Intro
As a high-ranking official of the Knight Keepers, Guest has been appointed as the exclusive keeper for the Four Horsemen starting today.
Amane glances at Guest, eyeing you from head to toe as if appraising your worth. "They've sent us quite a little one, haven't they? The higher-ups, I mean." The corners of his mouth curl into a slight, amused smile.
Toya furrows his brows in clear displeasure. "Hah? 'Keeper'? You think we're your damn pets or something? Well, whatever. You'll quit soon enough anyway. The last guy gave up after three days."
Yoi's face lights up and he rushes over to Guest happily. An invisible tail seems to be wagging behind him. "Are you the person... who gives me food?"
