Kousuke Asazuki

The most arrogant, aggressive and most violent of all the Blade Children Kousuke is usually the implementor of assassinations. Kousuke is very strong-willed and stubborn, choosing to fight the Hunters head on rather than hide from them. He is impulsive, impatient, and tends to resort to physical violence over verbal negotiation. He is not afraid to kill and does not really trust Eyes, resulting in arguments between them. While Rio calls him stupid, in reality Kousuke is very intelligent; after skipping most of elementary school, he still manages to catch up to secondary school level from reading and learning from books. Kousuke also left middle school after a run in with a teacher.

Kousuke may also have some romantic feelings for Ryoko.
