Does any one know if Grell is going to reapear in the Манга again like in the anime?

He has already reapeared in chapter 55.

He was mentioned to have a new assignment dealing with the Phantomhives so it's possible. Also he's one of Yana's favorite, she's definably bringing him back.

I agree with vamp_grl_123.
Ronald mentioned an assignment Grell had dealing with the Phantomhive household, so... there's just not much еще to it than that lol. It's not unlikely.

I agree with emiliux123. He's there with Ronald Knoxx collecting souls from people eaten by zombies! Yay!!! Anyway Ты will be looking вперед to the point when Grell sees Sebastian is there! Like Grell says, the purest form of Любовь is a death match! XD

dont know but i realy hope he will!!!!

Pretty sure....
