Aina

Aina is a manifestation of 'The Guide to Salvation' that appears after Vaul burned the original book. She has the ability to call upon the Thirteen Knights and seems to go into a robotic trance whilst doing so however and begins to refer to everything as if she was a computer. Unfortunately, she cannot draw forth the maximum power of the Knights due to her not being the true Priestess of Salvation (Haruna is). It is stated that she drew her power directly from Shinya's memories and was jealous of his relationship with Haruna.
