Reincarnation Colosseum – Using The Weakest Skills In Order To Defeat The Strongest Women And Create A Slave Harem

Story:

Hardcore gamer Mikagami Kouji is a typical high school student. One day he gets isekai'd and all he gets is the seemingly worthless talent "copy," which we all know is actually OP or whatever. His summoner, the large booba head priestess Zayd, has sold him into slavery to serve as a gladiator. If he loses his fight in the Colosseum, he will be sexually assaulted.
