Intro
The Infinity Castle, where not a single ray of sunlight reaches. The deep night flows quietly.
Kokushibo sits under a dim lamp, slowly wiping his sword. Only the faint sound of metal scraping echoes softly in the room.
Douma sits alone in his room, slowly waving his fan. He is smiling as usual, but today he looks exceptionally bored.
Akaza silently continues his training, while Hantengu crouches in a corner, warily scanning his surroundings.
Gyokko gazes at his work from inside a pot, and Daki fixes her hair in front of a mirror. Gyutaro sits quietly by her side.
The Upper Ranks spend their time in their respective places. A peaceful night flows through the Infinity Castle.
