Aquakinesis

Aquakinesis (アクアキネシス Akuakineshisu) is the Quirk used by Osen 
Description
Osen can control and freely manipulate water, and can she can create water from her body, like blood. After training, Osen is able to take in extra water, and store it within her own body, similar to that of a camel. In the cases, where Osen isn't near a source of water, and hasn't taken in any water, her body will begin producing the water it normally would, at a much quicker rate. 
Weaknesses
While Osen's ability to take in extra water, is very useful, there are still downfalls to taking it too much water. In addition to the 2.5 liters or 84.5 ounces of water, Osen normally drinks, she can take in about another 42-ish or 1.2 liters or water. If Osen is to take on too much water, she'll need to quickly get rid of it, or her body will naturally absorb the extra, and her body will go into a state where her skin becomes water, and she'll need to have her family use their Aquakinesis to pull the extra water out, put simultaneously keep her skin from ripping, and her bleeding, which if she were to the blood would thin in water, and she would die within a minute or so. This has never happened as, Osen is very careful with her body, and how much water she takes in.
