I Became a Swordsmanship Instructor at the Academy

Unexpected luck that came after my death, which was unlucky in my life.
When I told King Yeomra, ‘I want to live in a world in a novel’, it really came true!
The main character of the novel is the 3rd generation conglomerate of the Hunter School, an immature idiot.
By the way, is there anything strange about my reincarnated appearance?

[(Web transmission) Hello. Shinhyuk Kang. You have finally passed the hiring of a swordsmanship instructor at the 1st Hunter School you applied for this time.]

‘why… Am I not the main character?!’

I became a supporting character among supporting characters in a novel, a swordsmanship instructor at an academy.
