These are official english translated series that are found on bato that are marked smut/hentai. If there a series that is official english but isnt marked as smut/hentai send me a message and I will add it. (not included are BL and GL they have their own list)
If I have add a series that not the official version or has unofficial and official chapters let me know and I will fix it.
(For more list go to My Hero Account. Which is a website that you can make list with links.)
