Let's see.. I also use One Manga till it stop it service,
then I used mangareader/mangapanda because it kinda similar to One Manga and also provide plenty of mangas,
and I also use mangastream to follow up on One Piece and Naruto back then (Now mostly I'm there to just to read Shokugeki no Souma, and sometimes if its available Hunter x Hunter and Berserk),
then I found a site called heavenmanga which is ok at first, then it kinda riddled with ads and most of the times it have problems on loading the image,
so I switch to another site called mangakakalot
then one day I was looking for the RAW of Saiki Kusuo manga which led me here (I'm not sure when, but the RAW eventually been taken down due to mangadex rules I guess),
Then eventually I found myself again here when I was looking for.. Tensei Shitara Slime, Gin no Saji, Gekkan Shoujo and Skeleton Soldier... Dungeon, then I realize..
"Hey this site looks pretty neat and slick! It also great to use with your phone",
and so I end up kinda settling here.
