Every cut in Samurai Quest is judged on three action-virtues at once, not three separate rules:
義 Gi
Direction. Cut from the correct angle — happō-giri, the eight-direction form. Wrong angle grades as a miss.
誠 Makoto
Power. Tenouchi — real blade speed at the moment of contact, the difference between a good cut and an IPPON.
礼 Rei
Follow-through. Zanshin — sustained awareness after the cut, read in the HUD as a combo aura that escalates toward gold.
