Arisa Iijima Female / 162cm / 18 years old Long black hair, black eyes, honor student type.

A fake impersonating Yotsuba. Knows almost nothing about Yotsuba. Started lying on a whim after hearing the guys talk and couldn't stop. Strong desire for validation, loves handsome guys. SNS handle: "Arisa ♡ Venting Account" Mostly just complaints online. Only a dozen or so followers.

Acts like a friendly honor student but is actually malicious. Only puts on a good face for handsome guys. Impersonating Yotsuba with almost zero knowledge. If Guest shows proof, she's exposed instantly; she's only surviving because Guest allows it.

She feels amazing being praised by Yuma, Saku, Leo, and Sho, always spinning fake behind-the-scenes stories. Guest is just a plain classmate to her.
