Male. His signature color is Red. He is the leader of the Quail Five. True to his Red status, he is hot-tempered and frequently nags the other members. He can be inflexible, tends to cut corners on tasks, and often acts undignified for a leader. However, he does show leadership qualities, such as taking commemorative photos with citizens even when he's supposed to be heading to watch the World Cup, or sternly reminding Whimbrel of the Doctor's instructions during Christmas while the others were just enjoying the holiday mood. That said, he has a bit of an old-school 'boomer' mindset, scolding others for not focusing on hero work even when it's a holiday.

Male. His signature color is Blue. His only recorded 'misdeed' so far was ringing the emergency summons bell because he lost his card wallet. Compared to Bulbul, who blew team funds on in-game microtransactions, Blue Crane showed a sense of responsibility similar to Quail by paying 170,000 won of his 260,000 won shoulder dislocation treatment out of his own pocket. He is currently the only martial artist among the Quail Five and the only one capable of using superpowers for practical combat. He is a high-ranking Taekwondo black belt and possesses psychometry powers.

Male. His signature color is Green. He has a heavy build, wears glasses, and has curly hair. He is a character designed to embody the negative tropes of the 'fat character' archetype—gluttony, otaku tendencies, stupidity, and intermittent explosive disorder. Perhaps because of his unlikable traits, he has a high proportion of lines.

Female. Her signature color is Pink. She is the only female member of the Quail Five. Surprisingly, she has a short haircut. She is usually glued to her phone and obsessed with social media, but she has the strongest survival skills and life management among the members. She first appears having her yogurt and 50,000 won stolen by Bulbul and Whimbrel respectively. In the 'Disbandment' arc, she shows her sharp side by suggesting to the Doctor, who is considering disbanding due to lack of funds, that they should 'recruit more members and operate in shifts to save money.'

Birthday is April 1st. Male. His signature color is Yellow. He is quite serious. For some reason, he is often ignored or picked on by other team members (especially Quail) even when he hasn't done anything wrong. Other traits include being a 'mansplainer' or being socially dense. He is said to be lactose intolerant.

The scientist for the Quail Five, acting as their founder and supporter. He is responsible for sounding the siren to alert the team when there is a mission. He is male and quite elderly.
