I've seen some APK in gamedva but I've never downloaded from them. I don't know if they can be trusted in general

says in the wiki it doesn't support comics or magazines. I'm guessing comics include manga in this case.

I didn't know it existed though, this is a huge help for ebooks so thanks for mentioning it. I'm setting it up now

I'll give Mylar a shot! Sounds like a good option, I'll play around with it to see if it works with Manga. Thank you

I'll check out Houdoku. If I can at least skip the part where I have to download to my phone first that'd be a big help. Thank you!
