My Three-Day Sister

1. As a bizarre old monster who cultivated the Dao through poverty and became a god, and has no idea how many years he has lived, Ye thinks that if he stays this poor, he'll be done for sooner or later. 2. With a body type that makes every workplace he joins go bankrupt, Ye has had enough and simply opens a shop of his own. 3. And so, the Three-Day Sister Shop officially opens for business.

Blurb below: The Port Mafia thinks I'm a double agent sent to them by the Vongola, when in fact I'm a Vongola double agent sent by the Liquor Factory. The Liquor Factory thinks they found me by accident, when in reality I was raised by the Green Group from childhood. Everyone in the Green Group thinks I'm an ordinary orphan, when in reality I escaped from Gaozhi Yuzhuili's psychic research laboratory. The laboratory thinks I'm a weak test subject they're hunting down, when in reality I'm an unaffiliated Level 5 from Academy City. Academy City thinks I'm a psychic like that white-haired guy, with a good chance of reaching Level 6, when in reality I'm the Ultimate Heiress from Hope's Peak Academy next door. Hope's Peak Academy thinks I'm the first person to successfully skip school, when in reality I have the privilege of advancing at Hyotei without taking exams or even attending classes. Atobe's older brother thinks I ran away from home at three and became an all-purpose Mary Sue at five, when in reality I transmigrated here from the real world. I even have a game System. It thinks I'm a pure, naive sweetheart who knows nothing, when in reality I've had my future script ready since the day I transmigrated... What fun, all these layers of secret identities! But... sir, are you seriously telling me you've read a book and know my entire future script?! Someone get him! Drag him out and execute him! Boss Dazai: ??? It's a story of endless layers of secret identities, one on top of another, and there'll actually be even more than the blurb suggests... Please think of the protagonist as an onion spirit. Pairing: Boss Dazai. Theme: Family affection is something you understand as soon as you stand before someone, no matter how much time has passed.
