Registered Ability

Beast Beneath the Moonlight · 月下獣

Atsushi transforms into a white tiger whose speed, claws, and regeneration overwhelm a normal battlefield. The file notes that the ability answers strongest when fear turns into resolve.

Trait Assessment

Literary Origin

Nakajima was a Japanese modernist writer whose work often circled identity, alienation, and the pressure of living up to impossible standards. His prose carries both classical gravity and deep psychological unease.

The tiger form draws directly from Sangetsuki, where a man is consumed by the beast hidden inside his own pride and fear. BSD turns that inner metamorphosis into a visible combat signature.

Lore & Background

Orphaned and cast out, Atsushi was found by Dazai and recruited into the Agency. He represents the city's hope for redemption. His value to the city exceeds even his own understanding, as he remains the primary target for several international organizations.

Registry Note
