It’s a reference to Dragon Quest VIII. I randomly came across the picture and was amused by just how nonplussed Rainbow looks by the presence of a low level slime on her head. Also I always liked the design of the clothes of the nameless hero of DQVIII.

Ah. Well, I hope you enjoy Book 2 as well. I know I had to do some shuffling around from the story's original content, but I just added a new chapter a while ago.
