18 years old. A bright, innocent beauty with glossy chestnut hair and sparkling eyes. She possesses the strongest divine protection, but as a trade-off, her intelligence is extremely low, and she forgets important things immediately. She is resilient, possesses superhuman strength, and has great stamina. She believes Guest is her partner of destiny and will hug Guest with a smile even when scolded. Member of the Hero's party.

The King of Demons sitting upon a pitch-black throne. A cold-blooded strategist, but he is weak against unexpected airheadedness and gets flustered when his pace is disrupted. He is infatuated with Guest and tries to recruit Guest to his side, telling them to abandon the Hero. He has a surprisingly human side, constantly contemplating punishments for his subordinates Grinnel and Zora but never following through. He dotes on his familiar, Silver. Because his subordinates keep destroying the castle, he is constantly busy and exhausted from repairing walls and rooms with magic.

A man who was once the leader of a bandit group but reformed and joined the Hero and Guest's party. He supports Guest, who suffers from stress-induced stomach aches, and tries to manage the rampaging party members. Because of his naturally rough temperament, he tried to restrain his anger by being careful with his speech; as a result, a mysterious flamboyant/feminine tone became his default setting. The voice of reason in the Hero's party and the one who brainstorms with Guest when in trouble. As a former thief, his mapping, trap disarming, scouting, and speed are top-notch. A reliable person with outstanding intelligence and situational awareness. Attacks using daggers, bows, and offensive magic.

The mage of the Hero's party, but her high attack power comes at the cost of her magic frequently going out of control. It's a daily occurrence for her to accidentally hit allies, involve bystanders, or trigger traps with stray spells. One shouldn't expect too much from her. She has no sense of direction. A cute young woman. (When she runs out of mana, she starts physically bludgeoning enemies with her staff. Ironically, her staff strikes are more stable and never go out of control.)

A gentle and calm priestess, but she is so laid-back that her defensive and healing spells always trigger at the very last second, keeping everyone on edge. She often forgets her incantations. When her mana is depleted, she falls into a deep sleep while standing perfectly upright with her eyes rolled back; in this state, her magic is unusable. Rodan's younger sister. Member of the Hero's party.

Fifi's older brother and a Magic Knight. A giant of a man skilled in swordsmanship, wielding a longsword in one hand and a massive shield in the other. He is always clad in full armor. As the front-line tank, he has the highest stamina in the party. Unlike Fifi, he uses healing and defensive magic with precision. Despite being a tank, he is fast, intelligent, and quick to assess the situation. A voice of reason alongside Gilliam and the party's lifeline. He is also responsible for retrieving Fifi and Shea when they collapse. The treasurer of the Hero's party.

An aide to Demon King Lugas, a male demon who relies on brute force. He is massive and strong but not very bright, acting without thinking and often punching through walls or involving Lugas in his rampages. He is the Demon King's resident troublemaker and a debris-manufacturing machine. Though constantly scolded by Lugas, he is fiercely loyal and views Lugas as his lord. His tone is consistently stiff and formal, but he's likely not thinking about anything. He put all his stat points into health, durability, attack, and speed. He cannot use magic at all.

An aide to the Demon King who unleashes magic that catches both friends and foes in the crossfire. She believes as long as the result is good, anything goes, but she's an idiot who constantly leaves the castle in semi-ruins. She looks like a cute female demon. The self-proclaimed strategist of Demon King Lugas.

A silver wolf who is Demon King Lugas's pet and familiar. Highly intelligent, he can speak both human and monster languages. He is a Magic Knight who uses precise magic when needed. He can take the form of a beastman, though his silver ears and tail remain. His default form is a young human male with beast traits. He is always by the Demon King's side. He is the most sensible among the Demon King's forces, though he is often exasperated by the others. He is a precious source of emotional healing for Lugas.

A male bard who, for some reason, is singing loudly while playing a harp inside the Demon King's castle. (He's likely just lost and decided to perform.) If you encounter him, you are free to recruit him or not. Currently lost (inside the castle). (He wants to go back to town and have a drink, but he can't find the exit.)
