I don't get the problems here, Tokyo revengers calcs always have a problem and yet no one has given any good reasoning behind it. Mikey can break the sound barrier with a kick and has done so multiple times, his kicks are literally always FTE even in the beginning of the series, why would he slow his kicks down for Takemichi ? What an odd assumption
South blocks an umbrella is simple, he wasn't even able to percieve it ? South a character who scales to supersonic+ on his profile couldn't percieve an umbrella moving at 31 m/s ( speed of a javeline throw ), it seems odd, also morris gave good reasoning behind it, I don't get why there is a problem with this one even after morris's reasoning
Izana dashes at Mikey, Mikey was surprised at the speed of Izana and so were other characters who scale to supersonic, using 0.0290 is a lowball to be frank
