Sakon maintains that Kisaragi is innocent and identifies significant tensions among the museum staff, noting the director's unpopularity. He requests Kaoruko to postpone the arrest for 24 hours, allowing him sufficient time to prove Kisaragi's innocence. This delay is intended to facilitate a thorough investigation into the circumstances surrounding the case, as Sakon remains convinced of Kisaragi's lack of guilt despite the prevailing suspicions. The narrative focuses on the procedural steps taken to verify these claims within the limited timeframe provided by the request.
