A 2nd grader of Mihama Academy, Matsushima Michiru only acts like a tsundere character because she is highly interested with them. Nevertheless, her silly and energetic personality makes her the mood maker of her class, even if she’s really bad at studying. Michiru is known for carrying a shark-shaped pouch around her waist containing lemonade sweets.
She’s so adorable! And she does kind of look tsundere in the photo, don’t you think? Thanks again to Michelle for sending this in!
EDIT: Thanks to Tsuji for letting me know the cosplayer’s name is Enako!
