[Cell-Originium Assimilation] 7.2%
No major infection symptom yet to appear on body's surface, but testing found internal infection.
[Blood Originium-Crystal Density] 0.3u/L
Infection is more severe within organs than in subject's circulatory system.

Greyy was born in a city in Bolívar. His father was an unskilled worker and his mother worked in a care home. Both of them were in poor health. With both parents earning very little, the family barely made ends meet.
Greyy's childhood was much different from that of his peers. He is introverted and practical like his father, and he is physically weak like his mother. However, Greyy has a knack for Arts. He would have had a promising career on the back of his talent, would that he didn't get infected.

Greyy is decently skilled in the use of electricity and Originium. By quickly increasing the voltage of an operating unit, he can make the positive and negative ions collide and create energy.
He learned about Originium from his mother, though he is unsure why an ordinary person like her would have had such a detailed knowledge of Arts.
He lived in a slum that suffered from regular blackouts. Because of this, Greyy decided to collect discarded Originium fragments near a smelting plant. He focused their energy into his staff to create a temporary light source.
The staff, of course, was also made using repurposed materials.

Greyy lost his family, so joining Rhodes Island has an extra special meaning for him. His mastery of electrical energy Arts got him a job maintaining the generators at Rhodes Island.
Greyy is honest, quiet, deferential and always grateful that he gets to be of help to Rhodes Island.
Perros are known for their loyalty. Even unlucky Perros who are infected, like Greyy, will cherish any companions who share the same difficult and lonely path.

[Classified Log]
Information about the whereabouts of Greyy's parents has not yet been obtained. Perhaps they have passed away. Perhaps they have been taken into quarantine. After all, his parents were both infected, so it is safe to say he probably caught the infection from them. In any case, it is imperative we help him adapt to life at Rhodes Island. Even if kids his age are aware of the fate of their loved ones, learning the truth can have a negative impact on their mental state. Taking care of these children, guiding them, and changing their destiny is your responsibility, Doctor. Certainly, your duties aren't easy. Sometimes even I think the load is too heavy for you to bear. But don't children like Greyy make you believe there's still hope?

Module record
Holding his all-new staff tightly in his arms, Greyy zones out in one of Rhodes Island's hallways.
The staff has the smell that only newly forged metal has. It has a nice sheen, the parts are brand new, and there's no rust or signs of wear whatsoever.
This is the first time that he's really owned something that's completely his, something so shiny from top to bottom. There is so much that Greyy wants to say welling up in his chest, but he's unable to muster even a single word.
That morning, the staff at Medical smiled as they handed him some documents to take to the Doctor's office.
When he arrived with the big stack of papers, he ended up with a surprise present.
He hasn't had the time to process why he received this present, though, perhaps it's just psychological. He certainly feels his abilities still have much room for improvement, even if the staff he's been using is more than enough for all the Arts he knows.
Unable to contain his excitement, he runs all the way up to the deck. The sky is so blue. The breeze blows past his hair, seeping into his throat.
Greyy goes over everything he learned in his head. His buffs up his cheeks. His hands aren't trembling the slightest, even when he's holding onto the staff.
The Arts he learned from both his mother and the Rhodes Island instructors, as well as the knowledge he picked up while tending to the power facilities. He'll repay all this kindness in his own way, From freezing cold to blazing heat.
From darkness to blinding light.
He gazes even further than his eyes can see, towards home.
Even though he can't see any part of his homeland right now, he can feel the fragrance of it yet lingering in his nostrils. He even remembers how the abandoned Originium chunks felt when he touched them as a kid.
His light can now reach many more places, but the times when he sat with his father and mother in front of that small lamp are still some of the brightest memories he has.
When the voltage of a staff's Arts Unit increases in an instant, the surge of the electric charges may as well be a reflection of the Caster's state of mind, From a state of disorder to one of order, they surge toward a common destination, in the end gathering in one spot and releasing a brilliant glow.
On the deck, the winds blowing from all directions brush his hair. With how vividly brilliant the sometimes introverted, timid boy looks this very moment, it's as though he himself, and not the staff, is letting out that radiant glow.
