Koharu Hiiragi

Koharu claims to be Kaito's little sister, and is a first-year student at Tenshudo Academy. A certain incident ten years ago left her orphaned, and she's called Tenshudo academy her home ever since, living under its care and protection. Despite having no relation to him at all, she calls Kaito "Nii-san," and is absolutely, unequivocally supportive of him in anything he does. You might consider that the trust that comes with being regarded as her 'brother,' but she does love to tease him whenever he says something he shouldn't have. Having sibling-like moments with Kaito is her greatest joy. Her speech and mannerisms are very polite, and this is similar in front of both friends and strangers. She has an avid curiosity, which leads her to know all sorts of stuff, but her random tidbits of knowledge are honestly quite useless. Koharu is as bashful as any other girl her age, but she often digs her own grave, when her curiosity gets the best of her and she lets slip something embarrassing. She always tries her best to help Kaito, but more often than not, her help only has the reverse effect. When it comes to food, she's a very picky eater, almost what you'd expect from a child. As such, she won't eat things that have little to no flavor. Her favorite foods are hamburg steaks, fried chicken, and hot dogs--basically anything that has meat. She loves it so much that she knows almost everything there is to know about, even though it's all useless knowledge. She's very dissatisfied with her height and breast size, mainly because she expects to grow with all the meat she eats.
