I'm planning on rewriting this story where Iroha is the protagonist instead of Yuma and Ui exists.

Astral is a being from the key that is tied in her hair like the pink diamond in her hair, there will be some Zexal characters.

Astral only knows and remembers Iroha to be his wife when they meet during a duel with Shark.

Iroha is a Magical Girl but she will sometimes duel and fight witches.
