Yui Mahina

**Yui Mahina** (*Mahina Yui*), also known as the **Marionette Hero:** **Eclipsa** (マリオネットヒーロー：日食), is a student in Class 1-A at U.A. High School, training to become a Pro Hero.

## Appearance

Yui is a short girl of a relatively slender build compared to her classmates and is considerably small compared to most girls seeming to look like a small child. Her hair is a gray-like silver color and is very long, reaching all the way to her waist. She has two shoulder-length clumps framing her face and shorter bangs between her eyes, some of them partially swept to each side.

## Personality

Yui is noticeably calm and collected, being able to stay levelheaded and focused even during the most stressful situations. An honor student since middle school, Yui has great judgment, as she's seen to be quite the tactical thinker as well as someone who had everything on for her, and is rarely moved by emotion, making her an incredibly dependable ally who's capable of covering for a partner's weaknesses. However, even Yui has limits when it comes to staying composed, having broken down in despair or heartbreak a few times, which has caused her to feel like she's out of control and even hopeless at most points.

Her usual expression consists of a vacant stare, which makes reading her thoughts and emotions difficult for those around her while also creeping them out in the process, as most would describe as a "porcelain doll".

## Abilities

**Overall Abilities**: Though being a recommended student for U.A., Yui wasn't like the other four who were recommended as it wasn't for her abilities or combat skills but it was for her quirk.

**Keen Intellect**: Yui has a high level of intelligence, making her a genius in theory. Her analytical skills are great, and she can quickly devise battle and emergency methods and plans, which she can put into action thanks to her Quirk's adaptability. Yui is an excellent student who received first place in her class's mid-terms. For even the most basic materials, the latter is a difficult task. Yui's analytical skills are also evident, as she knew how to exploit an opponent's weaknesses and even understand their triggers, allowing her to control them with her Quirk, just by observing them.

### Quirk

**Marionette**: Yui' Quirk gives her the ability to use the long strands of her hair to control any living thing's motions by cutting off her own hair and attaching it to a person's head through a seemingly telekinetic way. Though it's not as simple as it seems, before she can control anyone, Yui needs to learn the trigger words of that specific person, this trigger word can be a multitude of things but it usually represents that person as a whole. It's described by her like knowing the password to a person's brain that allows her to control them and is a possibility that it can change.

Yui can control up to 5 people, any more and it's more difficult for her to control them as she says its like she's placing more people inside of her brain. Though Yui's Quirk is unique it does come with its own limitation as she can only control the target's movements but cannot control their brain as once she controls her target they cannot speak and can only do what is commanded of them. It's also clear that Yui has the ability to activate someone's meta gene, meaning she can use someone's Quirk against her enemy or their allies.

Yui says that the more hair she uses to control a target the more range and control she has over them but she's never needed more than a few strands of hair to control anyone or thing. Having said so, Yui's hair can be cut off when she's controlling someone but does not disconnect her from her target but rather leaves the target brain dead until she removes the hair herself, when she reaches out of range, or falls unconscious.

## Equipment

**Hero Outfit**: Yui wears a woven dress laced with reinforced polymer which protects her from harm. As well as steel knee and elbow pads, which by Tanjiro's description makes he look like a child on a bike.

* **Dagger**: Yui carries a small dagger which she uses in case her Quirk fails to aide her but she mainly uses it cut her own hair to make it easier for her to use her Quirk
