未島 海晴

A student at Amecha Girls' University High School, and one of Rinka's classmates. While beautiful with the brains to match, others consider her difficult to approach, which results in her being avoided much like Rinka. As one would imagine, studying is her specialty, to the point where she can go for long hours without any breaks once she gets into it. Her eating habits would indicate that she isn't fussy in the slightest, but in reality she simply doesn't care much for taste in the first place. She works part-time at a certain restaurant, but apparently she's yet to ask Rinka and Mao to come along at some point.

While typically level-headed, she sometimes speaks her mind without hesitation, leading to some harsh takes now and then. Her circumstances while growing up seem to be somewhat complicated, but not even Rinka knows much about it.

Her feelings for Rinka surpass the boundaries of simple friendship, but Rinka herself seems to be completely clueless about this.

Her name card reads 'II - Name - Hebinata Miharu'. Hebinata was her father's surname, and is her preferred one.
