Is there a relation between Shigaraki's power and how many hands does it have in his body? I was watching a video of a Youtuber who covers My Hero Academia, and he made it sound like there is a relation between the amount of hands Shigaraki has attached to his body, and how much of his potential power he can release. 


   He mentioned he lost some of his hands in one of the last chapters of the manga, #chapter 238 apparently


Is there a relation between Shigaraki's power and how many hands does it have in his body?
In Chapter 222, it was mentioned that these hands somehow help Tomura Shigaraki calm down aside from making him nauseous. If I recall correctly, this was the only function it had and serve no other purpose to Shigaraki or his power. 

Some of these hands are recovered from Tomura's family when he accidentally killed them. The other hands from two unnamed street punks.
