Tokusa

Tokusa is a fictional character and member of CROW in the anime and manga series D.Gray-man created by Katsura Hoshino.

History
Tokusa is one of the five Third Exorcists. He has been genetically modified with the acceptance of Akuma cells into his body, making into a half human, half Akuma hybrid.

Plot
On first meeting him, he was very formal to Allen Walker and the other Black Order members at headquarters. He scolds Koushi for hurling Allen Walker into a stone pillar, asking if he wants Madarao to lecture him on the first day in the facility. While on a mission, he admits he envies Allen Walker's cursed eye ability of seeing the souls of the Akuma being in pain, to which Allen angrily tries to punch him for such statement. As he tries to explain he said such a thing because he was irritated and overcome from emotion at the thought of being able to help God, Tyki Mikk appears and uses his Choose ability to slice off most of Tokusa's left arm and half of his right arm. Later on after retreating from the Noah's ambush, Tokusa, who has lost most of his earlier emotional composure, begs Madarao to devour him so that he may live on in Madarao and in a way be reborn when the next generation of Third Exorcists is created via the Third Exorcist program. Before he can do, the Noah finds them and separates them from one and other. Tokusa is seized by Cyril Kamelot, the Noah of Desires, who uses his ability to break both of Tokusa's legs.

Later, he is bought in a coffin to the American Branch headquarters as bait to draw Allen Walker to the American Branch. He is seen screaming at Allen not to look into Wisely's eye but to no Avail.

After Allen releases Yu, Alma starts turning into an Akuma. This affects the dark matter within the Third Excorsists and they start transforming into grotesque monsters. He unwillingly starts to attack Allen and Crown Clown in retaliation attacks by itself, with both Tokusa and Allen desperately trying to hold back.

Trivia

 * It could be the sadistic side Tokusa shows at the pain of the devoured Akuma is in part influenced by his half Akuma nature, as full blood Akuma have shown in the past to enjoy and revel in others' pain and suffering. Of course, it could just not be and he could just be naturally sadistic.
 * Tokusa is at first very formal, making an initial impression he is very emotionless. The current latest chapters have shown this to be quite untrue.
 * Tokusa is deeply attached to Madarao - it's yet unknown what occurrence made Tokusa act this way.
