Thread

Thread is a Level 3 Akuma who was personally chosen by the Noah Tyki Mikk to kill Allen Walker after his own failure to do so.

Appearance
Thread has light gray armor in a similar style which all Level 3 possess. Aside from his coloring and the slightly different style of armor, there is little difference between his and other Level 3, though he does have distinct, canister-like growths on the outer sides of his hands that produce his Dark Matter threads.

Personality
Like all sentient Akuma, Thread is bloodthirsty and sadistic, using the particularly slow death his Dark Matter abilities allow him to cause to torment his victims. As he died, though, he helped Allen out by telling him how to use the Ark Gate to get to Edo, saying when asked that he was feeling "really good".

The soul within Thread was deteriorated beyond recogniton, left with only the thought that it wanted to be loved and saved and knowing by instinct that Allen existed to save it.

Edo and Asian Branch arc
Thread was sent personally by Tyki Mikk to locate Allen and bring him back, though Thread noted as he decided to kill Allen that he had never been ordered to bring him back alive.

As Allen Walker was training to try to regain his Innocence, and while the rest of Cross Marian's unit fought in Edo, Japan, Thread was sent to the Black Order Asian Branch via Noah's Ark by Tyki Mikk. After arriving in front of the branch, Thread used the Ark again to get passed For's barrier, opening a Gate directly through her body.

When For tells Allen to run (though Allen refuses), Thread responds by shooting one of his threads through Allen's chest, telling Allen he cannot allow him to escape before explaining that his Dark Matter allows him to deconstruct and absorb matter. Thread then torments Allen, causing him extreme pain and saying that he was never ordered to bring Allen back alive. Just then, Bak Chang intervenes, using his family sorcery to activate the pillars in the room and immobilze Thread while For frees herself and uses her arm blades to cut the thread running through Allen's chest.

As the building evacuates, For stays behind and disguises herself as Allen to distract Thread, who falls for the trick. Thread fights and seriously damages For, not noticing that she isn't Allen and wondering why the Noah would allow him to use Noah's Ark to hunt down and fight someone so "disappointing." When For answers that she's "just a boy," Thread tells her to die while shooting one of his threads through her forehead, making her already damaged body shatter further. Just then, the real Allen arrives and lands on Thread's back, and when Thread turns to him and asks what he is, Allen answers that he is an Exorcist.

For resumes her regular form and Thread realizes that the newly arrived Allen is his real target, asking if Allen is strong. Using his Eye, Allen sees Thread's badly deteriorated human soul, which calls out for him to love and help it and asks Allen if he doesn't exist for them (the Akuma). Allen answers "that's right," making Thread think that Allen had answered his question rather than the question of his soul, and then he and Thread begin to fight, Thread using his ability to form a blade and stabbing at Allen repeatedly while telling him to disappear. When Allen lands too hard one one of his feet, his body cracking and starting to shatter, Thread calls him a fool while summoning another blade and slashing Allen and pushing him down into the water below.

Bak tries to help Allen by using his God Seal to form a giant stone hand, but Thread cuts the hand in half with one finger before turning on Bak and shooting both him and For, who Bak is holding, with his threads.

Suddenly, Allen, spurred on as he remembers his purpose, manages to use his Innocence to reach out and protect Bak and For, Allen speaking out and saying that his left hand is for the Akuma and his right is for mankind. A cloaked figure forms over Bak and For and grabs onto Thread's threads, and thread, thinking the figure is someone else, lunges at the figure and attacks. When the cloaked figure surrounds and protects Bak and For, the Akuma slashes at it with its blades and releases hand-like extensions from its mouth to try to shatter it, but the mask of the figure leans forward until its at Thread's eye level before it fires multiple beams and starts to tear him apart.

As Thread is thrown back, screaming out in pain, the cloaked figure goes to Allen's hand, which is still sticking out of the water, and joins with him, and Thread becomes enraged and lunges at Allen as he emerges from the water in his new form. Allen effortlessly dodges as Thread falls to pieces, telling him to rest in peace before using his ability to immobilize what is left of its torso.

Before killing Thread, Allen asks the Akuma who had sent him. Thread asks if Allen will spare him if it answers, and when Allen says yes, Thread begins to laugh insanely, calling him a liar before admitting that it was Tyki who had sent him. The Akuma then openly wonders how Allen's comrades are doing in Edo, where the Earl and the Noah are gathered, before it freezes and wonders why it just admitted that aloud. Allen thanks the Akuma as it traces a cross through its body, and as it starts to die, Thread tells Allen that he can take the Ark Gate it had used to get to Edo.

Allen asks Thread why he would tell him that, and Thread says that it was because he was ordered to take Allen to Edo before changing his answer and saying that, for some reason, he felt "really good" before Allen's ability destroys him completely. As Thread dies, Allen wishes him a goodnight.
