Summary
Samejima was a senior at Ichitaka’s high school and serves as the primary recurring antagonist of the manga. Described as a sexual deviant, he attempts to exploit Iori on at least three separate occasions using different schemes, though Ichitaka thwarts each of his plans. Following the failure of his first attempt, he is expelled from the school. His second attempt drives him to become a drug addict teetering on the edge of insanity, leading to his significant involvement in the manga’s final story arc. He operates under the online alias "Marionette King," and his true name is never revealed in the main series. However, his real name is finally identified as Samejima in the Is Pure OVA.
