Author note:  this is a fresh new story. I still haven't thought of a name for the main character. For now I have a placeholder [MC] until something catches my eye. After completing 100% got all achievements in Simulation World. [MC] goes to bed only to find he has been summoned by a priestess needing his help. She summoned him in an emergency summonig to stop evil beasts that look like her created in Simulation World. He is quickly ditched by the priestess after his classes and skills are inadequate to her approval. He is then left to fend for himself as he unlocks his 2 classes. Cheater and Modder. With his 2 classes he can alter/buff his own body with "cheater" and alter/mod the system with "modder".  Although, every power comes with a price. Ceatain modifiers will only trigger in certain situations. He also has to type in a terminal for modder or using the Komani code for cheater.
