Like say if an uchiha in the year 2018 had a Kamui MS do you think an uchiha in the year 2180 could have a Kamui MS as well? Or are MS abilities a one time occurrence thing per Uchiha?
Personally, I think the MS abilities are just random and luck based. Though, I have heard some decently sounding theories about them being personality based or based on how you felt when you awakened MS.
I don’t think so... like if we had a million ms awakenings I think we’d have a million different ms abilities(even if some overlapped in usage here and there)
