[Cosplay Transmigration] Cats Show the Way

A warning before you read: When the protagonist COSes while transmigrating, they'll do their best to keep things plausible. If you ask why, the answer is that the world's will makes it plausible. The protagonist has no CP. The author will try to avoid OOC. Bad ending.

The nine worlds are: Haikyuu!!, featuring setter Kenma Kozume; Demon Slayer, featuring the lonely demon Tanjiro who cannot speak; Tsurune, featuring the genius Nanao Kisaragi, who doesn't like making friends; Ace of Diamond, featuring the germophobic Eijun Sawamura; Gakuen Babysitters, featuring Ryuuichi without his younger brother; Kuroko's Basketball, featuring the smiling Kuroko; Hozuki's Coolheadedness, featuring the desireless Hakutaku; Katekyo Hitman Reborn!, featuring the daydreaming Tsunayoshi Sawada; and Hunter x Hunter, featuring a Gon with straight hair. There are nine worlds in total. Once they're over, that's it: there won't be any bonus chapters or new worlds.

I probably won't write anything particularly long, I think... The idea of writing two hundred or so chapters would kill me. It wouldn't be torture for the readers, but for me...
