Finding new legal manga releases online in English is sometimes complex, since the big name publishers offer their series on various online services. Most people will pay to support their favorite artist and series though! Here’s a list of simulpub manga and where to find them~
I’m including only websites/services that offer simulpub (released on same day as Japanese or up to a week later). They are: Weekly Shonen Jump, Yen Press Digital, Kodansha Comics, Crunchyroll Manga, Manga Box, ComicWalker, and Comic Zenon International. The series that they host are listed below the cut!
