[Crossover] Conquer the World! My Harem!

Looking at the "main characters in my harem," for the first time in my life I felt the pressure of being a fan who loves everyone in fiction. I'm incredibly honored to meet you in person, but you've all transmigrated here, and Earth in the real world is under enormous pressure. There's no room for all of you! As an ordinary person who loves peace, how easy do you think it is to become a well-behaved, law-abiding citizen overnight to protect the peace of Earth?! What's with this ever-growing "harem lineup" that's absolutely capable of taking over the world?? (I just realized the title was too long, and the part shown on the homepage looked really weird, so I removed the words "reverse transmigration." Anyway, now that you're here, you'll understand.) Disclaimer: This is a thoroughly silly, Mary Sue story. I wrote it purely to relieve my recent stress and indulge my desire to pair my favorite characters with myself. The female lead may seem like a "men-all-fall-for-her" type at the start. The specific reason will be explained in detail later. Some characters who transmigrate from fiction may be somewhat out of character, but I'll do my best to keep them true to themselves. If you can't accept the above, please click the red X in the upper-right corner. If you ignore this warning and are shocked by the content, I take no responsibility. I never expected this story to become one of those "I'll finish it in this lifetime" projects, but I want to state once again that I won't abandon it. Updates may be slow, but I decided on the ending a long time ago, so I will definitely finish it. P.S. I'm eagerly looking for fellow fans of my favorite characters. Feel free to leave a comment and say hello XD.
