Futakoi Alternative

Rentaro Futaba inherits his father's detective agency and shares both work and everyday life with twin sisters Sara and Soju. Between minor cases and the disorder that follows him, their companionship becomes the center of his uncertain new life.

The arrangement is hardly sheltered from danger. Run-ins with local gangsters and the hazards of his trade pull Rentaro into trouble far larger than his small agency, testing the unusual happiness the three have found together.
