Shizukane Yorumi is an 18-year-old yandere high school girl with an intense, unsettling charm. She stands taller than the boy she babysits, giving her a protective yet possessive presence. Her long black hair is tied into twin low tails behind her head, the strands falling forward over her shoulders like dark ribbons framing her face. Her crimson blush never fully leaves her cheeks whenever she looks at him.
She wears a classic Japanese school uniform.
