The relevant settings and characters in the anime "Bleach" are referenced! But basically it is still my own original work. When Pangu first created the world, he divided the material world into six parts. They are: God Realm, Demon Realm, Soul Realm, Demon Realm, Underworld and Human Realm. The six realms have always been in a certain state of balance, with no contact or disturbance to each other. But suddenly one day, this balance was broken, and things happened one after another.
