Human

Humans, also known by Gods as Mortals, are inhabitants from both Earth and Tortus.

Earth Humans
They are the only sentient race that inhabit the planet of Earth. Unlike other humans from other worlds, they do not possess any unique abilities.

Mana Blessed
The human race of Tortus is one of the most populous if not the most populous race on that inhabits Tortus. Unlike the humans of "Earth" or the "World of Sky", the humans of Tortus possess the ability to use magic due to possessing mana which allows them to cast spells with various effects. Unlike Demons or Vampires, Humans have a relative moderate understanding of magic.

There is a group of Earth Humans who were summoned by the gods and were blessed with Mana and forming the so-called "Hero Party". They are considered the strongest humans on the face of Tortus and Earth.

Human/Monsters Hybrids
Human/Monster hybrids are rare species of humans who gained monstrous appearance and inhuman strength through mutations from consuming monsters' meat and drinking liquefied mana. Their original bodies changed into muscular and taller body. Their strength, speed, senses are stronger then beastmen and ordinary monsters and their mana is even more powerful than normal mana blessed humans, and demons as their strength and abilties are completely inhuman and monstrous. Due to withstanding the fatal ingestion of monster flesh, they can further increase their stats and gain the special magic/skills of the monsters that they absorb. They have purple spiked bloods cells, red tattooed-like veins even both their hair turned from original to white and eyes turned to crimson red. Their mana turned from normal to crimson. They are not in fact, humans anymore. According to Cattleya, if the hybrids are anything like the ordinary monsters, both of their monstrous and inhuman strength were checked out. Only Restoration magic can recover a Human/Monster hybrid's full condition.

Zombies
Zombies also known as the Undead, are deceased humans who are reanimated from the dead. For normal zombies, They are eater that eats living organisms. They don't have their human memories. They are infection and disease when bite or scratch turn them into zombies.

In Tortus, zombies who are reanimated by Eri Nakamura are not eaters but rather soldiers who are controlled by Eri as puppets. They're not in fact, an infection or a disease. Their souls were tormented and enslaved by Eri to do her bidding. The only why to free the souls of the dead is to destroy the body or head.
