The four basic forms of Shinigami combat.
- Zan: Zanjutsu (Swordsmanship)
- Ken: Hakuda (Striking)
- So: Hohou (Movement)
- Ki: Kidou (Magic)
Keeping these stats perfectly balanced (meaning that no stat is higher than another) is known as True Zankensoki.
It takes a considerable amount of work to use this effectively, as it takes considerably more time to train each stat effectively, and much practice (and strategy) to combine them into a formidable combat force.
