Appearance
Aiko is a petite woman often described as having a childlike figure by her students. She has dark brown hair and eyes (green eyes in the anime).

Personality
Aiko is a very responsible teacher and cares a lot for her students. She often misunderstands the peoples feelings of affection for her as being friendly. Even as a child, she was always focused on obeying the rules and reprimanded anyone that broke them. She had a strong moral nature, can be very stubborn and carries the belief that as a teacher she should always protect her student above all and be there for them. This caused her to be too idealistic, to the point where she often contradict herself. Such as not wanting to get her students to be involved in anything dangerous or to solve their problems through violence yet convinced one of her students to protect the town of Ur from the invasion, something she knew as a contradiction of her own beliefs. Furthermore, she kept trying to reason with Yukitoshi and even wanted to save his life after he tried to kill her.

After recognizing how most of her ideals were already dead, Aiko resolved herself to better protect her student instead of being the one being protected. This is displayed when she chose to fight against the Holy Church alongside Tio. And while she admit she didn't regret her actions, her strong morals still caused her a lot of pain because she had become a murderer. She also stop trying to force her ideals on to others and now taking the time to consider the reasons for their actions instead of expecting them to go along with her wishes.

Aiko is also very charismatic, leading her to be worshiped as a deity in Tortus. This was the result of her hard working nature, strong moral character and her cute appearance. She has always been terrible at keeping secrets and tends to openly express her feelings making it easy for those who know her to guess what's bothering her.

Quotes

 * (To Hajime Nagumo): "Nagumo-kun, I understand that you have your own principles, and that you’ve already decided your path for the future. I won’t try to change that, but I also think that no matter which future you choose, it’s... too lonely to only live by ignoring everyone aside from those you care about. If you keep going like this, neither you nor the people you cherish will find happiness. If you want to find happiness... you can’t lose sight of your kindness or empathy. You have to think of other people, even if it’s only a little. Those are valuable qualities you possessed from the start... Please don’t throw them away."
