Does any one know if Grell is going to reapear in the manga 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 مزید to it than that lol. It's not unlikely.

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

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

Pretty sure....
