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

《Gem》 Ruby. Hardness 9 《Details》 Head of the patrol and effectively No. 2. If Gruppen can't make it in time, people go to him. He's paired with Zomu due to similar hardness and toughness, but he often gets hit by stray shards; because his clothes cover so much surface area, the tailor cries. He once suggested wearing the same clothes as everyone else, but the tailor said, "It's just not right." Quick to sense danger and skilled at knowing when to retreat or evade. His main job is retrieving the habitually reckless Zomu at the right moment. (Wrwrd TRPG: That Man, Food Harassment)

《Gem》 Green Diamond. Hardness 10 《Details》 Patrol member. The strongest combatant, but a major threat because he touches others without considering his own hardness. He retrieves every single gem embedded in the new Lunarian models, earning him the nickname "Zomuter" (The Hunter). He seems to really like his current shoes.

《Gem》 Iolite. Hardness 7-7.5 《Details》 Tailor. The one who suffers most from Zomu and Tonton's fighting styles. However, due to his own professional pride, he repairs their clothes faithfully every time. He once went on a bizarre streak of using hemp meant for hibernation clothes to make a giant stuffed animal and got scolded severely. (Wrwrd TRPG: Utu, Be Sharp)

《Gem》 Star Lemon Quartz. Hardness 7 《Details》 Serves as both a patrol member and a messenger due to his loud, clear voice. Shoppi is his second partner. Unlike Emil, who wears winter clothes year-round, he stays in summer clothes year-round. His current worry is that he can't seem to find things he's looking for.

《Gem》 Andalusite. Hardness 6.3-7.5 Weapons Smith. He used to have longer hair, but it was hacked off during an old internal conflict. He joined at the same time as Koneshima. Relentless toward both friend and foe. Lacks agility, but his single strikes are devastating. A hard worker.

《Gem》 Rhodochrosite. Hardness 4 《Details》 Chairman and the group's coordinator (The Voice from the Heavens). Rarely gets angry, but when he does, it's terrifying. The causes are usually Zomu, Utu, or Koneshima. He was granted permission to replace both arms with Yellow Sapphire, if only to improve his 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. Switched from being a patrol member to his current role. He is highly knowledgeable from reading through all sorts of records. Strong in intellectual matters, he boasts a high accuracy rate in predicting Lunarian appearances. (From Lateral Thinking) For some reason, he stubbornly refuses spring and summer clothes, wearing winter gear all year, which earned him the nickname "Springless."

《Gem》 Purple Zoisite. Hardness 6-7 《Details》 Usually expressionless and lethargic, but performs his duties perfectly. While not his specialty, he is skilled in medicine and often 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 becomes dismissive when things get bogged down. For the past few centuries, he has dumped all his work on Emil to focus on research. The tailor's "It's just not right" ②. Younger than Gruppen, older than Tonton.
