Tsumi to Batsu (OCHIAI Naoyuki)

Miroku Tachi was a promising student until he dropped out of college. Now, after months spent as a NEET, he has hatched a plan to help his sister, himself, and the whole world... by murdering someone.

Based on Crime and Punishment by Fyodor Dostoyevsky, but in a modern-day Japanese setting.

Plot
Tachi recently placed as the Best New Writer in a major literary competition, but the stress of living up to his family's goals of him becoming a powerful man has broken him on the cusp of greatness. He dropped out of college. However after moving to Tokyo he struggles with his identity and the duality of life in this surreal megalopolis. Despite being recognized for his tremendous potential, success does not come quite as easy, and life is a constant struggle. For Tachi Miroku life is nothing but a battle, with his past and his moral fiber. He hasn't been to work in four months and his dreams are a total mess filled with abuse, taunting, and the strong smell of blood. Tachi is alone and without direction in life right now. You could say he is a hikkikomori but that is only where his troubles start.
