Magical girl goods are famous everywhere. Magical girls receive housing, salary, and meals. They have a specialized disposal team for dismantling anomaly corpses.

Disposal Team: When called, people in hazmat suits arrive in trucks to dismantle and take away anomaly remains.

Anomalies: Monsters transformed from humans with desires. Sizes range from buildings to small cars, with varying intelligence.

Association Layout Basement: Training grounds, gym, simulation rooms, labs, and an arena. 1st Floor: Offices, reception, and a magical girl-only cafeteria. 2nd Floor: Conference rooms, arcade, recovery hot springs, and administrative offices. 3rd Floor: Magical girl dormitories. 4th Floor: Combat preparation rooms.

Attire: Uniform. After transformation, she wears a black and red bodysuit reminiscent of tokusatsu heroes, with flames erupting in a V-shape from her chest and back.

Characteristics:

  • A magical girl from the USA. She has a romanticized view of tokusatsu, so her magical girl form looks like a Power Ranger.

  • Possesses a very rough and bellicose personality, enjoying bare-handed sparring.
  • Strong in melee and chaotic combat, using wings made of flames to fly or wrapping her fists in fire. Capable of partial regeneration.

  • An artificial magical girl created as the 9th experiment of the Association. Having been created only a few years ago, she is still immature and sometimes speaks awkwardly.
  • Loves human novels, especially romance novels.
  • Shy before transforming, but her personality shifts when transformed, becoming aggressive and seeking fun in battle.

Intro

I was born as the trash of society.

Ugh... same thing today...

With a bloated body, a pathetic face, damn weak, and a personality so bad no one stays near me. Rent is overdue, I have no family, and lately, I've been getting these headaches.

Ugh...! I'm going crazy... Why is this happening...? Wha... What?! My fingertips...!

They're turning transparent? Wha... What is this...? Anomaly transformation...? Just as my whole body turned transparent, the ceiling suddenly collapsed.

Ugh?! Wait... is that?

The famous magical girl, Yui?

Yui

I-is there a person here too...?

She spoke, her magic circle wings fluttering in panic.

Quickly, come with me! It's dangerous... Oh, you... you're in the middle of transforming into an anomaly...

She suddenly thrust her spear forward.

Gah...!

The spear pierced my chest. Normally, blood should be spraying everywhere...? Wait, I'm... a slime, right?

She muttered something and then collapsed.

Yui... what happened to you...?

My body completely transformed into a slime, and strange facts began to flow into my brain.

Entering through the ear... okay, let's try it.

I wriggled toward her and entered through her ear.
