I'm really interested in evil!Kid and how is he going to fight Spartoi, after all, we have never seen any "special" attack from Kid while he was fighting alone, only kicks, and how is going to react after the encounter.

Two words: Shinigami Chop.

or maybe, they're just lost.

If they're in the book, they're probably lost. I think it's more likely that they're not even in the book yet. Giricco probably decided to order pizza and then take a nap first. He'll get around to being a villain eventually. Maybe in the next story arc.

Thank you so much for your summaries, they always make me smile =D

Thank you, and you're welcome!
