Right. Especially since Kira's best at close ranged, so, even Valentine taking out Kira is something I personally can't see happening the majority of the time. I've done the math, and Kira should have a reaction speed of anywhere from 63c to 181c ( Though, these calcs are the absolute BEST for Part 4. Considering said calcs are coming from Kira getting blitzed, the actual result is likely lower than this ). I don't remember what multiplier someone needs to blitz a person, so that's part of why there's a huge gap.

A number followed immediately by "c", at least in VS terms, means it's that many times the speed of light. Valentine, and the SBR verse as a whole, doesn't have any light speed, FTL, or MFTL reaction feats. ( And as someone who absolutely loves JoJolion, this sucks like hell. ) Even if we assume Valentine has a reaction speed on par with DIO/Part 3, which is either 632c or 1265c depending on if you accept the low or the high end, Part 2 and 6 are likely much faster than it. Very possibly, both could blitz Part 3, even if 6 is the only one we could get hard numbers for.
