...'s manga / #Kuraka Sui(4)

Sequel: Itou-san

The ending was open-ended but somewhat satisfying because of maybe.. another chance. Chapters 1-6: itou-san, a hired wired assassin, fell in love with a prostitute, who somewhat fell for him also but breaking the assassin's rule means death so they try to escape for their freedom. Chapter 7: student and teacher using each other, totally broken and twisted, heavy Bdsm [DO NOT READ AGAIN] Chapter 7.5: a parallel world of main story, school setting as teacher and student. Chapter 7.6: happy ending. Chapter 7.7: happy ending after.
