Plot

Kouji Mikagami is a student who loves to play video games. One day, a priestess in another world named Zayd summons him, intending to recruit him as a soldier. When it is discovered that his ability is to temporarily copy other people's powers at lower levels, Zayd dismisses him as worthless and sells him as a gladiator, fully expecting him to die. In the arena, the losers are enslaved by the winners, with spells used to turn defeated men into women if needed. Realizing that this world works like a video game, Mikagami uses all his experience to win match after match, slowly building up a harem of defeated opponents as he aims to get revenge on Zayd for discarding him.
