Character Setting

Edit

Uta Koizumi is an 11-year-old girl from Miyagi, Japan. She is known for her long career as a child actress and is trying to find a new path by becoming an idol. Even though people often call her “sensei” because of her experience, she is actually the youngest among the main contestants. Uta has a strong will and high pride, but deep inside, she wants to show her true self and not just be seen as a child star. Her love for trivia, reading Wikipedia, and watching popular anime helps her dream big and set new goals.

Her body measurements are B72, W52, and H73.

She has blood type B.

Her birthday is November 7.

She is in the 6th grade of elementary school, making her 11 years old.

Uta is confident, hardworking, and proud of her achievements, but she also has a side that wants to rely on others and show her feelings.

She is careful about her image and always tries to act responsible.

She is curious and loves learning new things, which makes her an expert at trivia.

Uta enjoys reading Wikipedia and watching anime, which are both her hobbies and help her improve her acting.

Uta started working as a child actress at the age of four.

She became famous for starring in TV dramas, and many people know her face from acting.

Even though she is experienced, she sometimes feels trapped by her “child actor” image and wishes to try new things.

She decided to become an idol to break free from this image and to discover her true potential.

Uta is talented in both singing and playing the guitar, although she kept these skills hidden for a long time to protect her image.

She quickly learns new things and is excellent at memorizing details, thanks to her love for reading and anime.

Uta formed “GAPsCAPs,” a music unit, with Mako Toma and Shiori Yamaga during the first selection round of the Selection Project.

Uta plays guitar for the unit.

Because of her long experience in entertainment, the others call her “sensei.”

She sometimes clashes with Shiori Yamaga, who is also proud and competitive, but together they learn to work as a team, thanks to Mako’s guidance.

She talked to her mother when she was wondering if she could try being an idol, but her mom first said no.

Eventually, her mother supports her new dreams.

Facing Her Rivals

Uta joins the Selection Project as a representative from the Tohoku Region.

She teams up with Mako Toma and Shiori Yamaga and forms a live music unit called “GAPsCAPs”.

Although Uta is experienced, she has to work with others who have strong personalities, which leads to arguments, especially with Shiori.

Overcoming Doubts

People expect her to act like a perfect child star, which causes Uta to feel pressure.

One day, a driver mentions that she “could be an idol,” but her mother quickly brushes it off, making Uta feel unsure about taking a new path.

She struggles with whether she should break away from her old image.

Proving Her True Self

An accident happens before a live TV show where Uta is supposed to appear to promote a drama.

The person who was meant to play the guitar for the main theme song gets sick.

Uta decides to step up and use her secret guitar and singing skills to save the show.

Everyone is surprised and impressed by her hidden talents.

New Beginnings

After the event, Uta’s mom tells her that everyone loved seeing a new side of her.

Uta gains the courage to show her real self and decides to let the world see all of her talents.

She starts to pursue her dream of being an idol, not just as “the child actress,” but as Uta Koizumi.
