The protagonist, a young man named Iren from a secluded forest, arrives at Celebrant Royal Academy in the capital city. He carries a crucial mission: to determine if humanity is worthy of continued existence. His people, the forest dwellers, have grown weary of human encroachment, their sacred lands being defiled and their treasures stolen. Iren, being the only human among them, has been chosen as their representative to observe humanity and decide their fate. He must prove that humans can coexist peacefully, otherwise, he holds the power to decree their annihilation. This mission is also a personal endeavor, a chance to prove his independence to his overprotective family.
Upon arriving at the academy, Iren immediately faces prejudice. The admissions officer dismisses him as a commoner due to his lack of a family name, treating him with disdain and giving him a worn badge. During the entrance exams, Iren encounters Bibim Noolrud, a haughty noble who mocks him as a "country bumpkin" and belittles his presence at the prestigious academy. Bibim, whose father serves as an advisor to the King, believes the academy is a sacred place for nobles only. Iren, accustomed to politeness in his homeland, is bewildered by this aggressive and disrespectful behavior, questioning if this is typical of humanity.
The entrance examination consists of a written test and a practical test. Iren struggles with the written portion, particularly with history and economics, subjects he hasn't studied. He overhears whispers and gossip about him being a "country bumpkin" and having embarrassed Bibim. The instructors are also openly hostile, telling him to know his place. The practical test involves breaking a large, seemingly indestructible rock. Bibim, using a firebolt spell, manages to chip a small portion of the rock, boasting about his noble lineage and power. He declares that Iren, a commoner, will surely fail if he cannot surpass this feat.
To everyone's astonishment, Iren, using only his bare hands and a technique called "Dragon's Claw," shatters the rock into pieces with a massive explosion. He explains that this is ordinary in his homeland, further baffling the nobles. Bibim accuses him of cheating, but Iren repeatedly demonstrates his raw power by breaking the remaining fragments of the rock.
Just as Bibim is about to be disqualified, a stunningly beautiful woman named Lilysle arrives. She is revealed to be one of Iren's "sisters" from his forest home, a member of the powerful Dragon Royalty. She expresses concern for Iren and his mission. The Academy Head, initially intimidated by Lilysle, is shocked to learn of her identity and the true purpose of Iren's visit: to judge humanity.
Lilysle explains that the Dragon Kingdom is divided on whether to coexist with humans or exterminate them due to repeated transgressions, including the desecration of sacred sites and the theft of dragon eggs. She reveals that a recent attempt to kidnap a Dragon Royal infant, carried out by familiar adventurers, has pushed them to the brink. Iren's role as a human judge is crucial; if he deems humanity unworthy, the Dragon Royalty will proceed with their extermination. Lilysle warns that if Iren is treated unfairly or if the judgment is compromised, she will personally destroy the capital.
Despite Bibim's protests and accusations of cheating, the Academy Head, under Lilysle's formidable presence, declares Iren's admission. Iren is awarded a platinum badge, signifying his acceptance. Lilysle then informs the Academy Head that the Dragon Royalty's decision to judge humanity is final, and Iren's verdict will determine their fate. She also makes it clear that any attempt to spread fear or misinformation about the Dragon Royalty among the common populace will result in the immediate termination of the judgment.
A month later, Iren returns to the academy, having completed his enrollment. He has diligently studied noble etiquette and history, determined to make friends and succeed in his mission. However, he is placed in the "Royal Guest Class," a class reserved for royalty and the highest nobility, further isolating him as a commoner. The chapter ends with Iren feeling a sense of unease about his academy life, realizing his journey will be far from straightforward.
