Aiko Hatayama (はたやまあい, Hatayama Aiko?) is a main character from the "Arifureta Shokugyō de Sekai Saikyō" series.

She is the Homeroom Teacher who along with her students from Japan got involved in the summoning incident, and ended up in Tortus.


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).


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 theme. She never compromises on her ideals; even when the contradict with her feelings.


Aiko grew up in a small town to a family of farmers on her mother's side. When she was young, she was framed for stealing a bike by another classmate who was the son of one of the town's wealthy and influential families. The only person who stood by her side, other than her family and friends, was her teacher that all her students despised for his strict attitude. He managed to clear Aiko's name through his efforts, but was forced to retire due to angering the boy's family. His willingness to stick up for her inspired Aiko to become a teacher that would always support her students.


At first she wanted the students to abstain from fighting but gave up because the students want to help to return to their home world. When she saw Hajime and discovered he was alive she was shocked by the sudden changes of his figure and attitude but fell for him when she was saved from being poisoned through being fed with Ambrosia mouth to mouth.

  • (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."[1]
