My Oni Girl

Yearning to get along with others and not be disliked, first-year high school student Hiiragi lives in Japan's Yamagata prefecture and finds himself unable to say no whenever someone requests something of him. Even though he tries his best to do things for others, it never goes well, leaving him with no one he can call a friend. One summer day, while unsuccessfully carrying out yet another request, he encounters an oni girl named Tsumugi, who has come to the human world to search for her mother. She does whatever she pleases and is the complete opposite of Hiiragi.
