Suddenly, a Skeleton Butler greeted the party before entering the manor… He spoke surprisingly polite for his intimidating appearance.
"Oh, but if it isn't Frank-sama and company- Oh? Could this lady be Kaguya-sama?" asked the Skeleton Butler.
"Indeed, I have come. It has been a long time, Sebas."
"It is a pleasure to know that Kaguya-sama remembers my humble name. Have you come to meet Clementine-sama?" he asked.
"Indeed, we came to meet her and her little daughter… and possibly the whole clan." Said Kaguya.
"Hoh? Is the proposal… That of war, by any chance?" asked the Skeleton Butler, his presence suddenly got way stronger out of nowhere.
Then, Frank realized that this Skeleton was actually…
A Peak Stage Demigod!
"(A skeleton?!)" he thought in surprise.
