Touken Ranbu, but with a Beauty System

Well, Chi Youlin triggered the rule that cosplayers at conventions must transmigrate, but he wasn't even cosplaying! He was just carrying his sister's bag, and ended up transmigrating because he stepped through the convention center's entrance with his left foot. He was also bound to a Touken Ranbu makeup System… But he doesn't play Touken Ranbu, and he doesn't play dress-up games either. Completely in the dark, he still has to shoulder the task of keeping a small world safe and eliminating potential threats. The unscrupulous System says that if he fails his mission, it won't have enough energy to send Chi Youlin home. And so, muddled and clueless, Chi Youlin fights for the safety of the small world alongside his unreliable makeup System. What a touching story~
