Ayame in fruits basket ヾ(❀╹◡╹)ﾉ~ tho he doesn't appear much in the story he still has my heart. Even the few panels with him are fine.
I have yet to read the manga so not sure how he is like in that but he's perfect in the anime.
I also love snakes.

Snake boys! Snake girls! Amiright?
Please give me some manga with snake or snake-like MAIN characters.
Snake powers? Perfect. Slit tongue? Perfect. Slit face? Perfect. Snake-like personality? Perfect. Pet snake? PERFECT.
Anything goes. Action, romance, horror, anything. Preferably manga, but manhwa/webtoon are also fine
