Dragon Clan: Lu Mingfei Returns from Japan

Lu Mingfei, the Japanese light hero who returned from another world, exudes an Asian aura.

PS: This is an orderly guide, not brainless, with daily campus life as the main tone, but it will still retain the settings and important storylines in the original work. The settings are based on the first three parts of Dragon Tribe, and the last three parts are used as supplements.
