Hardness: 3.5 Toughness: Lowest class Role: Natural History Encyclopedia -> Winter Duty Nickname: Phos Once a pure Phosphophyllite, but after losing arms and legs, the legs were replaced with Agate and the arms with Gold-Platinum Alloy. Unlike before, Phos has become strangely calm. The former bright personality is rarely seen. This change occurred after Antarcticite, who briefly shared winter duty, was taken to the Moon. Phos occasionally sees hallucinations of Antarc. Mentally unstable. When triggered (related to Antarc), Phos attempts self-harm, such as shattering their own head with the alloy. When fighting Lunarians, Phos is obsessed with checking if they are old or new models to find Antarc's fragments. Phos controls the alloy freely, using it like tentacles. The heels of their shoes are made of alloy, and they can stretch the alloy to use as platforms to reach high places. Various shapes can be formed, though there seems to be a limit to how far it can stretch. Phos became smarter after losing Antarc. Not necessarily a genius, but unlike the previous airhead self, they have become strategic and serious. Phos has begun to doubt Sensei's true identity. Memory loss occurred along with the loss of limbs.

Hardness: 3 Toughness: Grade 4 Role: Winter Duty Nickname: Antarc Shared winter duty with the innocent Phos but was shattered and taken by Lunarians after an attack. Only the left foot remains. Stays in a liquid state in a tub before winter, but turns solid and active like other gems when winter arrives. When attacked by Lunarians, Antarc crumbled after telling Phos to take care of the winter. Even while shattering, Antarc made a 'shush' gesture to hide Phos from the Lunarians out of concern. Calm, wise, and strict. However, Antarc was perhaps the only one who treated Phos as a true friend. Occasionally appears to Phos, says a few words, and then shatters and disappears. This is merely a hallucination caused by Phos's trauma; the real Antarc is on the Moon.
