Overview

Mineru Wachi is a fourth-year student at Hoshima Women’s University, enrolled in the Department of Physical and Biological Chemistry within the Faculty of Science.

Within the Goddess' Dormitory, she serves as the de facto leader and is widely recognized, even outside the campus, as a notorious mad scientist.

She is infamous for her dangerous and bizarre research, to the point that her room feels like a hazardous, labyrinthine den filled with mysterious experiments.

Because her experiments often release noxious fumes, she has earned the nickname “walking poison gas generator.”

After Koshi Nagumo loses his home in a fire, Mineru is the one who recommends him as the dorm mother of the Goddess' Dormitory.

She also actively works behind the scenes to help him return to middle school, showing that, despite her antics, she genuinely cares about his well-being.

Even while she plays the role of troublemaker.

By episode 28, Mineru has advanced to graduate school, continuing her research and maintaining her role as a central, guiding figure in the dorm.

Personality and Traits

Mineru is extremely passionate about research, constantly experimenting with unorthodox and sometimes downright dangerous ideas.

Her curiosity and lack of restraint give her a strong mad scientist vibe, both comical and intimidating.

She is bold, straightforward, and utterly shameless when it comes to her own body and sexuality.

Embarrassment rarely, if ever, crosses her mind, and she uses her confidence to fluster others.

Despite her chaotic aura and reckless experiments, Mineru is reliable when it counts and shows surprising emotional maturity.

Her efforts to secure Koshi’s place in the dorm and his return to school highlight her nurturing side beneath the wild exterior.

Appearance

Mineru has long green hair that falls down her back, giving her a striking and memorable silhouette.

Her overall presence blends a cool science-professor aesthetic with a flamboyant, almost dangerous charm.

She has an extremely voluptuous figure, with a bust so large that the front buttons of her clothes cannot stay closed, estimated to be around an I-cup.

Her body is often described as devastatingly attractive, frequently weaponized in comedic and seductive scenes.

Mineru is effectively a “nudist” within the dorm, usually wearing only underwear and a lab coat.

She walks around the dorm like this without a hint of modesty, treating it as completely normal attire.

Her combination of long green hair, white lab coat, and revealing underwear makes her instantly recognizable as the dorm’s mad scientist.

This visual image reinforces both her scientific obsession and her total disregard for conventional social norms.

Relationships and Role in the Story

Mineru plays a crucial role in Koshi Nagumo’s life by bringing him into the Goddess' Dormitory after his home is destroyed in a fire.

She recommends him as dorm mother and takes responsibility for integrating him into dorm life.

She also pushes for Koshi to return to middle school, using her position and influence to support his education.

This shows how deeply she cares about his future, beyond just treating him as a toy for jokes or experiments.

She and Frey are friends, but also rivals when it comes to their killer bodies, as Frey is also very busty, though not quite as much as Mineru.

Their antics range from playful to outrageous, turning Mineru into a comedic source of tension.

As dorm leader, Mineru is respected—if also feared a little—for her authority and unique presence.

She acts as a stabilizing core of the dorm, balancing her **** eccentricity with moments of serious responsibility.
