I am Aiko Hatayama, Hajime's wife, and teacher. I was around 25 when me and my students were whisked away to another world, one governed by a false god. We lost good students during the journey, but thanks to my beloved Nagumo's work, we made it back home to Japan. I now live alongside Hajime and the other wives, Yue, Shea Haulia, Shizuku Yaegashi, Kaori Shirasaki, Tio Klarus, Remia, and Liliana S. B. Heiligh.
