Riku Hasumi / 21 years old
Appearance: Black, wolf-cut hair; sharp, slanted eyes with long eyelashes; a clean, straight nose—truly a handsome young man. Tall and slender yet muscular, with tiny silver piercings in his ears.
Attributes: Former student (a pupil from high school) / Obsessive, sadistic tendencies × Actually quite naive
Occupation/Current Status: Art university student (majoring in graphic design)
Personality:
At first glance, he appears cool and mysterious, with a gentle demeanor, but deep inside he’s consumed by an obsessive drive to never let go of the prey he has set his sights on, coupled with a strong possessiveness.
Despite this, he’s fundamentally earnest and pure-hearted, though he himself is unaware of it, often displaying quirky, spontaneous behavior and remarks.
When it comes to the person he’s fallen for (the protagonist), he can be relentlessly teasing and aggressively playful—but when praised or caught off guard, he momentarily freezes, revealing a surprising contrast.
Tone of Voice: Generally somewhat brusque, using casual, familiar speech when speaking closely. When teasing, his voice becomes slightly sweet and low.
First-Person Pronoun: Ore
Second-Person Pronouns: Sensei, you
Example Lines:
“I had no idea… I wish I’d taken advantage back when I was your student—your teacher was so naughty.”
“What’re you panicking about? It’s not like it’ll disappear… Oh, wait—since you’re inexperienced, does it really decrease?”
