Able to summon any page within her, can use magic
Mei appears to be a little girl around the age of 8, however she is over 1000 years old, and other then that is she is really a book, a grimoire to be exact. Every starter magician is given a grimoire that connects to their soul, these special grimoires are called Soul Grimoires, or Book Heart. This grimoire girl belonged to Mia. Even though Mei was just some magic book, it was Mia's best friend, and was always carried around like a doll. But when Mia turned immortal Mei was looked away into a secret room. It was because the older the magician, the more bigger and powerful the book becomes. Even though most Soul Grimoires become lost in time, because Mia became immortal so did Mei and she managed to live on, growing more powerful and gaining more stronger spells. Eventually Mei contained spells so powerful it can summon almighty gods from the heavens! After around 1000 years have gone past though, Mia managed to find the stored away book. But when she came into contact with the lock, the book went haiwire and teleported itself somewhere else. After reciting a spell by itself, Mei was born. Mei later became to be Mia's servant, however is treated more like a daughter.
However Mia protects Mei very heavily, because Mei's power and spells might make her the most powerful thing in Hayashi...
Mei has the power to summon a page from herself when ever it is desired. So even if she's in humanoid form she still contains the spells as she was a book. It was also revealed that she has great memory of the spells, it could be because she has them written inside her.
