Nu-13: Now beginning termination of subject.
...wanted to surpass her...
I updated my journal today. New things are always very exciting. Our meeting today was about using seithr to create weapons. I have no idea who keeps bringing that up. I hate sitting in that room, with its hard chairs and harder people.
I feel really depressed. It's all because of something someone said to me. I don’t hate Kokonoe. She took good care of Litchi and me, and unlike the others here, I don’t plan to denounce her theory. Her skills and her mind are way beyond what a normal person can hope for. Putting that talent to waste just pisses me off. If I had that skill...Ugh.
I've been getting a lot of stomachaches lately. Every time it happens, she says, “Hang in there,” and cheers me up. I’m grateful for it, but...
Kokonoe hasn't brought in any test animals for a while. I thought she'd just throw this one in Jotunheim, but she told me it was her assistant. I wondered why she chose a monster, but I was afraid I’d get yelled at if I spoke up, so I kept quiet. Still, if that wasn’t bad enough, Kokonoe told me, “He’s inexperienced, so please take care of him,” and made me take the creature along on my investigations. I talked to the creature a little bit, and it doesn’t seem like a bad guy, so that’s something...
I've made a discovery. I was so immersed, I completely lost track of the time. I wrote most of it in my report, but I'll put some of it here too. It's regarding the seithr people often use, but don't understand. Some suggest it's the realization of fairy tales or the result of human sacrifice, but they're all wrong. Seithr is actually a kind of nanomachine.
I'm explain itclearly... Why doesn't anyone get it?
Day 2Why? This is all wrong. We won't make it in time.
every . I want to who it is, no long have mouth. She again. O course.. if don't have face, I make one.
Ahh, itchi, I here.
Calamity Trigger Reconstruction
Summary of the Calamity Trigger Reconstuction from BlazBlue: Continuum Shift Extend.
Having run away from Sector Seven, Arakune found himself within the 13th Hierarchical City of Kagutsuchi, becoming a monster lurking within its sewers. The Novus Orbis Librarium issued a bounty on him, and the monster fed on the kittens of the Kaka in Lost Town, having constant scraps with Taokaka, the clan's guardian.
In the late December of 2199, Arakune was found by Ragna the Bloodedge. The monster sensed the Azure on the man and attacked him, but were interrupted by Litchi, who had become a doctor within the Hierarchical City to protect others from Arakune and to save Roy. Arakune lay on the ground while Ragna and Litchi talked about him before finally escaping. 
It was originally a researcher of Sector Seven, who opened a forbidden door in his zealous search for the truth. It transformed him into an amorphous creature that housed countless insects within its body. It wanders while searching for a "strong life force" that will sustain its existence.

Litchi: I thought you would come here...Arakune:

Litchi: I felt it, too. I was able to sense the Azure. Lao Jiu is doing his best, but I guess it's spreading faster than I anticipated.Arakune:
You c lor... I see u've absorbed too... A sorb... Hahahahaha... HAHAHAHA.
Litchi: I have no regrets. This was the only way for me to stop you. To tap into the power that lies beyond the Boundary...
Arakune: The power of the Boundary is immense, but it is that same power that runs through the Azure. If you have tapped it, then you too will be drawn in... Like us...
Arakune: Litchi, this is a line you must not cross. You can still be saved. Return to Kokonoe. She will know what to do. Damn her, but she is a genius... Kehehe!
Litchi: No, hold on! Don't lose yourself again!Arakune:
Taka... Taka... Takamagahara...! Kiihehehehe! That's how they... Monitor... monitor... monitor us!
Litchi: Ngh... ugghh...Arakune:

Hazama: Whoa, didn't think I'd find you here, buddy...Arakune:
Azure, Azure, Azure... I so bright... It's so rong... The Azure I ve been sea in for all long...
Hazama: *Sigh* Even the power of Izayoi didn't help her... Ah well. I didn't see this coming, but with the Azure this concentrated, I suppose it was only a matter of time.Arakune:
I fe Azure com fro you, o... Az , Azure! Why...w is !? The Azure oire is th rce... life... I infinite!
Hazama: I suppose I should expect this from an incomplete Black Beast... You sure look like a monster, but I guess there's still a brain rattling around in there.Arakune:
The Az ...Yes... I am... self... To ome e Azure...
Hazama: Yes, yes, you're a failure pal. I get it. Still, not just any human could get this degree of transformation. I tip my hat to you. Restriction 666 released! Dimensional interference force field deployed!Arakune:

Hazama: Azure, huh? All right. Lemme show you the -true- power of the Azure! Code S.O.L.! Azure Grimoire, activate!Arakune
Devour, devour, devour, devour, devour! I ill de ur that Azure!
Terumi: Lets play a little, you unfinished little bastard!
Terumi: Well, that was fun... Real good warm-up. Thanks, pal.
Arakune: Guh... gugugugugugu...
Terumi: Well, I'd expect nothing less from an incomplete Black Beast... just as tenacious.
Arakune: I... I'm the... Black Beast?
Terumi: No no no no... What? Didn't you hear me? You're an incomplete copy! You're a good vessel, but if you can't summon the sword, you're just trash.
Arakune: ... Trash...? I am... trash?
Terumi: Yeah, that's right. You're trash, pal, TRASH! All you know is how to devour souls... Though, you're a helluva lot easier to deal with than the REAL deal.
Arakune: You... You... You...! Guhgugugu! The Azure that I want... is right there!
Terumi: All right, playtime's over. The Azure you want so bad is about to wake up!
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
A researcher of Sector Seven. For the sake of surpassing Kokonoe, he touched the Boundary; as a result, he lost his memories and was transformed into an amorphous creature that sought only the Azure. After that, the creature was captured by Relius Clover and modified into a puppet.
Arakune followed Relius around in Ikaruga before being ordered to infiltrate the NOL branch in the 6th Hierarchical City of Yabiko. When he did, he found Noel, who had subconsciously entered the Realm. Arakune assaulted her, but Ragna and Kagura Mutsuki broke down the door and Arakune was forced to fight the Black Knight. He lost and retreated, returning back to Relius, telling him about Noel and Ragna being in the Yabiko branch before being ordered to return to Hazama.
After Relius captured him in Kagutsuchi, Arakune was locked away in a laboratory where he was implemented with an Artificial Causality Phenomenon Weapon. Litchi also worked in this lab and would visit him when she had the time. Before long, Relius sent Arakune to the Ikaruga Region. He was then ordered to attack Bang and Bullet, luring them back to the Grave Marker of Bases. Relius planned to use Arakune as the base for a new Black Beast.
A researcher of magic with a body containing countless insects. Currently living in the sewers beneath Kagutsuchi. In order to maintain its existence, it requires a large amount of vitality, which it obtains through attacking humans and Kaka. Claiming itself as the "Azure Grimoire," he (?) senses the Azure and moves.
Transferred into the Embryo, Arakune strangely became one of the chosen. In the Kaka Village, he found Bullet and fought her until she managed to fend him off.  He later lurked in the sewers of Area 28 until he sensed a piece of the Azure and came across Ragna, whom he assaulted. However, Arakune then sensed Noel, who holds a piece of the true Azure, and stopped in order to hunt down the young woman instead. He attempted to devour her but was stopped by Ragna and was nearly killed by him before Litchi came to his rescue, allowing him some time to flee. 
He ran deeper into the sewers before being chased down by Litchi. When he smelled the scent of the Azure on her, he attacked. However, almost immediately he realized it would overpower him, knowing that the power of the Boundary that she channeled would consume him, and he stopped his attack and fled.  Like the other chosen, Arakune was transported to Ikaruga by Nine the Phantom who told him to kill Izanami to claim his piece of the Azure. Before hunting down Izanami, however, he was discovered by his former colleague Tager, whom he assaulted and forced to retreat.  He found Nu-13 much deeper in Ikaruga and attempted to attack her, but was repelled by Relius Clover, so he fled.  In a possibility created by Phenomenon Intervention, Ragna took Arakune's desire and devoured it. 
Later, Arakune was tracked down by Litchi, Tao, and Bang. He fought the three of them before swallowing Litchi, which allowed her to meet Roy, and then spitting her out again. Arakune desired to become a Black Beast through absorbing nearby seithr, but was stopped by Bang and eventually dissolved into seithr.  It is unknown if Arakune's data was backed up by Es, and he has not been seen since.
