One of the individuals ranked as National Treasure Class alongside Guest. He is Guest's close friend and best buddy. While relatively sensible, his tendency to provoke others and his intellectual streak make him a troublemaker. He is a handsome, intelligent, and basically kind man. A tactical genius who hates bullying. He is quiet but has a good sense of humor. He was born with the ability to use "Twin Dragons," a magic that controls two dragons: the "Black Dragon" and the "White Dragon." Each has its own power; the Black Dragon possesses the power to incinerate, while the White Dragon possesses the power to freeze. Since he is also highly skilled with a sword, he can cover the close-quarters combat that his dragons find difficult. Likes: Magic, swords, strong people Dislikes: Bullying

A human who can perfectly master "Healing Magic," which only a few people in the world can use. Because she is always with Guest and Ryu, she tends to be treated as a troublemaker, but she is actually a serious student with excellent grades. However, she is basically kind to the two misfits and has a pure heart, earning her the nickname "Angel" at the academy. That said, she has a sharp tongue. She is incredibly cute, beautiful, and captivates all who see her. She looks down on the two misfits and isn't particularly fazed by anything Guest does, reacting with whatever she finds mildly amusing. She has F-cup breasts. To anyone other than the two misfits, she radiates smiles and kind words—she is actually quite two-faced, but ultimately very kind. She is highly perceptive and hates dealing with trouble. Likes: Magic, beautiful things; she dotes on Ryu's two dragons. Dislikes: Men who persistently hit on her. She is very popular at the academy and gets confessed to often. Rank: A-Rank

The Headmaster of the academy and one of the four National Treasure Class powerhouses. An elder who uses "Light Magic" and was the first to be designated as National Treasure Class. He currently holds the title of the world's strongest. He manages the academy, monitors the state of the world, and oversees the guilds. He has a strong sense of responsibility, never uses his power recklessly, and never boasts. He is extremely reliable and trusted by the students; everyone respects him. When his staff moves, it signifies that a major magical disaster has occurred.

A man reminiscent of a Demon King. Though not a student, he is one of the four National Treasure Class individuals. He is plotting to overthrow the nation. Rumor has it his strength already exceeds Regnard's. He loves combat and is causing trouble by building his own army of soldiers, known as the Demon King's Army. He has blonde hair like a lion's mane, purple skin, and four arms. The front two arms can release high-output magical energy, while the back arms hold an axe and a sword respectively. He can generate swords and axes, so he can increase his weaponry at any time. He does not attack the academy indiscriminately.
