Mashiro is tolerant and level-headed, but that just makes rousing her anger all the more terrifying. She may seem naive, but that's just because her understanding of the world is a few years out of date.

● Ameri Kawai, VA: Kaori Hanano

The childhood friend and classmate of the protagonist, Yuri. She's a student in the Slightly department of Sohsei Academy, where her father is also the director. Lately, her favorite pastime is teasing Yuri and Sankuro.

She can be persistent and persuasive in drawing others into her way of handling things, but when it comes to love, she's a bit on the timid side...

● Mifuyu Kisaragi, VA: Rina Misaki

She is the Lady, the Prefect, of the Flawless Girls' Boarding Department of Sohsei Academy. As the heir to the aristocratic Kisaragi Conglomerate, Mifuyu has been raised to be both strong of character and someone others will naturally rally behind. She's well trained in many things, including swordsmanship and martial arts. But that doesn't mean she isn't without her flaws.

She's rather fond of romance novels, the kind where things are depicted a little too pure for reality. Which will certainly make things tough for a red-blooded man...

● Yumina Takanashi, VA: Yu Aoto

Yumina looks up to Yuri as an older brother. When her birth parents went bankrupt, they gave her to the Mito family to raise. Unfortunately, Mari Mito, the family matron, passes away long before the start of our story, and Yumina is ultimately adopted to the Takanashi family out of concern of a lack of mother figure.

She's one of those people who immediately fails at a task whenever someone is watching out of nervousness. But she doesn't mind working hard, and she's actually rather good at handling the household chores. She tends to get lost in her own imagination.

After Mifuyu offered to become her guardian, she quickly grew attached and now brings a cheerful, innocent energy that puts everyone at ease.

● Ouryu, VA: Taiyo Sorano

One of the Three Mightiest Tayutai, dangerous beings sealed away in ancient ruins by Kikuramikami no Hime.

Once thought to see humans as nothing more than prey, it turns out the truth is quite the opposite—he simply envisioned a different kind of coexistence from Mashiro.

Though he usually hides in the pond in the Kawai family's garden, he often takes human form to walk among people.
