Not surprising at all, two of the humans were Lucius and Mersey, the leader of Earth Shield and, respectively, the President of the Academies Association.
Lucius's ability was just as everyone expected: a shield—a fitting ability for someone who started such a faction.
As for Mersey, he was lucky enough to get an attack-type ability.
The two were currently back-to-back, with Lucius blocking every single incoming attack, even if the Ten Families did the same fused attack like Lancelot did with Lydia.
Sierra was a beautiful blue-haired woman with crystal eyes and a heightened battle sense; she was capable of fighting over fifteen enemies by herself, even more than her father.
Her Water Monarch Ability could perfectly use the oceanic water in her favor to attack the Ten Families' members from any position—or block, for that matter.
Arthur and Ariana were also doing decently against their enemies; the duo's synergy seemed to be something else.
