No Zo Ki A Na

Synopsis

Kido Tatsuhiko moved to Tokyo to attend an art school and start his new life. In his new room, there's a small hole in the wall. At first he can see nothing through the small hole, but one night, through the peeping hole, he saw a girl named Ikuno Emiru, a perverted voyeur who ropes him into her peeping fetish... But each winds up getting more than they bargained for.

Bundled with the limited edition of the manga's 13th and final volume.
