[Haikyuu!!] Miss Kato Is a Villainess

(Read the summary three times before starting. Read the summary three times before starting.) Weibo: Today's Coco doesn't want to update either. Purple Eel: Weird and Wonderful Rococo. People call women who are vicious, capricious, spoiled, unreasonable, and two-faced evil women. Kato Mari is an evil woman. Miss Kato has this to say: “I'm just a carnivore, that's all.” The men and women she's tormented: “Ah... in a way, that's true. You are pretty carnivorous.” Beautiful and charming, with a nasty personality. The main storyline is volleyball. The story is made up of episodic arcs, with crossovers featuring some other manga and anime. The timeline is set after everyone is an adult. The heroine is five years older than Hinata, so she's older than all of them. Everyone starts out with 100% affection for her. No one can resist Miss Kato. Number of people she torments: probably over twenty... Content warnings: 1. This isn't a one-on-one romance. Pure-love fans, take note. 2. The timeline is after everyone has become an adult. Their personalities may differ somewhat from their high school selves, and the premise makes OOC moments likely. 3. The heroine is not pure, and she's a heartthrob with many admirers, both men and women. Readers who prefer pure, devoted romance should be cautious or avoid this. 4. The endgame partners are already decided, and there are multiple people. You can guess who, but I won't change it or spoil it. Happy ending, everyone is happy. 5. I don't deliberately vilify any characters. People have endless potential, so please understand. If it feels like vilification, just consider the novel seriously OOC. 6. The heroine does whatever she wants. She's just as her name suggests: an evil woman. She really, really, really is wicked and charming, and there really, really, really are a lot of people (important things said three times). 7. If you like bad women, you're very welcome here~ I've said enough about the warnings. Any more and it would be rude. Theme: I write to relax.
