What Am I Supposed to Do When Fights in Anime Worlds Can Only Use Domestic Kids' Show Characters?

Nohara Sumizumi is a goofy, lazy fish working in the Department of Two-Dimensional World Management, which exists within the three-dimensional world. To retrieve the 'pen' that keeps the two-dimensional worlds in balance, she sets off on a quest to find it. To fire her up for work, the bureau specially loaded character cards from the Flower Kingdom for her to use on her missions. They never expected her to be a master card-drawer, or that her talent for making things up would keep growing. Katekyo Hitman Reborn! world: As a beautiful sheep, even if I end up in a future war, I absolutely won't panic... Okay, maybe I will! Byakuran: I don't know whether you're panicking, but I'm definitely panicking because I've been forced to play pass the parcel. Demon Slayer: I've got experience now. Even if I show up as a snake demon in a world crawling with demons, I won't lose heart! Muzan: You're a born con artist! A big fat liar! You tricked me into thinking there was a Blue Spider Lily! Demon Slayer Corps: Cheng, you're an outstanding woman who never lets her disabilities hold her back! Bungo Stray Dogs world: As a bear, even if I end up in a world full of script maniacs... As long as I can't understand what you're saying, I'm invincible! The Bungo Stray Dogs cast: We've never seen a bear going around promoting "truth, goodness, and beauty." The list of characters getting picked on keeps growing... There'll be new anime and old favorites... Not sure about the pairing. Maybe one will emerge as I write. Either way, there'll be unrequited feelings! Warnings: 1. The order of the different worlds is undecided. I'll write whichever one inspires me. 2. Some original characters will get picked on. If you can't stand that, please scold me gently. 3. The timeline is a mess. Everything is in service of the protagonist. 4. If the plot has any logical issues, it's because the author is a novice. Please criticize me gently. 5. The characters will definitely be out of character. I'm truly sorry if that bothers you. Please criticize me gently. 6. Updates will probably happen whenever fate allows, dear readers. I started this without even having an outline, just writing for love of it and not thinking too much. When I run out of inspiration, I don't know how to keep going. Every time I open the document, my mind goes completely blank. 7. Quite a few people have asked, so I'll explain the blurb. My previous title used the term "Chinese anime." Since anime is a combination of animation and comics, and the two are closely related, Chinese usually refers to both together as anime. That's Baidu's explanation, and it's what the term means to me, though it may differ from everyone's understanding. So I changed it to "children's animation." Several readers said they'd watched the Chinese animations I mentioned, and I have seen them too. I just feel that if characters with very high combat power and ordinary human appearances enter these worlds, we'd miss out on a lot of fun plotlines. That's why I use animals so much.
