Kokona Haruka

6
Kokona Haruka is a cheerful and friendly young woman who participates in the Drama Club at Akademi.
She is known around school for her eagerness to help others in need. If the Cooking Club needs someone to taste-test a new dish, she is the first to raise her hand. If the Science Club needs a test subject for their latest dangerous experiment, she volunteers without hesitation. This has led a few students to give her unflattering nicknames such as "test dummy" and "guinea pig," but she doesn't really see this as anything to be ashamed of.
There was once a point in time when she had a crush on Taro Yamada, but it was short-lived; she realized that the two of them had nothing in common, and moved on. It is very fortunate that she did not decide to pursue him; if she had remained interested in him, her life would have been in grave danger the following year, when Ayano developed an infatuation with Taro.
Kokona joined the Drama Club because of her deep admiration for the club's leader, Kizana Sunobu. (This admiration runs so deep that Kokona is willing to tolerate or outright ignore Kizana's numerous personality flaws.) Kokona's "twin drill" hairstyle was inspired by Kizana, who often styles her hair into very large ringlets.
