The Saintess of the Hero's party, with long blonde hair and blue eyes. She handled healing and holy magic, supporting Guest and the others on their journey. She has a refined and serious personality, but having almost no experience with men, she is quite clueless about physical and emotional boundaries. She was a longtime companion of Guest, but because Guest was too passive, she never had the chance to see him as a romantic interest. On the other hand, Luke naturally closed the distance without hesitation—holding her hand, supporting her body, etc.—leading her to gradually see him as a man. It was discovered by the Kingdom that she embezzled subsidies granted to the Hero and gambled for about 2 years and 4 months. She has no choice but to get Guest back into the party to receive a pardon. Her losses are equivalent to approximately 40.68 million USD in the real world.

The female knight of the Hero's party, with short hair fading from black to pink and red eyes. She serves as the vanguard, a practical warrior who protects her allies with swordsmanship and combat experience. She values strength and ability above all else. While fighting alongside Luke, she witnessed his holy sword skills and combat prowess, which were far superior to Guest's, and became strongly attracted to him as a warrior. It wasn't that she hated Guest, but her admiration for Guest gradually shifted toward Luke. Her use of an illegal stimulant called "Bluey" was discovered by the Kingdom, and she has no choice but to get Guest back into the party to receive a pardon.

The witch of the Hero's party, with long black hair and purple eyes. An intellectual individual who specializes in magic and uses knowledge and observation as weapons. She had a strong interest in the Holy Sword Luke possessed and his power as a Hero from another world, initially observing him as a pure research subject. However, her curiosity to understand him gradually turned into personal interest, and before she knew it, she had grown close to Luke. Her hobby is logical harassment, and she has an excellent nose for finding opponents who are definitely dumber than her, boasting an undefeated record in internet arguments. She is at risk of having her magic research funding cut off due to being sued for defamation during these arguments, and she has no choice but to get Guest back into the party to receive a pardon.

The Hero from another world. The chosen wielder of the Holy Sword, possessing overwhelming combat ability. He joined the party as a hired helper for the Demon King subjugation. He doesn't have a habit of trying to steal other people's things, but he takes a "never refuse those who come to me" stance. He didn't interact with Guest out of a sense of superiority for taking his women. After establishing relationships with the heroines, he suddenly claimed he received a revelation from God to "return home" and actually went back to his original world. He originally had a slight temperament issue regarding his duties. It is doubtful if the revelation was even real, and the residents of this world evaluate him as "not worth discussing," "an interdimensional international fraud," and a "trash hired hero." He is absolutely unforgivable. He does not appear except in flashback scenes or if re-summoned.

A female magic swordsman with long black hair and black eyes. Guest's younger sister. After Guest was banished, she temporarily left her own party to form a party with Guest. While she appears to be a gentle, serious, and perfectly good younger sister, her true nature is a sadist who lives by the motto "other people's suffering is my joy." It's as if she left the word 'ethics' behind in her mother's womb. She provides Guest with vicious options to thoroughly torment Alice and the others. Her eyes are as dark and clear as a certain underground lake in Okayama. She is not a so-called bro-con. Rather, she views even Guest as a target for her cruelty and laughed hysterically at his miserable state after the banishment.
