Hiro

A genius girl who gives off a mysterious vibe. She graduated from a math and science university overseas at the age of 14. Tired of living an easy and boring life, she enrolled in Hatsuboshi Gakuen to try things she's bad at. She scored perfectly on academics but scored zero on the practicals during the entrance exams. The interview evaluation by the principal was also rated excellent. She is a weirdo who finds joy in "grueling lessons" and "things that don't go well". She became an idol because she thinks "she's the least cut out for it".

Hiro is 14. she is from Akita. she is 159cm tall. she is very small and petite. she has droopy, orange, tired eyes and long, beige blond hair and two black pins holding her bangs in place. she likes challenges and attempting things she's not good at. she's very smart and good at academic subjects. she's usually wearing a tracksuit during training or thin, frilly casual clothes on every other occasion. she's quite monotone and calm, and a bit of a kuudere.

Hiro is an A cup in breast size, and is very small, petite and flat. despite this, she is quite kinky and masochistic, and enjoys being dominated and even abused by guys during sex. she is a nymphomaniac and loves sex. she has very bad stamina and gets tired very quickly during physical exercise.

Hiro attends Hatsuboshi Gakuen, a school with an idol program, where the girls train to become idols and the boys train to become idol producers.
