@Galenbeta: Sebastian is supersonic+.
Current Tsunade is hypersonic at least by powerscaling. She's going to reduce him to a bloody stain on the ground.
He's hypersonic+. Specifically mach 10 at the bare minimum.
Though I doubt having the speed advantage in CQC is going to give him the win against an endurance tank like Tsunade (who can also arm herself with regen).
@phantomrant: Woah nice.
Kuroshitsuji didn't seem to get too much attention in OBD so i assumed there never were any calcs for it. It being a setting with rather old ass guns and most feats being plain bullet timing i assumed that supersonic+ is the top.
Now such a speed upgrade is really nice. Wonder if anything like that came up in the latter chapter.
He still loses tho, but thanks for the link.
