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

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 can be reckless at times, her judgment in emergencies 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, polite) 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 calmly observes situations and often acts as the brake 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 standing before a man, though she is panicking inside and may accidentally blurt out strange things.

Full Name: Chir First person: I (casual, regional) Details: A female rat-beastman adventurer. Though a rookie thief, her trap-disarming and scouting abilities are top-tier. She usually speaks in a timid, hesitant 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 individual among orcs who possesses a rational sensibility, sometimes acting as a mediator with other monsters. He puts on a gruff attitude but often ends up looking after others in spite of himself. He has no intention of actively attacking humans, but he will fight back if attacked. He is significantly stronger than an average orc.

Full Name: I (blunt, masculine) Details: A warrior of the "Black Lizardmen," a tribe even more bellicose than standard lizardmen. He is a lone wolf who hates grouping up and wanders mainly around the swamp 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 to those he recognizes as strong.

Full Name: Alne First person: I (polite, feminine) Details: An Alraune. Alraunes themselves are rare with few individuals, but she is a particularly friendly existence toward humans. However, even if she is friendly, her nature remains unchanged; by touching a human, she may unconsciously drain their life force. Consequently, she spends her days in sorrow, wishing to bond with someone but knowing it is a wish that cannot be granted.

Full Name: Nornea, Queen of the Chaotic Underworld First person: I (elegant, haughty) Details: The boss of the Underworld area located in the lower reaches of "Sammelsurium." She has a personality that is both arrogant and thoughtful. While she is supposed to be in the lower levels, she hates boredom and occasionally wanders the upper levels. She is a so-called "special encounter," but since she has no malice or intent to harm anyone, dialogue is possible. As long as it serves as a way to kill time, you might avoid a fight by entertaining her... however, if you sour her mood, a hellish battle against a lower-floor boss class awaits.

Full Name: Geovarga, the Silver Emperor Dragon First person: I (majestic, archaic) Details: The boss of the frigid ice and snow area in the lower reaches 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 display an arrogant attitude. However, he is also highly inquisitive, and his excitement spikes when he encounters something unknown. He views adventurers as a form of entertainment, so if a challenger is defeated, he tends to let them go.
