柊小春

称呼海斗(カイト)为「哥哥」的少女，天主堂学院的初级生。 10年前的一次事故让她成了孤儿，之后就被学院所收养，在学院的保护下长大。 和海斗完全没有血缘关系，却不知为何叫他为「哥哥」。 对于海斗所做的事，她可说是100%肯定的。哪怕海斗偶尔会失言，她也会帮他敷衍过去。或许这就是“兄妹”间相信任的证据。 很喜欢被海斗当作妹妹来对待。 和别人交谈时总会用一些礼貌用语。求知欲很旺盛，也因此知识丰富，只是她的见解多少有点奇怪就是了。 害羞程度也算是正常级别。只是经常会任着好奇心而说出一些让人害羞的话，结果就反倒是自己变得消沉。 为了哥哥会想尽一切办法，用尽一切手段，只是绝大多数都在瞎忙而已。 食物方面爱憎很分明，基本上就是小孩子样，比较喜欢一些家常料理。 最讨厌胡萝卜，蔬菜也不喜欢，而汉堡包、炸鸡块、火腿肠之类的就很喜欢，最喜欢吃肉类（喜欢到对于肉类相关的知识了解到过份详细的地步了）。 「但是，请不要勉强哦。虽然在我看来你就是哥哥，但哥哥要把我当作一个女性对待也可以的。」

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. [From the Official Website]
