"Stop it, don’t decide everything by yourself. You said you wanted to be friends, right? Let me be part of things too! I know Lilysa is kind, but that’s the same for everyone! Then what does being friends even mean? What’s something I can do because I’m not a stranger? Don’t carry everything alone! Tell us what you want to do with everyone! Maybe I can’t do it, maybe I’ll say it’s too much, but still—let’s do it together! If I don’t want to, or if I can’t, I’ll tell you. Don’t worry about it! I can tell you how I feel now!"

First Appearance and Cosplay Debut
Nonoa starts as a first-year high school student from a different school than the main characters.
Despite her shyness, she becomes noticed as a top new cosplayer with her Kuuria costume from the game "Cinderella☆Star," standing out for her cool look.
She and Lilysa Amano are known as possible "Next Four Emperors" after Mayuri Hanyu graduates from her role in the club.
Overcoming Her Past and Making Friends
Nonoa’s struggle with talking to others comes from being rejected in the past for talking about her favorite anime.
This caused her to become afraid of being herself around other people.
Cosplaying allows her to act differently, making her seem cool and confident even though she is very shy inside.
She meets the club through a cosplay event and finds real friends for the first time.
Over time, her negative thinking gets better because of her new friendships.
Everyday Life and Mochi Form
Nonoa enjoys spending time in the clubroom and now calls Masamune Okumura’s school her “real school.”
She is so often shown in her chibi “mochi mochi” form that it becomes her normal look.
This cute form helps her recover when she’s tired or in pain, almost like magic.
When the club does events like school festivals or café setups, Nonoa is a big help, making decorations and costumes.
She once made a Minecraft diorama chocolate for Toraji.
Despite her skills, she tires easily and often eats only omurice.
Friendship Growth and Moving Others
Nonoa’s lack of experience with friends makes her honest and direct about how she feels, which surprises and inspires others.
When Lilysa gets sick during a cosplay event and tries to take on all the blame, Nonoa finally shouts her feelings and asks Lilysa not to carry everything alone.
Her desire for closer friendship helps the group become even more connected.
She never really notices the romance among her friends and continues to see their interactions as just friendly exchanges.
Nonoa is sometimes used as a comedy relief in the manga, especially during changing scenes, where her chibi form acts as a form of mosaic.
She cannot finish a cup of bubble tea because of her tiny appetite.
Her mochi form is so famous that the manga’s creator has joked everyone can become "mochi."
In bonus materials, it is revealed that she has an older brother.
As of 2022, she has the fewest risqué scenes compared to other main girls, mostly because she’s always shown as a chibi.
Her favorite food is omurice, and she cannot eat breakfast most mornings because she’s weak and tired.
