Since I nominated it, I feel like I should probably try to gather some votes for One Piece, huh? But I'm on an extremely slow hotel WiFi, on my phone...
And it doesn't actually help that Monster is one of the best manga I've ever read. One Piece is "my manga" because I've followed it for half my lifetime, and I love it, but I'll be pretty happy whoever wins this one tbh.
I might make a case for One Piece once I get back to my own country and internet connection though, since Monster seems to be in people's favor atm and there should at least be some competition here.
