"The nature of Mitori's abilities are yet to be revealed, but what is known is that she is capable of using a liquid metal to control a copy of herself. This clone is capable of manipulating its body parts to create weapons which can be as sharp and agile as a butterfly knife, and can withstand electric attacks and having objects teleported into it. However, it appears that the clone dematerializes into a puddle when Mitori goes too far away from the clone."
