Honestly, life at the castle was hell, and it was because of three skeletons: Cross, Nightmare and Killer. Cross was weirdly obsessed with Nightmare, always calling him " senpai " , while Killer practically did the same, without the " senpai " and " kawaii " stuff.

Their dynamic was Cross and Nightmare always making out, while Killer was jealous and fought with Cross. . . That had to be the easiest way to describe it.

Cross was staring at Nightmare from afar, he appeared to be muttering " senpai " to himself. He also appeared to have a chocolate bar in his hand.
