Yeah Gege saw that Horikoshi was ending MHA and was like "Yeah this dude is spittin!" Crazy to think that two major Jump series for a generation are ending. Meanwhile One Piece outlived Naruto, Bleach, Death Note, Sandland, Golden Wind - JoJolion, MHA, JJK, Reborn, Toriko and a whole lot more.
Glad Hunter X Hunter is coming back for a bit. I know Togashi has major health problems, so I hope he's pacing himself well, I'm guessing he'll do about 10 chapters so they can have a volume to release, I believe that's what he's done before. Or that, if possible, he'll have assistants helping as much as they can.
I imagine Jump is gonna try and find their next big series for a while Kagurabashi started out with Ironic popularity, but has gone legit, and Chainsawman is still kicking for the moment. Sakomoto Days is too, and I hear that the Rakugo manga is doing well.
Can't imagine how it'll go once Oda finished One Piece.
