This topic is created with the BIG help of this shared information.Kidou, also known as Demon Arts, is a form of magic used by Shinigami during combat.
There are 3 types of spells:
Bakudo, or Way of Binding;
Hado, the Way of Destruction;
Kaido, better known as healing Kidou (never described in either the manga nor anime).
Spells go from number 1 to 99, their complexity and effectiveness increasing with both their number and the caster's own power.
I've only written down the spells from the manga, so there won't be some of the spells found in the fillers.
