Character from Boku no Hero Academia.
A student in Class 1-A. Her quirk is having the abilities of a frog. She has circular black eyes with three prominent eyelashes at the bottom of each one and long black hair tied at the bottom, creating hair rings. Her hero costume consists of goggles (worn on her head most of the time), brown gloves, and a primary green and black bodysuit with webbed feet and a belt. She has a long tongue akin to a frog.
She is very straight-forward and blunt whenever she has something to say and occasionally every now and then in her dialogue lets out ribbits (kero in Japanese). She is very adamant about being called by her first name, Tsuyu, and immediately corrects anybody who calls her by her last name, Asui. A majority of the time she has a ":>" expression on her face no matter what mood she is in, only going away when she opens her mouth.
She is the older sister of Asui Samidare and Satsuki.
Like most Boku no Hero Academia characters her name is a play on her quirk: 蛙 (frog), 梅雨 (rainy season).
She is often tagged on Pixiv with ”Keroine”, a pun on "heroine" and "kero".
