Kei Hada

REPLENISH

Kei’s quirk allows him to regenerate liquids and fine grains he comes to contact with with his hands. This ability, while simple, has many applications: refilling a glass of water, topping up a fuel tank, unlimited milk, you get the gist. His quirk works fastest with direct contact with the substance, the flow strong enough to propel it far before it experiences fall off. There’s also a small distance between his hands and whatever he wants to replenish that allows for his quirk to still work by holding on the item that contains it, perfect for when he doesn’t want to shove his hands in a bowl of hot soup.

As a side-effect, he can sense what a substance is made of once he touches it. This is only a vague idea though, as his knowledge is based on his own experience of what he’s already replenished. He won’t know something has vinegar in it until he can compare it to actually touching vinegar.

Due to this ability to tell apart components of a substance, Kei can target these specific parts instead of the substance as a whole. Most commonly he can dilute mixtures by creating an excess of water out of what already existed within it. In this way he can bypass the drawback of requiring exposure to the substance to replicate it at the cost of its integrity.

WEAKNESSES

Source: Kei needs a source to use his quirk on, he can’t make resources out of thin air even if it looks like he could. He needs at least one tablespoon of the stuff for his quirk to have any meaningful effect. He needs to stay in contact with the substance for the whole process, letting go stops it altogether.

Exposure: For his quirk to work, he has to have touched whatever he wants to replenish directly at least once, so his body absorbs and learns of its genetic makeup should he want to duplicate it in the future. Even a slight difference is enough to be considered "new" to him, he’s dipped his finger in several brands of soda that taste the same save for some ingredient that can’t be pronounced. This requirement bars him from replenishing dangerous substances like corrosive acids and toxins as he doesn’t hold any immunity that would protect him. He’s also unable to duplicate anything he’s never had direct access to, and given that he’s only a student, he doesn’t have access to a great many things.

• The only exception to this is if Kei targets part of the substance instead of all of it. As long as he's had exposure to the one part, he can replenish it, though the solution as a whole would change because he increased the concentration of the one part.
• It takes precision though. Given that this is a new ability Kei's learning to use, he can only do this if the component makes up at least 50% of the mixture.

Viscosity: How well his quirk works is entirely based on how thick the solution is. Free-flowing liquids like water are fine for him to replenish and is the fastest for him to reproduce, but thicker substances like honey take more time and energy to produce more of. The thickest substance he can replenish is chocolate syrup (25,000 cps, the unit of measurement for viscosity), anything thicker takes so long to create and so much of his stamina that using his quirk on it is not worth it for him at this stage.

Energy usage: Creating those resources seemingly out of thin air does take up his energy. While the amount of energy is negligible when refilling a drink, continuous usage gives him symptoms of low blood sugar like lightheadedness, fatigue and anxiety. Tremors start to set in after five turns of constant use of his quirk with his support gear or when he just needs to generate a lot of something, after which he has to rest for two else he’d risk passing out.
