Tanabe Yellow Manga

By night, junior high student Yoshimori Sumimura is a "kekkaishi"--a demon-hunter who specializes in creating magical barriers around his prey. By day, Yoshimori's got some other demons to battle: an addiction to sweets and a seriously crotchety grandfather! Yoshimori's pretty 16-year-old neighbor and childhood friend, Tokine Yukimura, is also a kekkaishi, but their families are feuding over who is the true practitioner of the art. Kekkaishi received the 2007 Shogakukan Manga Award for shounen manga.

Eishi Karasuma (15 years) is a loner with a monotone life. His only friend is Mikisada Komoda (14 year). They venture together while skipping course.

On their way back, Eishi and Mikisada take a bus which lose its track and fell from a cliff. Eishi tries to go out when he suddenly spots a young boy with wings...
