http://www.mangago.zone/read-manga/tokyo_revengers/ it’s my favorite mangaヾ(❀╹◡╹)ノ~
You can read Gintama ^^ It's also a WSJ title so I don't think you'll be disappointed. Or One Piece!
Now if we leave the modern WSJ realm, then maybe Kemono Jihen, or Yu Yu Hakusho, or Nabari No Ou.
I'd suggest D. Gray-Man and Hunter X Hunter too, but they have irregular updates so that wouldn't solve the "not knowing what to read" issue...
Hmm I'll take this as a challenge then.
Shounen manga you haven't read... Maybe
07 Ghost
1000 Yen Hero (The idea is nice, the artstyle not so much)
Air Gear
Alive - The Final Evolution (borderline seinen)
Amatsuki
Ares - The Vagrant Soldier (oops that's a manhwa, but it's an old school one and really it's sooooo good once you learn to appreciate the artstyle)
Blood Lad
Buster Keel
Cagaster
Claymore
Dragon Ball
Eyeshield 21
Fullmetal Alchemist
Gamaran
Inu Yasha
Jujutsu Kaisen
Kekkaishi
Maou - Juvenile Remix (wait a bit for that one, chapter 6 and 7 are missing on mangago, we're scanlating them atm)
Mashle: Magic & Muscles
Nurarihyon no Mago
Pandora Hearts
Rurouni Kenshin
Superior (and its sequel Superior Cross)
Tegami Bachi
Trigun (and its sequel Trigun Maximum)
I hope you'll find at least one you haven't read in there ^^
As kimetsu no yaiba and nanatsu no taizai ended, I need new shonen manga to read. Any suggestion? (=・ω・=)
