Satomi has a secret life that she hides from everyone around her. When she isn't teaching, Satomi loves to cosplay and has grown as a large fanbase under the alias Yulia Riko. Satomi's secret life as Yulia Riko is one of the best things about things about her because it shows off all of the drive and passion she has for it. It is also hilarious seeing how far she will go to try and from finding out about her secret.

Most of the time  Satomi is kind and confident and she never lets anything get to her. However, there are a few times when we get to her a more shy and bashful side to her. Whenever her life as a famous cosplayer is brought up by gina, we get to see this cute side to Satomi. It's nice to experience all of Satomi's great personality traits, but her shy side is by far the best.

Whenever there is something crazy going in Dumbbell Nan Kilo Moteru? Satomi often gets the role of the straight man.  All of her reactions to the insane antics of the other members of Silverman Gym make her a lot more likable and relatable. While she doesn't get as many humorous moments as the other characters in the series, her realistic viewpoint and reactions make her one of the best characters in Dumbbell Nan Kilo Moteru?

No matter what Satomi is doing she always gives it her all. Whether it is her job as a teacher or her cosplay, she puts everything she has into and never quits when things get difficult or awkward. We see this when she first joins Silverman Gym and despite being reluctant to start working out there, once she got started, she dedicated herself to working out.

Satomi finds herself dragged into an idol audition after Gina convinces all of the girls to join her. As a reluctant member of the Muscle Gals, Satomi hides her face from the crowd and takes on an intense and abrasive personality. This is one of Satomi's best moments in the series. Despite wanting nothing to do with the idol auditions she still gives it her all and even goes as far as to do a deadlift to try and impress the judges.
