Character Setting

Edit

Matama Akoya is a recurring character from the manga and anime series Gushing over Magical Girls, a wannabe idol and member of the villain organization Enormita who transforms into the combat form Roco Musica.

Name: Matama Akoya

Gender: Female

Age: 14

Birthday: April 8

Favorite food: Sweet rolled omelet

Disliked food: Coriander (cilantro)

Recent ambition: To upload singing videos to social media and go viral

Affiliation: Enormita (formerly the Lord Squad under Michiko Tanaka)

Magical form: Roco Musica

Voice actress: Yuuka Aisaka

Akoya is a loud, confident, and selfish girl on the surface, but underneath she is sensitive and easy to make cry.

She has dreamed of becoming an idol since kindergarten and joined Enormita mainly as a way to chase that dream.

She is stubborn and quick to argue, especially with her childhood friend Nemo Anemo.

At the same time, she has a surprisingly serious side when it comes to her dreams, fashion, and relationships.

Akoya used to belong to Michiko Tanaka’s Lord Squad and initially fought against Utena Hiiragi’s group.

After repeated clashes and punishments from Michiko, she eventually defects and joins the side of the Magical Girls.

As Matama Akoya, she is a tall and glamorous-looking 14-year-old with a very curvy figure.

Among the girls her age in the series, her bust size is described as top class.

Her hair is a brown tone close to red bean color, reaching to just above her waist and styled in a two-side-up.

She has greenish light blue streaks (mesh) in her hair, giving her a colorful, idol-like look.

Her face is a bluish green tone with pink-highlighted eyes, and she has noticeable cute fangs.

The overall impression is flashy and eye-catching, fitting a would-be idol.

School Uniform and Casual Clothes

Akoya’s school uniform consists of a blue jacket, a mini skirt above the knee, knee-high socks, and a large red ribbon on her chest.

She goes to the same school as Nemo Anemo, which is different from the protagonist group’s school.

Her casual fashion usually features short skirts and exposed shoulders or legs, hinting at her interest in stylish and slightly revealing outfits.

She cares a lot about clothing, as seen when she is excited about idol costumes and swimwear choices.

Roco Musica is the transformed form of Matama Akoya.

In this form, she uses her voice as a weapon, turning her songs into musical-note-shaped shockwaves that attack her enemies.

Her star rating as an enemy is three stars.

Originally, Akoya wanted a traditional cute idol outfit for this form.

However, Michiko Tanaka insisted that subordinates must have a form suitable for her vision as a “lord,” leading to Roco Musica’s current more revealing, villain-style design.

Later on, her transformation develops the special (and embarrassing) feature that her underwear automatically disappears when she transforms.

Roco Musica’s weapon is a condenser microphone with a cross-shaped star called Voix Forte.

She uses this microphone both as a symbol of her idol dream and as a magical weapon during battles.

Akoya’s biggest dream is to become a popular idol.

She writes and performs her own songs with total confidence.

Her signature original song is titled “L.O.V.E-ly Roco” (romanized from her own clunky naming sense).

The lyrics are painfully uncool, and her baseline singing voice is so awkwardly off-key that it leaves listeners completely expressionless.

The running joke is that her singing is just bad enough to be uncomfortable, but not bad enough to mock without feeling guilty.

If someone directly criticizes her singing or lyrics, she tends to burst into tears.

Shame-Powered Singing

During a battle with the Magical Girls, Akoya discovers a bizarre ability.

When she is forced into a humiliating situation—such as singing while naked—her singing voice becomes incredibly beautiful.

In that scene, she is taken hostage along with Nemo Anemo, and Akoya is made to sing naked in front of others as a form of humiliation.

Overwhelming shame triggers a temporary dramatic improvement in her singing, moving listeners despite the lyrics being unchanged.

This leads Akoya to realize that exposure plus embarrassment dramatically boosts her vocal performance.

Even going without underwear improves her singing to some extent, but the effect is strongest when
