Louis recalled the story of the puppeteer.
The puppeteer, jealous of his younger brother, transformed his own body into a puppet.
By giving up his human body, he reached a level that was previously unattainable and gained powers that transcended humans.
However, the puppeteer could not defeat his younger brother.
And the puppeteer left the academy.
He became a being that could not mix with human society, so he went into hiding in a place no one knew. It was a truly villainous end.
The puppeteer had a goal of defeating his younger brother, but he was unable to achieve anything.
