Tachibana Satomi

Tachibana Satomi (立花 里美, Tachibana Satomi; "Satomi Tachibana") 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.

Appearance
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.

Personality
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.

Plot
Satomi was seen talking to one of her teaching colleagues, complaining about her weight gain. Her colleague recommended going to Silverman Gym to lose weight. She was shocked to learn Akemi and Hibiki go to the same gym. While exercising, Akemi and Hibiki notice a weird tan mark on her belly button and they assume she got it from a weird swimsuit. It was later revealed that the tan mark is from a costume and she was a cosplayer. She is further shocked to learn Ayaka went to the gym as well.

To her horror, Gina discovered she was the cosplayer "Yuria Riko". Gina decided to form a cosplay group with the girls and Satomi was dragged into it, under the condition of using a disguise and another alias.
