Bad news. It's canon.
! Chapter 402, page 2 (where he says he likes giraffes) and page 3 (where he speaks of their awesome power)– much of the rest of the chapter will spoil you for 287 it looks like.
Yeah, I figured it was. I just don't like it. And I've already seen 287 anyway.
BTW since I forgot to say before: good job catching up, ADC! If 287 comes out tomorrow like Wickio says, all that's left is 288 and the omake shorts. I'm looking forward to whatever you come out with.
