She re-met Erza and soon the other Fairy Tail Members. She was very distant with the members of the guild and would stay in the back.

Demon Soul (鬼·ソウル Oni Sōru) is a Caster Type Magic and a form of Take Over. This particular form of Take Over is strange in its own way being that it manifests from the Aiko's subconsious thoughts and hidden desires. As this magic drains a large amount Eternano, only 3% will  survive after it's use. The 1% who are lucky have the ability to use this magic on several occasions. Additionally, because of the heavy strain, Aiko can be commatised, lose her ability to use Eternano, or face eternal slumber.

Vampire (Kyūketsuki,吸血鬼): Aiko is half Vampire, though she isn't dead. Since her father was a vampire it ran through her family that's why she was born with blood red eyes. She needs to suck people's blood daily only way for her to live. Though she is able to resist sucking people's blood.
