Karasuba: Hypersonic + able to outrun, bullets, tank fire, machine gun fire, anti aircraft rounds, etc. DC: Multi City + via powerscale maybe higher. Karasuba has killed an entire army with tanks, and helicopters all singlehandly and an Army with jets, helicopters, Submarines, tanks, etc with Miya, Kazehana, Matsu, Mutsu, and Yume.
I have to go by Manga and Anime because, Karasuba's feats can't be found anywhere.
Fight takes place in Tokyo
Video is to show how fast Karasuba and the other sekirei are.
Everyone is has access to all of their abilities. Karasuba without Norito
