Mythical Beasts and How to Capture Them

There are magical creatures that roam the world. They harm many humans with little to no restrictions, with the only few being able to fully destroy them being Angels, Demons, the gods of Destruction and Creation, and any human with powers. All of those go to a school to learn how to use their powers as a good thing, how to control them and either go on as a regular human or to be... super powers. In that school there are things going around but we aren't telling the story of them. The few gods of Ancient Egypt, Rome, and Greece have come together to create the Hunter for the creatures, their name? Ruby. She has powers that the Vanguard students would have, along with the gear needed to capture the beasts. That being a pistol that shoots glowing blue, tube-like darts, if it hits the beast, it contains the beast in the dart, shrinking it and freezing it to stop their rampage. /it is Futuristic, with buildings and stuff looking the same as they do now, but with slight differences with extra tech in buildings and that/ The gods also did one more thing before going into their disappearance. All humans that did not have abilities forgot about the Magic in the world.
