Aiko Hatayama

Aiko Hatayama is a main character from the "Arifureta Shokugyō de Sekai Saikyō" series.

She is a high school social studies teacher, who along with her students from Japan, was involved in the summoning incident and ended up in Tortus.

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 feelings of people who fell in love with her as being friendly. Even as a child, she was always focused on obeying the rules and reprimanded anyone that broke them. She never compromises on her ideals; even when they contradict with her feelings.

Aiko has always had a strong moral nature and can be very stubborn. She carries the belief that a teacher should always protect their student above all and be there for them. This caused her to be too idealist for her own sake, even to the point where she contradict herself. Such as not wanting to get her students involved in anything dangerous or to solve their problems through violence yet convinced Hajime to protect the town of Ur because he was strong enough to do so, something she knew was a contradiction. Furthermore, she kept trying to reason with Yukitoshi and even wanted to save his life after he tried to kill her, her students and the town of Ur, simply because she was his teacher. Hajime felt she need to be more realist despite respecting Aikos' moral code. He even went as far as to kill Yukitoshi himself so Aiko wouldn't break down from needlessly blaming herself for his death.

After recognizing how most of her ideals were already dead, Aiko started resolving 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 to keep Ishtar and the bishops from killing Hajime. 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 her students, now taking the time to consider their reasons for their actions instead of expecting them to go along with her wishes and getting upset when they don't. She didn't believe she had the right to blame Hajime for killing Daisuke because she knew he was furious after seeing he had killed Kaori, someone precious to him.

Aiko has always been terrible at keeping secrets. This is because she tends to openly express her feelings without meaning to, making it easy for those that know her to guess what's bothering her. This allowed her family and childhood friend to figure out her lover was one of her students.

Aiko is surprisingly very charismatic, something that has proven useful for her in Tortus, leading to her becoming worshiped as a goddess by the people. This is the result of her hard working nature, strong moral character and her cute appearance. Most of her students respect her immensely and have shown a strong desire to protect. Even after his transformation, Hajime still had respect for Aiko and was willing to trust her with the truth about Ehit and let her decide what she's was going to do with it. All the knights from the Holy Church who were originally suppose to seduce her Aiko end up falling for her instead and became more loyal to Aiko than the church.

After becoming Hajime's wife, Aiko has picked up some of his violent traits, such as being brutal against anyone that would threaten her family.

 * Spirit Magic - One of the "Ancient Magics" originating from the "Age of God", which allows the user to manipulate the soul of a living being directly. It's possible to revive a living being back from the dead (time restriction applicable), or transfer the soul of a living being from one body to another, or even into a non-physical body as well, practically granting any living being immortality. The true power of this magic is the ability to 'interfere with the negative material possessed by living thing'. To be more specific, this magic could also interfere with things like energy inside the body that was mana, heat, electricity, then thought, consciousness, memory. Those who have mastery over this magic can even create an artificial consciousness, and allow it to inhabit any body they wish.

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."
