I believe Amazon and Barnes & Noble are now selling eManga's through their apps (eg Kindle, Nook)
These are sites you can buy and manually add to your devices
>One Piece, Bleach, Naruto.
i just reread your post and i think you want a app like webtoon that you pay for the chapters,my mind went for free stuff because i never payed for webtoon's stuff just waited
if you want to pay for stuff: https://play.google.com/store/apps/details?id=com.vizmanga.android this is probably what you are looking for
there are companies that buy rights and translate manga,so official translation,and obv sell it for money.Biggest ones are:Viz,Vertical,Yenpress,Tokyopop,Seven Seas Entertainment,Dark Horse Manga,Crunchyroll(they translate manga too)
.A lot of them translate light novels too,don't know if i missed any.You can buy from them (places like amazon,bookwalker) and digitally read manga tho you probably know
some stuff:https://play.google.com/store/apps/details?id=jp.bookwalker.kreader.android.epub&hl=en&gl=US
https://play.google.com/store/apps/details?id=com.crunchyroll.crunchyroid&hl=en&gl=US
you might wanna search for yourself stuff like official publishers,manga apps whatever
also didn't wanna mention since they aren't "manga" but if you don't know theese for webtoon n all:
https://play.google.com/store/apps/details?id=com.tapastic
https://play.google.com/store/apps/details?id=mobi.mangatoon.comics.aphone&hl=en&gl=US
https://play.google.com/store/apps/details?id=com.qidian.Int.reader
they have same model as webtoon.2 are webtoon sites that people publish webtoons for (tho webtoon is the most popular place i think) and 1 is novels
again, if you aren't accepted on VIZ because of regions, there are 2 ways:
Just turn on VPN, choose VPN from US or Canada to be sure, and connect. Simple and easy. After finish reading, you can turn if off
So VIZ manga?
>Naruto Gaiden
Get VIZ Manga for that
