Platinum the Trinity/Biography
Owner of the Nox Nyctores Muchorin. The two hate conflict of any sort and used to live quietly in the ruins of Ibukido, which was part of the former Ikaruga Federation, in order to monitor a "certain something." However, due to a request from Jubei, to whom they owe their lives, they travel to the Thirteen Hierarchical City Kagutsuchi.
Transcript of Platinum's Continuum Shift Extend arcade.
|Stage IV: Ragna the Bloodedge|
Luna: Ugh...! Where in the hell are you? Luna's so... hungry...!
Sena: I feel your pain... Right now, I'm just exhausted and about to drop dead from starva- Wait, Isn't that...?
Luna: Ah! It's him! Ragna the Bloodedge!
Sena: Y-you're right.Let's see if he'll buy us something to eat...
Luna: wha-? Luna'll pass on that... If you want to hit him up for free eats, then go nuts, Sena!
Sena: Eh?! Luna, how could you be so cold...?
Ragna: ...Huh? Who in the hell are you?!
Sena: ugh... My stomach... I... I'm... so... hungry...
Ragna: Is that so? Well, it sucks to be you.
Sena: Ugh, you're so mean... so cruel how can you call yourself a human being? I'll curse you... I'll haunt you until you die lie cold and dead in your grave.
Ragna: whoa, no need curse me, you know?! We definitely wouldn't want that... Not at all...
Sena: B-but I...
Ragna: All right spill it. If you were starving so badly you wouldn't have the energy to radiate the levels of murderous rage like... you... are now.
Sena: ...Huh? So you figured me out...? What gave me away, I wonder...?
Ragna: That thing you've got. That's a Nox Nyctores, isn't it? What in the hell are you plotting?!
Sena: Plotting...? You make it sound so...ominous.
Luna: ARRGH! I can't take this crap anymore! Luna is going to rip this idiot a new one and turn in what's left for that obscenely huge bounty!
Ragna: Dear god, why me?! Why do I always seem to attract the who's who of mental illness...?
Ragna: Gah...! How could this... Possibly be happening to me...?
Luna: Damn... Luna's stuffed. I mean, not only did I get to gorge myself on Ragna's dime, but Luna also kicked the crap out of him as well!
Sena: I must agree that the meal was very satisfying... Well Ragna, you're picking up the check, right? Um... I guess we should thank you...
Ragna: ...What in the-?! H-hey, you...guys! Wait up! Goddamn it, that little brat got me good. I'd kill to get my hands on whoever taught her.. him.. them how to scam people like that!
|Stage VIII: Taokaka|
Sena: Nope... He doesn't seem to be here, either.
Luna: Hey! Let's go ask that person over there!
Sena: Ah, Hold on for a second! Umm... I have a really bad feeling about this...
Taokaka: Meow?! That's a ginormous bell you have there... Anyway, you wanted Tao for something?
Luna: Umm... Do you know someone called Bang Sissy-gami?
Taokaka: Come again? Beat up on a sissy-mary? ...Tao's not sure if she wants to do that, but i do know a scruffy man!
Luna: Really?! It's about damn time we got a little luck! So, where is this scruffy-looking nerf herder?
Taokaka: What, tell you for free? The world is governed by the law... of equi...libri...um...! Even Tao is cognizant of this principle!
Luna: Wh-whoa, where in the heck did that come from? I wonder if she even understands what she just said...
Taokaka: I want that giant bell of yours! You can't hide anything from Tao! You're hiding a huge meat bun in there, aren't you?!
Luna: Uh... Come again?
Sena: I really don't like where this seems to be heading...
Taokaka: There is but one universal truth! But will that truth be Tao receiving a tasty meat bun, or will she spill the beans about scruffy man?!
Taokaka: Nyaaa...! Tao lost...!
Luna: Now, tell us everything you know about this scruffy guy... Bang Something-or-other!
Taokaka: Well, scruffy man is just scruffy. I mean, really, REALLY scruffy!
Taokaka: Umm.. Let me see... Well, his scruffiness makes the ground beneath Kagutsuchi tremble. It pierces the very heavens...! He is what it means to be scruffy...
Sena: L-Luna... This guy seems really super amazing...
Luna: Y-yeah, Luna's thinking we'd be better off not finding him at all.
|Stage IX: Bang Shishigami|
Luna: Oh come on! Don't tell me this... is the guy... Huh?
Sena: Eh..? Why do i feel so... Light... Headed...?
Bang: Wh-what's this?! Stay with me, little friends! Do not go towards the light!
Trinity: ... You needn't worry about them. My name is Platinum the Trinity. There are a number of very important things I must pass on to you.
Bang: Ah, so it was your aura that I sensed! Very well, Lady Platinum, What do you require of Bang Shishigami? Protection? Tutelage in the ninja arts?
Trinity: The... True reason behind the fall of Ikaruga... And also... The power entrusted to you by Lord Tenjou...
Bang: What?! What do your words mean?! Speak, mysterious visitor!
Trinity: ...But before i speak of these things, I must be sure that you have the strength to bear the burden that the truth will place upon you!
Bang: *Pant* *Pant* Now.. I demand you... *wheeze* Explain your... true motives...! *Pant* *Pant*
Trinity: I see.. I understand how... you are able to...
Bang: Lady... Platinum, was it? Is something wrong? You look pale...
Trinity: As of now... My existence.. is tenuous.. at best... But... there is much... I have to...
Bang: Lady Platinum? Lady Platinuuuuuuuuuuuuuuuuuum!
Hazama: Oh ho... Well, that's an interesting possibility isn't it...
Bang: Another strange visitor?!
|Stage X: Hazama|
Hazama: Ah, everyone's favorite Nox Nyctores, the Arma Reboare: Muchourin. You're a little...uh...cuter than last time, "Platinum the Trinity."
Bang: Then you must be the villain Hazama...
Hazama: Oh! My apologies, I nearly forgot about you. You'll really have to excuse me, but I don't really...Need you anymore now, you know? If you could just run along...
Bang: Why you! How dare you- Gyaaah!
<Bang is teleported away>
Hazama: Phantom, you are indispensable. Now we should be able to talk without any more distractions- Oh? Did we wake up one of your other, ah, yous?
Sena: Ah, Luna, are you alright?
Luna: I think so. I-i'm not sure what's going on right now, but... who in the hell is THAT guy?!
Sena: I'm fairly certain that he is the one we were warned about.
Luna: So you're that twisted son of a bitch, huh?!
Hazama: I may be a twisted son of a bitch, young lady, but that doesn't mean I don't have feelings!
Luna: Shove it, freak! Luna is going to kick the holy crap out of you!
Hazama: Oh-ho! Looks like someone needs to learn to respect her elders! I think a spanking is in order! Restriction 666 released! Dimensional interface forcefield deployed... How'd you like a special treat? Well, you're getting it anyway! Let me show you the TRUE power of the Azure! Code: S.O.L..! Azure Grimoire...activate!
Sena: Luna, it really is that person...!
Luna: Yeah, it was just as Master Jubei said!
Hazama: Ahahahahahahaha! Oh, I thought I felt that old bastard's paws in this, and sure enough, he's pullin' the strings! Little guy sure does keep me entertained, though!
|lies and regret|
Terumi: Oh, so you've got a handle on using the Muchorin with two personalities, huh? Well... *Clap* *Clap*
Luna: Ugh.. Damn it...!
Sena: *Pant* *Pant* He's..really...strong...
Terumi: Wellllll, as much fun as this is...Shall we?
Luna: Wh-What in the hell?! What's with all of these waves?!
Sena: I...I recognize this. I can feel it within my memories. But it's like someone is telling me not to look for the answers. Who... who are you..?
Terumi: Oh for goodness sake! Just give up, Trinity! It's cute that you're trying, it really is, but you LOST! L. O. S. T. Why drag it out?
Luna: What in the hell... is he going on about?
Terumi: Go on, "Platinum the Trinity!" You remember the good old days? Hm? Remember the day when all your friends disappeared?
Luna: Ugh... my.. my head, it hurts!
Terumi: Oh, it was delightful! I remember it very well. The world's "strongest" witch bowed to me! And do you remember why? Hm? Because of YOU, Trinity!
Trinity: Yuuki... Terumi!
Terumi: Mmmm, yes! It just makes me stronger, you know! And then... Then I bring the despair!
Terumi: Now... Murakumo...activate! This world is nothing but lies! LIES!
Terumi: Lemme show you what I like to call the truth! The truth called "despair"! In the name of Susanno'o, I command you! Murakumo, AWAKEN!
Terumi: Behold the sword of the god-slayer, KUSANAGI!
Terumi: Let all that lies fall before your divine blade!
Terumi: Gaahahahaha! Finally, I've got the true successor to the Azure! Try and stop me NOW, Master Unit
Terumi: Now I've learned of another possibility! Good moves out there, bud! But I really owe you thanks. All of the possibilities of this world... the Continuum Shift, I will make it MINE! Hyaaahahahahaha!
A girl inside whom the souls of the rash and headstrong girl "Luna," mild and relaxed boy "Sena," and one of the Six Heroes "Trinity Glassfille" coexist. She takes the Nox Nyctores "Arma Reboare: Muchorin" in hand and wanders Ikaruga to defeat Terumi for their beloved Jubei's sake. 
For a month, Platinum had been travelling with Bang to return to Ikaruga. Trinity had sensed the use of sorcery nearby, worrying Bang.  The two of them soon arrived in the 8th Hierarchical City of Wadatsumi, finding Carl Clover. The two introduced themselves to one another, although Luna accidentally called the Deus Machina: Nirvana a doll, leading to Carl pushing aside. The group then disbanded with Luna claiming that she wanted to go the 7th Hierarchical City of Kazamotsu.
Trinity took over Platinum's body and fatally attacked Hazama. The man retaliated and stabbed her before dragging off the side of the Monolith they were standing on. Trinity, Luna, Sena, and Hazama all fell into a nearby lake, presumed deceased.
When Bang and Platinum arrived in the 7th Hierarchical City of Wadatsumi, Luna was shocked at Bang's seriousness. Although both Luna and Sena wanted to cheer him up, they had no idea how to, and decided to leave to continue to another Hierarchical City. Little did they know that Bang had sent one of his ninja to watch over them as they travelled as he feared they would not be safe. 
She was later taken by Valkenhayn R. Hellsing into the Alucard Castle, but when Luna awoke, she found Rachel Alucard, Nago, and Gii. She quickly set her sights on the three of them, throwing a massive temper tantrum. Luna and Sena were easily bested by Rachel, and their consciousness slipped from them as Trinity took over.
Platinum promised Jubei to defeat Terumi, but Luna and Sena did little battling as Trinity took over the body when they encountered him. In truth, this was not Terumi but a shadow of him created by Phantom's pure hatred.
The rash and headstrong girl "Luna," the mild and relaxed boy "Sena." The two coexist in one body, and together possess the Nox Nyctores "Arma Reboare: Muchourin." In the land of Kagutsuchi that Jubei had been searching for, they realize that something about themselves has begun to change. 
Platinum became one of the chosen and was absorbed into the Embryo, and their memories were altered accordingly. Trinity left Platinum, inhabiting multiple Nox Nyctores before she found her way to Jin Kisaragi's Yukianesa. Without Trinity, and in an unstable location like the Embryo, Platinum's existence destabilized and began to fluctuate between existing and not. They found themselves in Bascule, and bumped into Bullet, who was unable to recognise them.
Nine the Phantom teleported Platinum to Ikaruga and told them to kill Izanami for their wishes to come true by claiming their piece of the Azure. They were attacked by Nu, but managed to escape after their unstable existence made them invisible to Nu's scanners. Luna, however, began to forget Sena's name and vice versa, and their bodies became transparent before briefly returning to normal.
Jin Kisaragi and Trinity eventually found them, and using the Power of Order, Jin was able to stop Luna and Sena from disappearing. Using Muchourin, Platinum materialised Trinity and they formally met for the first time.  Trinity, Jin, and Platinum teamed up to break into a Sector Seven facility to retrieve data on Platinum's body. Here, Trinity revealed to them that Platinum's body was originally meant for Trinity herself, but she decided against using it. They then escaped with the data.
Later, Platinum's body was modified by Trinity and Carl to better suit their needs and to prevent them from disappearing. After the maintenance, the trio parted ways with Carl and were found by Jubei, who warned them of the eleventh Nox Nyctores, Corpus Sepulcro: Requiem.  Luna and Sena were soon dropped off in the Kaka Village and were ordered to materialize the Hihiirokane using Jubei's Sekkigan, the eye of his brother Tomonori. Although worried for Jubei since he had a serious wound, they pushed on to create the blade as they did not want to let him down.  They eventually completed their task, giving it to Hakumen when he came for it, learning that Jubei could not retrieve it as he was locked in space-time. 
Platinum eventually dissolved into seithr, her data backed up by Es. She was reborn in the new world created by Ragna where she was escorted by Mai and Kajun to Litchi's clinic – she met Linhua, and it's presumed that she came under Litchi's care.
