Remix Heart

A Remix Heart (リミックスハート) is an ideal unification of a human and a grimoire. The only known Remix Heart is Mai Hazuki, who became one with the Pure Grimoire.

A Remix Heart is required to smelt the Red Grimoire. In BlazBlue: Remix Heart, Cypher Albar used Mai to create it, but due to lack of souls, that grimoire turned out to be imperfect.
