The Wonderful Everyday Life of Ersi

After luckily winning a mysterious grand prize, at the moment his life went cold, he received a ticket to begin a second life for free. The System wouldn't say a word about its purpose, but it did offer an exchange: It could extend his life, in exchange for sending him off to be a fictional character without telling him a thing. System: You. Work. Got it? Protagonist No. 24: I do want to keep living... System: Great! I've prepared a body for you. Off you go! (decisively) It wasn't until Er Si arrived at his first destination and touched his long hair that he realized things weren't quite as he'd imagined. ...That face in the mirror looks familiar! Er Si: Tell me, are you obsessed with long hair? (speechless) System: I'm obsessed with long-haired beauties. (correcting him) (righteous) Main setting: His body is a copy of a certain character, changing with each world. ↑ He'll eventually return to his own body. A lighthearted story with no schemes. The System's setting is inspired by a certain coffee-pudding god's disaster. It has the style of a comedy manga, so feel free to close the page if it's not your thing.
