[@Ryonara] The problem is almost all Quirks come with some form of Backlash in MHA... even with that solution, he still can technically use his quirk indefinitely. Not that it's the most OP power I have ever seen, but it's more in order to follow the MHa spirit? I'd rather see a upgraded version of the Quirk with some sort of limit to it, than a weaker version with no limits, if you understand me? 

[@Aerandir] I forgot you ! Haha. So far it looks ok, but I will wait for a finished CS before judging.
