Satomi Tachibana

Tachibana Satomi is one of the main protagonists of Dumbbell Nan-Kilo Moteru?. She is a world history teacher at Koyo Girl's Academy, and joins the Silverman Gym shortly after Hibiki and Akemi. Satomi is a woman with chin-length black hair with parted bangs. She has a diamond tan mark over her belly button. She has a mole under her left eye. Satomi likes to cosplay but she is embarrassed by her hobby so she tries to hide it from her students, especially Hibiki and Akemi, whenever she meets them. She is also afraid that she'll be fired if the school board finds out about her hobby. However, because she loves anime and cosplay so much, she'll go on a rant if someone lets her. Much like her fellow teachers Aina Rumika and Kure Yakusha, Satomi gets irked by remarks regarding her age.
