Yoneda Kou for creating realistic characters.
Junji Ito for his accomplishments in the horror genre.
Tsubaki Izumi for poking fun but also respecting shoujo tropes.
Shirahama Kamome for gorgeous drawing techniques.
ONE, much respect. A humble webtoon artist with an amazing imagination.
My favorite mangakas. Ongoing list. http://www.mangago.zone/home/mangalist/269274/
Hands down: Nishida Higashi. I've read sickness in youth about a 1,000 times. She is is the queen of sexual tension. For horror/gore Nishin Masumi.
i'm just wondering, because i was thinking about it myself. my favorites are definitely zariya, harada, ichikawa kei, tirano kim, and fujoking. who's your favorite?
