Two characters in the popular anime/manga series D. Gray-Man. Other names for them include Jasdavi, Jasdevi, and Jasdavid. They are twin brothers named Jasdero and Debitto. They prefer to go by the singularity Jasdebi because they hate being referred to as "the twins." They are part of the Noah Clan, a group of superhumans who follow the Millennium Earl. They both carry six-round revolvers and tend to aim them at various objects and people, even each other. They are short-tempered and are also very immature and overconfident. Debitto plays the role of the older brother and seems to be the more calculating of the two. Other names for him are Debito, Devito, and David. Jasdero is more submissive and also seems sort of feral. Other names for him are Jasdello, Jasdelo, and Jasudero. They are able to merge into a single entity by shooting each other in the head. In this form they no longer use their revolvers, choosing to use their long hair as a weapon.
they represent the "bonds" of Noah
Their preferred techniques include:
Blue Bomb (青ボム): Freezes anything they hit
Red Bomb (赤ボム): Creates a large fireball
White Bomb (白ボム): Erases anything; think of this as the opposite of Materialization. (used to erase the fireballs that Lavi and Krory hit back at them)
Purple Bomb (紫ボム): "Deceiving Spectacles"; a mask-like cover of paint that covers the eyes of the enemies and cause them to see any illusion that the twins want.
Green Bomb (緑ボム): A person is trapped in a bubble filled with slime.
Jasdevi's Hate (ジャスデビの怨念): Materializes a monster that seems to be made of numerous dead human bodies. The monster moves according to Jasdevi's will.
"Materialization": They had materialized an illusion of the Earl that is derived from a past memory and an iron maiden used to trap Krory.
I heart them
