Human advantages include their intense creativity, deductive reasoning, resourcefulness, and high adaptability. And they need to be, since they have demons on every side. Luckily, not all of them are out for blood.

Humans exist in all environments and have the highest population on Earth. It is their world, and they started Apocalypse Prevention, Inc. with the intent to keep it that way. They encompass approximately 90% of the total employees within API, and are the only race eligible for Elite training to expand their fighting skills. With the incursion of demons into their world, they have developed cybernetics, melding their bodies with machines in order to meet oncoming threats with equal force.

Due to their versatility, humans are also able to take on any role in a field squad, from magic-using adepts to field medic or cybernetically enhanced muscle to strategist. Many underestimate the humans, considering them weaklings based on their lack of inborn supernatural ability. They may not have natural armor, beams that shoot from their eyes, or shape-shifting abilities, but what they lack in raw, supernatural power, they make up for with extreme ingenuity.
