The enthusiast idol, Arisa is an energetic girl who is obsessed with idols.

Arisa loves idols very much, maybe too much. She has created a massive database that stores notes she's collected on every idol, which she proudly claims has information for every 2D and 3D idol in the business. The database has information such as an their age, hobbies, weight, skills, nicknames, and songs. She is also often seen around town with a high def camera, taking photos of idols in the wild, like an idol paparazzi. Occasionally, this camera even comes with her on stage when she herself is performing as an idol. Because of this, she's actually become quite a skilled photographer. Arisa has collected so much information on idols that it's often said she is capable of detecting an idol anywhere, even through their disguises.

A true Idol Otaku, Arisa has merchandise all throughout her room, which she cleans often. Surprisingly, some of these figures are of idols from the theater, such as Miki and Makoto, as well as an Akane-chan doll. When Arisa uses her computer to update her database, she wears glasses. This is probably due to her eyesight weakening with how often she uses the computer. Sometimes, Arisa stays up late at night watching lives, which often results in her being late to her own work as an idol.

Arisa auditioned to become an idol in order to get closer to the idols she admires. She is a very hard worker, and wishes to show off the fruits of her labor to everyone. She's even gone as far to teach herself the drums. However, Arisa does not see herself on the same level as the idols she admires, calling them way cuter than she could ever be. This lack of self-esteem also presents itself when Arisa is complemented, as she starts to cry because she doesn't know how to react to praise. She is slowly starting to improve her view on herself, so she can reach the idols she admires.

Occasionally, Arisa can't decide whether to prioritize her own work, or her love for idols. One time, even dashed away as she was about to go on stage to grab an idol's signature. Arisa's love for idols has existed in her since childhood, which is a dedication passed down to her from her father, who was also a huge idol fan. He took Arisa to a lot of idol concerts when she was small, which influenced her greatly.

Over time, Arisa becomes genuinely happy to be her own type of idol, and states that every idol is reaching a star that is slightly different from each others. She hopes one day she'll find a star of her own.
