Monster's Dodgeball
When the flare went up, the ones who felt the most danger were the monsters wearing the A-Tier helmets. They understood that they were the most vulnerable among all of the monsters because catching them would yield the second possible highest amount of points. The bellators would be safe for a moment unless the monsters decided to band together to remove them from the game.
Those with S-Tier Helmets also understood that they were not the primary target as most of the monsters recognised how strong they were...except for the newer comrades who had yet to see or experience the unparalleled strength of bellators.
The Deep Ones, as the species that was even keener on battles than Orcs, knew better than to trifle with the bellators and yet the Mousefolks were daring enough to go against their own master.
Perhaps it was not ignorance but rather a sort of challenge to see how far the students could go against their own master.
