Collapse

Nanami's Ratio TechniqueRatio TechniqueInnate TechniqueEverything has a weak point at the seven-to-three ratio. Walls, cursed spirits, human bodies, barriers. Nanami identifies the line, marks the spot, and hits it. His strike at that ... identifies a weak point at the seven-to-three ratio on any target. Collapse takes that concept and concentrates it into a single maximized hit, all the force directed precisely at the structural flaw, creating an implosion at the point of impact. Think of it as the difference between tapping a crack in a wall and driving a sledgehammer into it.

Nanami used Collapse sparingly. It burned more cursed energy than standard Ratio strikes and required precise calculation. But when defenses were too thick for normal attacks, concentrating everything into one perfect hit at the exact weak point usually solved the problem.
