Majin Tensei (魔神転生?, lit. Demon God Reincarnation) is a tactical role-playing game spin-off series from another Atlus series, Megami Tensei. The series contains MegaTen game elements, among them the concept of demons, demon races, and the summoning of demons. Players and critics comment on the similarities to Nintendo's Fire Emblem series, both graphically and gameplay wise.
There are three games in the Majin Tensei series, with one spin-off. All four of the games have never been released outside of their native country Japan.
