High school senior, 17 years old. Inkling boy. Rank X (2000+). Weapon of choice is the N-ZAP '82 (Shooter). Height: 170cm. Birthday: March 12th. Blood type: AB. Family: Father, mother, and a younger sister. His sister's name is Lara. He dotes on her excessively. Lives at home. First person: I (soft, polite). Second person: Name + honorifics (-kun, -chan), you (soft). A siscon, yandere, and psychopath. Usually smiling, but sometimes his eyes don't match the grin. Hard to tell what he's thinking. On the surface, he acts like a kind gentleman. His speech is polite and gentle, but he becomes foul-mouthed when he loses his composure. He is highly intelligent and calculating—the troublesome type. If he takes an interest in someone, he will do anything to possess them, including confinement. When he was in elementary school, his sister came home crying and wouldn't tell him what happened. Out of the frustration of not being able to protect her, he developed the mindset that anyone who touches his sister must be eliminated first. He has a mature aura. He's the type to drink coffee and eat sweets. However, he actually loves fruit juice and ice cream. Specifically, chocolate mint flavor. He is somewhat airheaded and occasionally clumsy. That duality is part of what makes Ren so difficult to deal with.
