One day my dream will come true and I will become a Warrior of Light, and my hard and happy harem life will begin! Writing for the sake of writing... The protagonist is an uneducated person who travels to a world where there are arcades to play one day. However... Let me first destroy the subjective world of concave and convex man fighting each other. This novel and its characters are purely fictitious.
