Action

Lucien, who crossed over into the world of Harry Potter, awakened a strange Loan Magic System. With just a flick of his hand, he could borrow rewards in advance! Of course… debts still had to be repaid.
    Soon, the students of Hogwarts witnessed a newcomer who wasn’t only more talented than them, but also far more driven.
    [System Notification: Congratulations, host! You’ve obtained “Loki’s Faceless Mask.” Please repay your loan: Perfectly master Transfiguration.] Dumbledore: “Talent and diligence both in abundance… Could it be that Lucien is the true future of the wizarding world? But then… what about the prophecy?”
    [System Notification: Congratulations, host! You’ve obtained “The Complete Compendium of Dark Arts.” Please repay your loan: Deliver Voldemort’s head.] Voldemort: “What do you mean you’re in debt and need to borrow my head for repayment?!”
    [System Notification: Congratulations, host! You’ve obtained the recipe for the Resurrection Draught. Please repay your loan: Invent fifty entirely new potions.] Snape: “Lucien has discovered the formula for a resurrection potion? …Lily… Tell Dumbledore I’m resigning. Potions Master? Go find Lucien instead!”
