A Threat

Due to the recent incident with the double event of the Dungeon Spire and the Dimensional Portal, most agencies closed down for a few days just so everyone could focus on trying to clear the dungeon.

While Tatsuki's party is the main one, they weren't the only ones tasked with clearing the dungeon. In fact, most agency heads have been assigned a party to which they'd go in succession so the dungeon clear would be as efficient as it could ever get. Tatsuki's party would lead the expedition on the first day and as soon as they returned to the surface, the next group would then proceed where they left off. After that, the next group would then go until the lengthy round-robin was finished. By the time it reached back to Tatsuki's party, they'd have plenty of rest and will be ready to go to the next floors, starting from where the others had left off.
