Trance Grimoire

The Hypnagogia Grimoire (夢現の魔道書) is a grimoire that appears in BlazBlue: Remix Heart. It has the power to enter a person's dream as they sleep. Depending on the victim's intentions, it can either cause incredibly enjoyable and happy dreams, or a living nightmare filled with the victim's worst fears, the latter usually surfacing if someone wanted to destroy the grimoire. If the person decides to stay in their dreams, he/she would abandon reality and never wake up. It can also bring drawings to life.

In the end, the grimoire got destroyed and vanished when Mai Natsume broke free from her despair.
