay, I get it guys. I just have to fight you, right? Is that what you want? So please, just stop looking at me with those watery puppy-dog eyes, yeah? Mu: Th-Thank you very much! <Mu Victory> Mu: U-Um...please don't stare at me so much... Ragna: Huh? O-Oh, right... Sorry about that. Hey wait a sec...how was I supposed to fight you with my eyes shut!? Hey Rabbit, I fought her. You happy? Now about that explanation...! Actually, just let me go home! Rachel: ...This is really starting to irritate me... Ragna: Say what?! Rachel: Never mind... Let's see, there really wasn't any purpose to this battle... I just wanted to see Noel's determination, that's all. The reason I summoned you? Well...it seemed like fun... That's all, really. Mu: Wh-Whaa...? Rachel: ...What are you all mad about? Oh, that's right. Noel... I was actually looking for you– Mu: Eek! Rachel: Phenomena intervention?

Stage 8: Nu-13

Mu: Huh? Where am...? Ragna? Rachel...? Hazama: Hey little puppet. Long time no see. Mu: ?! Hazama?! Hazama: Damn...this sensation... Stupid vampire, always meddling in my affairs... Mu: What are you trying to do, Hazama...? Hazama: Shut up, I don't need to talk to you, you damn doll. Hey, 13, we don't have much time. Make it quick. Nu: Roger. Mu: Y-You're...! This strange feeling...are you the real one? Nu: Target determined to be phenomena variant... Code...unknown. Murakumo unit...activate. I...I can't run...I've already decided, I'm not going to run! I have to fight...to protect everyone, I have to stand up against you! Mu: Summoning Lux Sanctus! Nu: Commencing termination. Mu: Murakumo unit...activate!

AD2200/02/03 Hazama: You idiot...how can you screw this up? 13, stand down. Nu: Ro...ger... Mu: I won...right? Rachel: Noel. Noel! Are you alright? Mu: Oh, Miss Rachel... Yes, I'm fine! Rachel: ...You do seem to be doing all right. Well, first things first, we must get away from here. ...I understand now. I have an idea what Terumi was after, so... Rachel: Noel, you should go to Kokonoe's place once– Are you even listening to me? Mu: Huh? Oh, right... I should go to Kokonoe's place, right? Rachel: What a refreshed expression you've got. Did something good happen to you? Mu: ...I'm not sure exactly how to explain it, but... I think I– I think I'm finally beginning to understand. What it means to be "strong". Although honestly...it's like trying to grab fog... Rachel: ...Hm. Well, do your best with that. Mu: Thank you very much! A-And, um... Miss Rachel...? Rachel: Yes? Mu: At first I was afraid of you because you seemed like...well, a scary person, but... You're actually quite nice when I get to know you. I think I really like you, Miss Rachel! Rachel: I know... Not that it makes me any happier. Gii: Noel... Nago: I think you're just misunders– Nago & Gii: B'huragh! Rachel: I suppose we can just say "you owe me one". Until next time, Noel. Mu: Miss Rachel...thank you very much. I'm gonna do my best.

Story Mode

When Noel created the Realm, an imaginary space out of her own subconscious, Rachel helped the girl try to accept herself. This led to Noel coming face-to-face with a reflection of her soul that she did not want to initially accept or even acknowledge – Mu. Noel won her battle and, with Rachel's encouragement, accepted her power, gaining access to Mu's form. This was tested against Nu-13 shortly afterwards, leading to the first known clash between two wielders of the Lux Sanctus: Murakumo. The Realm collapsed shortly afterwards, but Mu's power was now accessible by Noel.

Noel activated Murakumo again, relying on Mu's power to help her battle against Ragna as he was sent berserk by Izanami. She failed to stop him and he disappeared after gravely injuring Jin.

Central Fiction

The Successor of the Azure and the 12th Prime Field Device, as well as the true form of Noel Vermillion. She awoke in Kagutsuchi as the "enemy of the world," and was attacked by her friends one after the other. In order to discover the true meaning behind this phenomenon, she begins to act.

Act 1: Phantom of Labyrinth

Stage 3: Makoto Nanaya

Mu: This place is the same, too... It's like the place Miss Rachel took me to... But why does it feel so much larger...? Who could possibly do such a thing...? Huh? Is that...!? It's you, Makoto! Eeek! Wh-What's going on Makoto? Why would you...? Makoto: Shut up! This is all YOUR fault! Mu: ...Huh? Makoto: I'm going to crush you...for everyone's sake! <Mu Victory> Makoto: Grr... This is the best I can do alone...? Mu: I-I'm sorry, Makoto. Are you alrig-- Makoto: Stay away from me, you witch! Mu: ...!? Makoto: Why don't you kill me already... like you've killed... everyone... else... Mu: ... Could this be Yuuki Terumi's doing...? It must be. What shall I do!? I can't escape this place on my own... I-I need to find clues first. Perhaps Miss Rachel is also here. I'm sorry, Makoto...!

Stage 6: Izayoi

Izayoi: I've finally found you, Noel. I've searched everywhere. Mu: Tsubaki!? No... don't tell me you're... Izayoi: Give up... the power of the God Slayer you possess. I shall seal it once and for all. Mu: As I thought... It wasn't just Makoto... but you, too, Tsubaki? Your taste disgusts me, Terumi... Izayoi: Enough mumbling and face me! Do you realize what you've done!? How much misfortune must you bring to mankind until you're satisfied!? Mu: ...!? What have you done to Tsubaki. I'll never forgive you! Izayoi: You're making no sense at all... but as an old friend, I shall end you, personally! <Mu Victory> Izayoi: Guah... how is this... possib... Mu: *Pant pant* That was just like... the real Tsubaki. And what is this sensation...? Is it because of this space...? No, something in this world is... Maybe I can find something if I go to the cauldron. I need to hurry...!

Stage 7: Kagura Mutsuki

Mu: ...Kagura? Kagura: Hey, I've been waiting for you, Noel. Mu: But... what are you doing here? Kagura: I picked up wind that you would go for the cauldron. So I've been waiting. Mu: ...Which means, you're after me, too, Kagura? Kagura: Whoa, whoa... Don't tell me you've forgotten what you've done. You know why I'm here. Mu: ... Kagura: But I suppose some responsibility falls on me, too. I should've noticed, being this close. Which is why I need to put an end to my own mistake. Mu: Wha...!? <Mu Victory> Mu: Please, Kagura... Please stop this...! Kagura: Dammit. That didn't go as planned... Power of the God Slayer, huh? Mu: I don't want to fight you, Kagura... Please, tell me what happened! Kagura: What!? Noel... Are you kidding me!? Mu: I have no memories of THIS world. Tell me, what have I done to make you hate me so much!? Kagura: Don't mess with me... after what you've done... Kagura: Don't you know...? You're now the most wanted SS-ranked criminal. Mu: ...!? Kagura: You've defeated both Jin Kisaragi and Ragna the Bloodedge... And you've destroyed most of the Hierarchical Cities. Alone. Who would believe you? Mu: No... I did what? To Ragna and Major Kisaragi...? Kagura: Cut it with the act. Kagura: You're the very symbol of evil in this world. Mu: I'm the symbol of...? Kagura: How many innocent lives died because of you...? What would Jinny and Rachel say if they saw you now... Mu: Miss Rachel...? That's right, Kagura--! Do you know where I can find Miss Rachel!? I'm sure that she could... She could figure out what's going on in this space! Kagura: What are you saying...? Don't you remember...? She was the first one you killed... Mu: No... it can't be. I-I would never do that to Miss Rach... ???: Understand now? Your existence brings despair to people. Mu: Who are you!?

Stage 8: Nine the Phantom

Nine: We finally get to meet, Noel Vermillion. I am Nine... and I believe this is the first time we've met. Mu: Nine...of the Six Heroes!? How do you know about me...? Nine: I know all about you, and I've wanted to meet you, as well. I've been watching you from here. Mu: Then you mean... you created this space...? Nine: No, this world simply isn't some "space." It is one "reality" conceived by you. Make sense? Mu: Conceived by...? But that's impossible...! Nine: I think deep down you already knew... about the oddities of this world. That this world is real. Mu: I-I wouldn't...! Nine: Never mind... In that case, you will see it for yourself. Along with the despair of this world. <Mu Victory> Mu: Kah... The strength of the Six Heroes...!? Nine: Unbelievable... You really don't understand what's happening? Accept it. You've been denied by your very self. Inside the Embryo. Mu: Embryo...? Nine: Heh heh... the world you wanted to create has no place for you. Look around you! The proof is everywhere. Mu: Stop saying that! I don't believe it's true! I won't! Nine: Well, then suit yourself. But remember what I tell you, if you change your mind. If you choose to deny this world... Nine: Before the Day of Reckoning, the Imperator... No-- Izanami must be defeated. By your hands. That is the only way for you to escape... ...This world. AD2199/XX/XX μ-No.12- ACT1 END to be continued

Act 2: Nightmare Memory

Stage 3: Hibiki Kohaku

Mu: Somewhere quiet... I think this should do the trick...? --!? Hibiki: I've searched everywhere for you, Miss Noel. Mu: H-Hibiki!? Wh-What could you mean--!? Hibiki: You're going to play dumb? Forget the countless acts against the NOL, you dared to harm Master Kagura and fled the scene... YOU are the reason this town's artificial climate has ceased to function. Don't for a moment think we don't know you destroyed the NOL satellite branch. Mu: What are you saying, Hibiki? You're all wrong, though! I didn't do anything! Hibiki: Didn't do anything...? Then why is the whole world searching for you? Deny it as much as you'd like, but the truth cannot be changed. It's time to face the music and realize you're an enemy of the world. Mu: No...! <Mu Victory> Hibiki: It would seem... I am still far too weak. Mu: Hibiki... Could I really have created this world like they say? I need to find Noel Vermillion right away!

Stage 6: Valkenhayn R. Hellsing

Valkenhayn: I've finally found you, you witch! Mu: ...!? M-Mister Valkenhayn? Valkenhayn: I shall see to it that my late master has her retribution. Mu: Please, listen to me. I... I would never hurt Miss Rachel... Valkenhayn: Silence! I shall make sure that Milady's name is never uttered from the lips of a witch... Your sins shall be met with death! <Mu Victory> Valkenhayn: G'ah... Forgive me, Madam Rachel... Mu: ...! Valkenhayn: Finish me, you witch! But remember this... If all that's left of me are my soul and spirit... I will not stop. Hide if you dare, but I will chase you to the ends of the earth! You have not seen the last of me, Noel Vermillion...! Mu: I-I'm so sorry, Mister Valkenhayn...!

Stage 7: Hakumen

Mu: ... Not here either... Where could you be, Noel? --!? Who's there!? Hakumen: ... Mu: You're... Hakumen. One of the Six Heroes? Are you trying to kill me, too? Hakumen: ...Indubitably. Noel Vermillion, I've come to destroy you! Mu: Because I am the source of evil...in this world? Hakumen: Evil, you are not... You are the very source of this distorted world. Mu: Distorted...? P-Please, wait. Could it be that you're-- Hakumen: Enough banter... En garde, girl of the Azure. <Mu Victory> Mu: *Pant pant* No... I can't hold on any longer... Hakumen: ... Mu: ...Huh? Hakumen: Hmph... Slaughtering you in your current state will do nothing. It would seem I must seek an alternative path. Your life has been spared, Child of the Azure. Mu: Wait! What did you mean when you said I was the source... Hakumen: ...I believe you already know the answer to that question. Nine: One of the truths created by Noel Vermillion... Mu: Then this world is... ...!? No... This sensation, it can't be--!?

Stage 8: Izanami

Mu: The Imperator...!? You mean you were in this world, too...? Izanami: Noel Vermillion... Sword of the Godslayer. I've grown tired of seeing your face everywhere I look. Mu: ...! I don't know what you're up to, but... I'm putting an end to you! Izanami: Foolish. The world has rejected you, so you point your blade at me in hopes you can escape your fate!? Mu: No! I'm not trying to run away from anything! Izanami: Don't make me laugh... Hard to believe those words from someone who denied her own existence. ...Well then, let me show you the world you yourself wished to create! Witness it with thine own eyes! <Mu Victory> Mu: --Huh? Mu: Did I... win? And what's this...? Izanami: That is a fragment of the Azure. Now, pick it up. Mu: ...! Mu: -- This is where you've been hiding... Noel: ...Stay away! Mu: Why? I am you... You would deny my very existence? Noel: No... You're nothing like me. So stay away! Mu: Wait. At least tell me the reason. Why would you-- Huh? You're... ...Who? Mu: I hate it... I hate... hate... HATE it all! It's all her fault... This power. That woman... I don't need anything anymore... I don't need this world... anymore! Everything should burn to the ground...! Mu: --Huh? No... You mean, I did this...? I-I would never... do such a thing! This is a lie...! Izanami: What you see is all true. Have I not told you? No matter what you do, the truth you yourself have denied cannot be changed. Even with the power of the Azure... nothing will change. We are, after all, talking about the single truth. Mu: Ah... Ahh...! Izanami: Heh heh heh... That's right. Hate the world that denied you. Unleash your fury for Noel Vermillion. That woman pinned all her sins upon you... ...And ran away. You're not the one source of phenomena in this world... She is! Mu: Nooooooooo! AD2200/XX/XX μ-No.12- ACT2 END to be continued

Act 3: The Replacement Blue

Stage 3: Makoto Nanaya

Makoto: Finally, I found you... This is where you've been hiding, Noellers? Mu: Makoto! Thank goodness, you were alright. Makoto: ... Mu: ...? What's the matter? Makoto: There's something I need to confirm, Noel. Mu: Huh...? Makoto: Is it true that this world is built upon your wishes, Noel? Mu: ...I don't know. But even if that were the case, you have to understand that was not my intent-- Makoto: I'm sorry. Whether or not you intended it, if that's the truth, then "we" need to defeat you. Mu: Makoto...? Wh-What are you saying...!? Wha--!? Makoto: This is the first time we've fought each other all-out. Get ready, Noel! Mu: K'uh...!? <Mu Victory> Makoto: Damn... This is the sword of the Godslayer... Mu: Makoto... Why are you doing this...? Is this all really "Noel's" fault, like Izanami said...? That's why everyone's looking for me...? No, that can't be it... I need to focus. That's what Izanami wants me to think. I need to find Noel to be sure... Where are you?

Stage 6: Hibiki Kohaku

Hibiki: You are... Miss Noel? Mu: H-Hibiki! Perfect timing. I need to speak with Kagura-- Eek!? Wh-What was that for!? Hibiki: The sheer nerve you must have to walk through Yabiko as though nothing happened... Astonishing. Miss Noel. I'm sure by now you are aware of what you're doing to this world. Mu: Don't tell me... even you're after the Azure... to make your wish come true!? Hibiki: Please do not confuse me with yourself... I'm not here to create a world of self-fulfilling interests. This is for the sake of Lord Kagura's new world. I'm afraid that for his bloodless revolution to occur... Your blood alone must be spilled. Mu: Stop this Hibiki...! Please, stop--! <Mu Victory> Hibiki: ...! Mu: A-Are you alright? Hibiki: Stay away from me! Mu: ...!? Hibiki: I don't want your kindness... Not now. Mu: ... Hibiki: Remember this... I'm not the only one who is after your life. All the sacrifices the others have made...outweighs your life many fold. Mu: The others...?

Stage 7: Iron Tager

Mu: Ibukido. This is the last place I've detected Noel's readings... Don't tell me, she's there!? Tager: ...Finally. Mu: Mister Tager... I see. What Hibiki said was true... He was talking about Professor Kokonoe. Kokonoe: I won't ask for your forgiveness... But our options are dwindling by the minute. By your hands, no less... Heh, how's that for irony? Mu: You have the wrong person! I've also been rejected by her... Noel. Kokonoe: ...What!? Don't tell me you're...only half!? She actually separated herself from the Sword of the Godslayer...? Why? No, wait...! Hey. Has your memory been altered since you woke up in the Embryo? Mu: Huh...? No, I don't think anything like that happened to me... Kokonoe: Impossible... She actually separated her memories, too...? Something doesn't add up... Tager, bring her in. I don't care if you have to use force. Tager: ...Roger that. You heard the lady. Don't hold this one against me, Noel Vermillion. <Mu Victory> Tager: G'rr... I had a feeling you wouldn't come easy. Sorry, Kokonoe... Kokonoe: You fool... You've let your guard down thinking she was Noel. Mu: Umm... I'm sorry, Professor. But I can't be caught just yet... I need to find Noel myself. Kokonoe: What!? Noel Vermillion is in Ibukido!? Then Noe-- err, Mu-12. What do you intend to do when you find her? Mu: ...I don't know. But I think I'll find out once I see her. That's why I must press on...!

Stage 8: Noel Vermillion

Noel: Ah... Mu: Finally, we meet. Noel Vermillion. Noel: Why me...? Who are you...? What's going on in this world...!? Mu: Unlike the others, your memories are not altered by the state of the Embryo. You've separated yourself from me of your own volition... Noel: What... What are you saying...!? Mu: Please, lend me your strength. We're the only ones who can fix this distorted world! And I want to know the truth...of who I am. So, please! Noel: No--! Mu: ...Huh? Noel: Nooo! Stay away! Mu: C-Calm down! I'm not your enemy! I'm your other half! <Mu Victory> Noel: *Sob sob* Why...why is everyone being so mean to me...? Mu: Don't worry, I won't harm you. So, please tell me... Who are you, really? Noel: The "real" me...? Ah... Ahhhhh no! That's not true... I don't want to remember...! Mu: Wh-What's going on!? What happened to you!? Noel: I'm afraid... I'm afraid of this power. I don't want it...! Mu: Noel! Get a hold of yourself! ???: Finally, you remember... Who you are, and from whence you came. Mu: Wha--!? Mu: Izanami...the Master Unit...!? Izanami: Sword of the Godslayer... I had expected the chosen to dispose of the both of you by now, yet...here we are. Mu: ...! You're the one who turned everyone against us. Izanami: Spare me your complaints... The chosen were acting on their own volition, not mine. Mu: You're twisting the truth...! Izanami: Enough. I'm not here to speak with you... I'm interested in, her. Mu: Huh...? Noel: M-Me...!? Izanami: That's right. I've come to return you to your casket. The one who made first contact with the gods... ...The one who witnessed genesis. AD2200/XX/XX μ-No.12- ACT3 END to be continued

Story Mode

During the confrontation with Ragna, Mu was split from Noel's soul and became her own separate entity, but maintained Noel's memories and personality. Mu-12 was also absorbed into the Embryo, but was sent to a different world from the others. In this reality, she had murdered many people, including her friends. She discovered Makoto while still unaware of her circumstances and was attacked by her. She fought back and knocked her former friend down.

Inside the NOL branch of Kagutsuchi, she found Tsubaki, who turned her blade against the Godslayer and asked if it was fun to kill so many people and take their futures away from them. Tsubaki transformed into Izayoi, and the pair fought until a phenomenon intervention took Izayoi away. Mu began to despair over her circumstances, but resolved to find the Cauldron. Kagura blocked her way, his words making her lose control. She fell into a depression and stopped acting like Noel and more like the original Mu-12. Once she killed the illusion of Kagura, the cauldron opened itself up.

Inside the cauldron, Mu discovered Es guarding the Forbidden Gate -Altar-. The two fought briefly before Mu lost to Es, and was sent back to the original, real world. There, the real Hazama found her and managed to manipulate her into a robotic trance, whereupon he ordered her to kill the real Ragna. She complied, but Ragna freed her from her trance, and she was able to direct him out of the phenomenon event and back to his original reality. Mu attempted to follow but couldn't, and asked Ragna to bring Noel to a cauldron so she could fuse with her again. Ragna fulfilled his promise and brought Noel to a cauldron, but Noel rejected Mu, forcing Mu to wait until her other half was able to accept her.

Fusing together with Izanami to regain all of Saya's soul

Mu was finally accepted by Noel later when the latter used the Azure Grimoire as a cauldron. With this, Mu finally reunited with the other half of her soul. Noel would later use Mu's power to fully absorb Izanami and Saya into herself, and become the complete whole of Saya.
