Kidō

Kidō (鬼道: "demon way" or "spirit way") is a form of Shinigami combat based on advanced spells.

Overview
These spells are produced with strong Reiryoku and fall into two categories: Hadō for direct attacks, and Bakudō for battle support. It is one of the techniques in the Zankensoki, the group of Shinigami primary combat skills. Kidō spells are triggered by an incantation. Experienced users can trigger them without an incantation, though the effectiveness of the spell will be diminished.
