Dragon Fist(1988)

Dragon Fist

Born as an aberration different from the expectations of a chief's son, Fei Long has been ostracized by his own people. To prepare for his destined future role as chief of his clan, Fei Long is sent to Japan to complete his schooling and gain experience mingling with humans. In Japan, he discovers not everything is simple.

Note: This manga has been published one volume per year for 12 years, so the artistic style changes rather drastically as you read further on. It's a chronicle of sorts of Katayama Shuu's growth as an artist.
