Notable Attacks/Techniques:

Immortality – Like all Ajin. Kei is completely immortal, he is unable to die under any circumstances such as being completely crushed, decapitated, or even due to malnutrition.

Paralysis Scream – When Kei screams he can paralyze the people around him, its been stated to have less of an effect if the person is unaware the user is an Ajin

Black Ghost (IBM) – Like all Ajin, Kei can release a "Black Ghost" which does not require his physical body to move. Kei has been able to unconsciously release his ghost at a very young age, even before his first experience of death. However years of lack of association between him and his ghost has lead to it being extremely disobedient and self-propelled, acting independently with a mind of its own. As stated by Ikuya, Kei holds an abnormal amount of IBM in his system, making it extremely concentrated when it is released, it is even capable of fogging the sight of an Ajin. Kei's IBM when manifested into solid form, unlike ghosts of other Ajin, is considerably plain without any distinct deformity. It is known that he can summon multiple ghosts and can hold out for as long as 30 minutes. He has stated that "on a good day" he can summon nine ghosts but normally five, a result of his high IBM concentration.
