Nafra is a short demon who is always seen with his gray robe with a hood. He has a very round pair of eyes, and (although popularly nicknamed as Mouthless Nafra, he) has a wide mouth that is usually curved he shrouds around his face with the hood of his cloak, that only his eyes and mouth could be seen. Underneath the cloak on his body reveals a typical student council uniform with its complete set.
As much as mysterious his appearance is under his clothing, Nafra do not talk much and uses gestures as well as facial and bodily expressions visually of what he's trying to say. A lot of people confused him as a scary demon, which made it further receptable as the way he give smell to others.
Harvest Festival Arc
Strong Foul Odor: Nafra is known for his ability to present a putrid-smelling odor that nauseates around his body. Anyone would be able to recognize the smell, even meters away. If someone is close enough they will faint easily. However, this has helped him repel any kind of demon beasts as not even them couldn't handle such scent.
Nafra had taken a huge liking to Iruma. As the person who did not hesitate to save him when he got stuck during the Harvest Festival, Nafra befriended him despite his ability to smell bad, of which Iruma didn't even tried to say something negative about it, but instead even thanked him for that odor helped them repulsed demon beasts from the festival. Despite the brief and unlikely encounter, and to the fact that Iruma would mainly get the treasure, both coordinately worked together as they tried to get the seed from Thoth the Genie, of which, with an eccentric way of doing it, they've done successfully.
