Dylan is going to be the cheekiest little dude. Unless he's in work mode, in which case, don't even talk to him. His face claim is actually art of Gin from Hotarubi no Mori e, probably the nicest little anime film I've come across. Very sad, but beautiful. I realise now that Ren kinda looks like the girl from HNME - I forget her name.

Also, Ren grew on the island in Japan that's full of feral rabbits. So that's a bit of trivia for you.
