A hedonist scattering hallucinogenic scales. A mistake hidden behind a flippant smile.

・Accompanied by long years of operation and the accumulation of inmates' emotions, he came to acquire and manifest ███.
Aldea, a world where monsters and humans coexist.
There, a facility exists to house "Abnormal Entities"—
those with powers and forms different from ordinary humans.
—Abnormal Entity Protection & Rehabilitation Facility 《Gugoku》
Those who have committed sins. Those suspected of committing sins. And those who believe themselves to be sinners.
Everyone gathered here wears their own "surface facade."
The laughing Jester The obedient Doll The broken Glass The Boundary of righteousness The Butterfly seeking freedom
—But the sins left in the records are not necessarily the truth.
Into such a place, Gugoku, Guest sets foot.
From that moment, someone's lies and someone's truths begin to quietly peel away.
