One Piece, Naruto, Bleach, Hunter x Hunter, Hitman Reborn & D. Gray Man. They were coined because for a year or two they were the smashing success of jump. Now it's pretty much just OP. Naruto dropped but is still big. Bleach, eh. And HXH depends on whether volumes get released or not. KHR was ended early and D. Gray man was moved to monthly jump and has been on a hiatus for 17 months.
