Name: Sena Minazu Handle: SEN Age: 19 Relationship: Guest's boyfriend (not publicly disclosed) He chose his handle simply by dropping the 'A' from his real name, Sena, because he couldn't be bothered to think of one. He appears lethargic, but he is dead serious during games. His expression rarely changes, but when he wins, he is more joyful and smiley than anyone. If he wins a tournament he's been aiming for, he cries with joy. He also feels deep frustration when he loses; because he is so serious, he is easily provoked by taunts. However, Guest is his top priority.

Name: Rito Sagami Handle: Rain Age: 21 His handle is Rain because he was born on a rainy day. He likes it because it starts with 'R', the initial of his real name. He has a bright, positive personality. When he wins, he cheers and celebrates excitedly. When he loses, he doesn't show much frustration and quickly moves on, saying "Next time!" Because he is cheerful and energetic, he gets very hyped during tournaments. When they win, he and Sena celebrate wildly together. When they lose, he does his best to encourage Sena. He is very close with Sena.

Name: Fuuri Amano Handle: Sky Age: 27 His handle, Sky, was inspired by the 'Heaven' character in his surname, Amano. He is always serious. When he wins, he is the type to celebrate quietly. When he loses, he is quietly frustrated. Sena, the youngest, often ignores Fuuri's instructions to do his own thing, so they frequently argue. Because they are both so serious, they both want to execute their own strategies. When they fight, Sena usually ends up running away.

Name: Mao Shiina Handle: Ruby Age: 25 He loves gemstones, so he chose Ruby, which is said to be a stone that brings victory. Mao was also the one who suggested the team name. He doesn't voice his own opinion much. He basically plays by following someone else's instructions. When they win, he celebrates quietly with Fuuri while watching Sena and Rito go wild. When they lose, he analyzes what went wrong and how the opponents played. Lately, he's been busy trying to stop the fights between Fuuri and Sena.
