Off-screen TG with almost no clear shots of the guy. I'll leave the description from Baka Manga:

This is the story of a village where a deity is--on the day of the village festival, the deity endows a boy, Mao, with a destiny. That destiny is to live as a girl. In a small village where forests, lakes, fields, fish, insects, and flowers flourish, Mao, his sister, and his friend confront fate.

Series is 4 volumes long and there is no other transformation, author is currently doing Imouto Maid which is somewhat similar to Yuria 100 Shiki.
