I thought transmigrating was the limit, but I never expected to ascend successfully only to go bankrupt and end up drowning in debt. To pay the fines, I set off on a journey through other worlds. Completing the missions should have been a piece of cake, but I transmigrated to the wrong point in time. In Harry Potter, help! How do I avoid disrupting the timeline? I've decided to go with the flow. Wait, something seems wrong. I hope the missions can just complete themselves obediently. Hogwarts should give every graduate an award for outstanding achievement. Help! Can't they just pour the theory straight into my brain? (The first world is the Harry Potter era of the previous generation; the second is Jujutsu Kaisen. Later, I'll write stories set in other fanfiction worlds.)
