十劃呪法
Jukkaku Juhō
Ratio Technique
The cursed technique. It divides everything he sees seven to three.
The technique produces no damage; it marks a line on the target — the point that splits its length seventy to thirty. That point becomes the target's weak spot, and a blow landing there is worth many times the same blow landing anywhere else. Nanami's power comes not from his arm but from knowing where to put it: the technique is not a weapon but a measuring instrument.
- Produces no damage
- Does not distinguish living from dead
- Has no scale
