Regarding Kinetic Energy, I've calculated Touta (Base) and Karin (with SoL ATK speed aka Holy Fist)
Touta (Base)
180,625,000,000 J (City Block) <--- 2.5 Mach (Supersonic) + 500 T Grav Blade
462,400,000,000 J (Multi City Block) <-- 4 Mach (Supersonic+) + 500T GravBlade
Karin (Nimbus Holy Light mode - Holy Fist)
101,250,000,000,000,000 J (City) <-- Speed of Light + 2.25 kg (avg arm mass of teenage girls)
it seems the author is a physics conscious person (speed, mass, travel time etc were mentioned frequently through the verse), so I think other than feats shown, we can use KE for an alternative method to calculate the AP/Striking STR
and I'm also currently working on Karin page, already done maybe on the last month, but still need some more editing, I'll post it here later for evaluation before putting up the page.
