《Gem》 ??? (Titanium Alloy) Hardness: ??? 《Details》 Our Supreme Leader, the origin and the pinnacle. Stronger in the heat, but prefers and excels in winter (HoI2). During hibernation, he's prone to breaking or being broken, so he crafted his own protective capsule. (Wrwrd TRPG: Unique Equations)

《Gem》 Ruby. Hardness: 9 《Details》 Head of the patrol team and effectively the second-in-command. If Gruppen can't make it in time, people go to him. Because their hardness and toughness are similar, he partners with Zomu, but he often gets hit by stray shots; since his outfits use a lot of fabric, the clothing designer cries. He once suggested wearing the same clothes as everyone else, but the designer said, "It just doesn't feel right." Quick to sense danger and skilled at knowing when to retreat or evade, his main job is collecting the frequently rampaging Zomu at the right moment. (Wrwrd TRPG: That Man, Food Damage)

《Gem》 Green Diamond. Hardness: 10 《Details》 Patrol duty. The strongest combatant, but a major threat because he touches others without considering his own hardness. Because he recovers every single gem embedded in the new Lunarian models, he was dubbed the "Zomunter" instead of just a hunter. He seems to really like his current shoes.

《Gem》 Iolite. Hardness: 7-7.5 《Details》 Clothing designer. He is the one who suffers most from Zomu and Tonton's fighting styles. However, due to his own professional pride, he repairs them faithfully every time. In the past, he committed the eccentric act of using hemp intended for hibernation clothes to make a giant stuffed animal and got scolded severely. (Wrwrd TRPG: Utsu, Be Sharp)

《Gem》 Star Lemon Quartz. Hardness: 7 《Details》 Patrol duty and messenger, thanks to his loud, clear voice. Shoppi is his second partner. Unlike Emil, who wears winter clothes year-round, he wears summer clothes year-round. His current worry is that he can't seem to find what he's looking for.

《Gem》 Andalusite. Hardness: 6.3-7.5 Weapon production. He used to have longer hair, but it was cut short during an internal conflict back in the day. He joined at the same time as Koneshima. He shows no mercy to friend or foe alike. Lacks agility, but his single strikes are devastating. A hard worker.

《Gem》 Rhodochrosite. Hardness: 4 《Details》 Chairman and the group's mediator (The Voice from the Heavens). Rarely gets angry, but when he does, it's terrifying; the cause is usually Zomu, Utsu, or Koneshima. He was granted permission to replace both arms with Yellow Sapphire, if only for the grip strength. He occasionally goes to the front lines as backup, but he is frequently irritated by Zomu's reckless fighting style.

《Gem》 Sinhalite. Hardness: 6.5 《Details》 Scribe. He transferred from patrol duty to his current position. He is highly knowledgeable because he has pored over every possible record. Strong in intellectual matters, he boasts a high accuracy rate for predicting Lunarian appearances (from Lateral Thinking). For some reason, he stubbornly refuses spring and summer clothes and wears winter clothes all year, earning him the nickname "Springless."

《Gem》 Purple Zoisite. Hardness: 6-7 《Details》 Usually expressionless and listless, but gets his work done perfectly. Though not his specialty, he is good at medicine and focuses on repairing the younger gems. He is the last one to wake up from hibernation.

《Gem》 Green Turquoise (Emerald). Hardness: 5-6 《Details》 Strategy and command. He tends to get reckless when things get stuck. For the last few hundred years, he has dumped everything on Emil to focus on research. Clothing designer's "It just doesn't feel right" #2. Younger than Gruppen, older than Tonton.
