I, Aoki Chie, was the life, relationship, and psychological counseling mentor to the demon king Muzan in the Taisho era.
An accident, and that little brat Muzan dragged me into his mess.
I fell into a deep slumber.
When I opened my eyes again, I was in Tokyo.
I planned to live a normal life
and enjoy a comfortable retirement.
But I never expected the shop to get blown up on my very first day in business.
Or for the streets to be thrown into chaos on my first day out shopping.
The culprit was a handsome white-haired young man with glasses.
He seemed to have crossed paths with my unfilial disciple, Muzan.
I was very interested in the young man.
Relying on my connections built up over many years,
I became an acting homeroom teacher at the technical college.
I thought that after living this long,
I could bring this white-haired young man to heel in no time.
I never expected him to be no cute puppy at all. He was completely unhinged, and nearly brought down the world.
Note: Gojo Satoru is the pairing. The timeline is when Gojo Satoru is attending the technical college.
The worldbuilding is chaotic, with all sorts of characters dropping in.
Premise: Youth is living with carefree abandon.
