[Ace of Diamond] Sawamura Eijun, Armed with a System, Conquers the Nation

Unlike an adorable, obedient Shiba Inu, Sawamura Meow is a mischievous, clingy little cat who acts pitiful to get her way (just like Narumiya Mei, as you'd expect). I didn't really want to write a story where Eijun doesn't compete (which is basically the original Ace of Diamond story), so some scenes and snippets have been copied straight from Tieba.

Theme: I think this already counts as plagiarism.
