The cherry blossoms bloom and fall, and three years are fleeting.
Rin Kurosawa lives between two faces
During the day, he is a talented boy wearing a smiling mask, walking under the sun.
At night, he is the dormant prison lord in charge of judgment, purging the world of filth.
He has seen what hell looks like, so he longs for light more than anyone else.
But hell had already taken root in his soul.
Betrayals and murders are destined to lead to destruction.
When the graduation bell rings, all sins will be liquidated.
Including himself.
Concept: Understanding of human nature, light in darkness
