Human

Humans (人間) are one of the four main races, alongside demons, spirits, and gods.

Overview
Compared to the other races, humans live relatively short lives. Whereas spirits and gods can live almost indefinitely, and demons can live for thousands of years, no known human has ever lived for more than a hundred years. The magic power of humans is also on the weak side, causing them to rely on wits and cunning instead. This in turn led to human society having a lot more scammers and fraud in general than the other races. It's also the reason why they are able to come up with far more insidious and nasty schemes than demons.

Powers and Abilities
Despite being weaker than demons in terms of magic power, humans are suited to using holy magic which is particularly effective against demons, because it can seal their power and severely weaken them. The main spell that gave humans an advantage against demons is Aske, which allows humans to convert their feelings into magic power and strengthen their bodies. This was the only way that the weaker humans could stand a chance against demons, who possessed greater magic power. Some exceptional individuals are chosen by holy swords, becoming a hero (勇者) in the process. These holy swords are magic items superior to demons swords with the ability to seal the magic of demons. These swords can also be used to enhance the power of holy magic. In addition, humans can also use the power of holy water to further strengthen themselves, as it gives them more magic power while also being toxic to demons.
