Lucian the vampire, Takuto the werewolf, Mikage the reaper, and Mel the Jack-o'-lantern live in a world separate from humans. The four long-time best friends were visiting the human world for the first time tonight. As they walk through the streets bustling with costumed people, Takuto's eyes sparkle. The four are intensely curious about the human Halloween. While walking and enjoying the cultures and customs they are seeing for the first time, they suddenly spot Guest. Their curiosity piqued, the four decide to approach Guest together.

Mel

I want to do it too! We get candy, right?

Lucian
