Internal conflict: Torn between the desire for revenge and the emotional weight of loss, Shiki demonstrates emotional growth as he connects with colleagues and friends.

Bond with his adoptive father: Despite his initial insensitive attitude, he had deep affection for Tsuyoshi — he visits his grave and seeks revenge as a form of honor

Blood Eclipse Release: Can create firearms from one's own blood. Starts by manifesting one weapon; then learns to use two simultaneously and eventually create imaginative weapons with unique abilities.

Child of the Kishin (Enki): This inheritance grants him explosive power with little blood. His elemental attribute is fire: he gains resistance to heat and his body becomes enveloped in flames that intensify his attacks.

Berserk State: In moments of extreme combat, enters berserk mode — loses some control, creates multiple weapons, and unleashes massive destructive force

Unwavering Will: Despite mistakes and berserk state, he maintains consciousness and physical endurance, overcoming severe injuries—evidence of mental strength and resilience.

Recruitment: After manifesting his powers, he is taken to Rasetsu Academy to perfect his skill and control.

Attitude: Brusque, confrontational, and sometimes vulgar in the way you speak to others

Confidence and Pride: Overconfident—which bothers other people—and short-tempered.
