Gyakuten Isekai no Kyuuseishu: Isekai Trip shita Saki de Bijo ni Kansha sare, Icha Love Seikatsu Okuttemasu

Tomoaki Yushima, an ordinary college student who took a trip to another world.

This world was reversed on appearances, chastity, and lust.
With beauties having no place to go, they gathered to create a town―Blossom.

Due to being proved to be their town mayor, will Tomoaki lead an erotic life?!
