Na-chan is Reiko’s best friend and Aki-chan’s third cousin. She has three older siblings and two younger ones. All of them, including her parents are geniuses. Natsuki, unlike the rest of her family is very outgoing and affectionate but just like the rest of her family, is extremely intelligent (although in her family they consider her the least intelligent due to her lacking a “focus”). Na-chan is very active in her extra-curricular activities often participating in school musicals and is the Public Relations Officer of the student council with her best friend Reiko, while also excelling in her academics and is at the top of her class, second only to the her hardworking best friend. Na-chan is very popular because she is genuinely nice and helpful to everyone. She loves stargazing and has a keen interest in astrophysics but also in music and dance. She is a DPS magic user and due to understanding of science (especially Astrophysics) she is naturally able to understand how her magic works better, amplified by her ability to connect with her feelings through the performing arts, she is by far the most powerful party member (After Reiko can no longer shield her from their After School Demon Fighting activities).

Akira Hideyoshi often referred to as Aki-chan, is the Twin Protagonists’ childhood best friend. He didn’t have siblings yet at the time, so he treated them like a younger brother and sister. Aki-chan is half American and half-Japanese. He lives with his single mom and much younger sister in Osaka. Although his family isn’t well off, due to his talent in multiple sports (starting out with Baseball and eventually branching off to Tennis and Lacrosse) he was given a full scholarship to the prestigious Tennoji High School. Although not the most academically intelligent, he does dream of eventually going into Sports Medicine.

Aki-chan is the healer of the party but isn’t the traditional kind. He wields a staff with a blade at the end so that he can cast spells and defend himself because he stays in the front lines (and won’t die easily because he’s pretty tough). Apart from his own healing spells, he heals passively creating the ultimate defence with Reiko, the party’s Tank.

Reiko Ishiyama is the “too rich and too good for anyone Student Council President.” Top of her class, Kendo varsity team captain, and rich daughter of the CEO of a security company. She handles the pressure with grace and shines with it. She is logical and practical but is caring and has a genuine want to better the lives of those around her. The problem is that she can be very difficult to approach due to being on the intimidating side and has difficulty connecting with those she is meant to lead. Her best friend Na-chan helps with that. She has a soft side for her best friend in the world Na-chan. The Kimono style-Rayon jacket in her summer outfit was a gift from Na-chan, a metaphor meant to symbolize that the moon, Reiko, will not be alone because she will be surrounded by stars (like Na-chan).
