Ханао Кирюин

Hanao is the popular idol in the school, and the childhood friend of Takezou. Very pretty yet very bossy, she always causes trouble for Takezou. Plenty of boys in the school have a crush on her and have tried to confess their feelings for her, but she has no interest with them so she dumped every single one of them. A strange extraterrestrial incident occurred in the school that caused Hanao's body to grow in gigantic size. Her body will continue growing as long as her heart keeps throbbing especially because of the one person she likes the most. While she was very hesitant at first, Hanao, now as a giantess, must fight against other violent giantesses who have their own twisted ideals in order to prevent them from destroying humanity.
