Though it doesn't have an official name yet, basically every Quirk name (with one exception, I think) has been in noun-form in the original Japanese. So it would probably be okay to have the Japanese as 巻き戻し -"makimodoshi" the noun-form of the verb "rewind". I've seen people doing that on Japanese sites. Right now there's just a description of what it does, rather an actual name.--Rrmcklin (talk) 00:36, July 2, 2018 (UTC)
Didn't Neito Monoma say that Rewind is a Accumulation type Quirk?
