Overview

Riho Sanada is a third-year high school student and a girlfriend of Nae. Coming from a sufficiently wealthy family who dabbles in the tech business, Riho has impeccable manners coupled with good grades and good looks. Knowing fully the fortes she has, she tends to be imposing in her conduct and likes to assert her dominance. Although she shares the characteristics school bullies usually have, she could care less about other people's business. Rather, she likes pestering those she finds intriguing by getting close to them in a non-malicious teasing way.

As dreading as she sounds, she can be especially nice when she tries. On the other hand, despite her perfect image, she has somewhat bizarre humor and antics, as well. She likes to pull some hijinks just for fun and giggles, with Nae and Kei as her regular victims. As meddlesome, bossy, and fearless as she can be, it turns out that she is easily frightened by darkness. Hence, she has a weakness in haunted-house attraction or sleeping in the dark.
