After traveling to the world of the God of Death, he became the younger brother of Kadori Tokusai.
He thought he had a big thigh to hug, but he found that Kadori Tokusai didn’t have many years to live.
After Kadori Nanyue became the swordsmanship teacher of the Maou Spiritual Academy, he awakened the teacher system and became stronger by teaching.
In order to find a way to cure Kadori Tokusai and to have the strength to gain a foothold in this world, Kadori Nanyue worked hard to teach and become stronger.

However, isn’t the feedback reward for teaching disciples a bit strange?
[Rokuguruma Kensei’s strength has greatly improved under your teaching, and he has been rewarded-Special Kidō: I won’t waste too much of your time! ]
[Aizome Sosuke’s strength has greatly improved under your teaching, and he has been rewarded-Special Kidō: Hairspray Hand]
[Kurosaki Ichito’s strength has greatly improved under your teaching, and he has been rewarded-Sacred Word D: What are you… talking about? ! ]

Many years later, Kadori Nanyue has enough strength to gain a foothold in this world, and wanted to stay behind the scenes and live a leisurely life.
As a result, one day his disciple Aizen Sosuke came to him and said,
//The vacancy of the throne of heaven has lasted too long. Please end this unbearable vacancy!//
//From now on, it will be you who will stand at the top!//
