The Gunslinger Hero

Dressed as an outlaw to try it out for a costume party, Hunter though he was done with surprises after a certain event, but he now was summoned to a new world that praises three heroes, discriminates one, and is indifferent to him. He is acknowledged as a hero and is often thanked for his help, but people just see him as a normal person; just the way he likes it. However, they will find out that he is not a normal human.

Be prepared for some lemons. They will appear every so often. You have been warned.

I will warn you when they will begin so don't worry... Probably.
