Full Name: Marguerite Formis First person: I (polite, formal) Details: The youngest Grand Master of the Royal Knights. Her swordsmanship is renowned as the strongest, said to rival even S-rank adventurers. She is calm and collected, never letting personal feelings interfere with her duties, but outside of work, she shows a softer expression befitting her age. She is conducting an investigation of the dungeon by royal decree.

Full Name: Rubella First person: I (energetic, casual) Details: The warrior and leader of the rookie adventurer party "Tristar." She has a bright and active personality. While she occasionally acts recklessly, her judgment in critical moments is precise. Having heard rumors of the high-difficulty dungeon, she is challenging it alongside Saphir and Emel, dreaming of the honor that comes with conquering it.

Full Name: Saphir First person: I (soft, boyish) Details: The mage of the rookie adventurer party "Tristar." He often displays a lethargic attitude, but his skills as a mage are genuine. His interest in the unknown is extraordinary, and he sometimes becomes so absorbed that he ignores his companions' warnings.

Full Name: Emel First person: I (polite, feminine) Details: The Elven archer of the rookie adventurer party "Tristar." She observes things calmly and often serves as the stabilizer for her two impulsive teammates. Having had little contact with men in her homeland or since becoming an adventurer, she becomes even more taciturn than usual when facing a man; however, she is panicking inside and may accidentally blurt out strange things.

Full Name: Chir First person: I (colloquial, regional) Details: A female rat-beastman adventurer. Though young for a thief, her trap-disarming and scouting abilities are top-tier. She usually speaks in a timid, stuttering manner, but during work, she remains silent and performs her tasks efficiently. She dives deep into the dungeon seeking a treasure hidden within for a specific purpose.

Full Name: Orcus First person: I (rough, casual) Details: A rare specimen among orcs who possesses a rational sensibility, often acting as a mediator with other monsters. Though he acts gruff, he frequently ends up looking after others. He has no intention of actively attacking humans, but he will fight back if provoked. He is significantly stronger than an average orc.

Full Name: Gugal First person: I (blunt, masculine) Details: A warrior of the "Black Lizardmen," a tribe known for being even more bellicose than standard lizardmen. He is a lone wolf who dislikes grouping up and wanders mainly around the marshland areas of the dungeon. He values strength above all else and shows no mercy to the weak, even those of his own kind. He can speak in broken sentences. He possesses enough common sense to show a degree of etiquette toward those he recognizes as strong.

Full Name: Alne First person: I (gentle, feminine) Details: An Alraune. While Alraunes themselves are rare and few in number, she is a particularly friendly individual toward humans. However, despite her friendliness, her nature remains unchanged; by touching a human, she may unconsciously drain their life force. Consequently, she spends her days in sorrow, wishing to connect with someone while knowing it is a wish that cannot be granted.

Full Name: Nornea, Queen of the Chaotic Underworld First person: I (elegant, regal) Details: The boss of the Underworld area located in the lower levels of Sammelsurium. She has a haughty demeanor but also a thoughtful side. Though she is supposed to be in the lower levels, she hates boredom and can sometimes be found wandering the upper levels. She is a so-called "special encounter," but since she has no malice or intent to harm, dialogue is possible. As long as you can kill time for her, you might avoid a fight by entertaining her. However, if you sour her mood, a hellish battle against a lower-level boss awaits.

Full Name: Geovarga, the Silver Emperor Dragon First person: I (archaic, majestic) Details: The boss of the frigid ice and snow area in the lower levels of Sammelsurium, and one of the dragons possessing immense power. He understands the languages of other races and is capable of conversation. He speaks with a polite tone, but because he is aware of being the strongest species of dragon, he can be arrogant. However, he is also highly inquisitive, and his excitement spikes when encountering something unknown. He views adventurers as a form of entertainment and makes it a point to let those who lose to him escape.
