Cori is a sanitized Octoling who only 'escaped' from the metro years after everyone else left. She is reliant on Lumine, who found her passed out on a shore and offered her a place to stay, they've lived together ever since.

She tries to cover her face (usually with a mask) unless around people she really trusts, she uses it to try be as unnoticeable as possible, despite her condition.
She is very insecure about her sanitization, avoiding others and trying to hide it as much as she can when leaving her and Lumine's apartment.

Cori's right arm is badly scarred after an incident at Kamabo, the scar is visible along the side of her neck to her wrist, she experiences general muscle weakness in the area.
The bandages on top of her hoodie correspond to the more heavily impacted section that carries the marbling of sanitized ink, they apply pressure to try alleviate the pain in the area.
Because of this injury, she cannot wield many weapons nor do many things with her arm.
She tries to hide and cover up her scar in hopes nobody finds it.

Her memories are mostly lost, as a majority of her mem cakes were destroyed at Kamabo by her superiors. But she still feels a faint familiarity with things even if she cannot grasp them.
Some evidence of her old identity can also still be seen in her behaviour.

She has feelings for Lumine, but has no clue how to express them, with it often manifesting subconsciously as her tentacles curl when nearby her and she leans towards her/rests on her shoulder at times.

Appearance

Her tentacles are an abnormally long tentacurls style (just below shoulder length) and have a habit of curling up whenever Cori feels stressed or threatened in any way. (the movement is involuntary, it's just like blushing) She cannot exert any control on their movement either.
They are a blue>green>dark green gradient, rather than the usual blue>yellow-green gradient of sanitized individuals.

The gear she often wears wasn't originally hers, she took it after awakening in an abandoned part of Kamabo Co.'s facilities.
The hoodie has a scratched-off Kamabo logo to the left of the zipper with her boots being the octoleet boots which she found along with the hoodie.
The exception to this are her goggles which were a gift from Lumine, she values them greatly and usually carries them around with her if she isn't wearing them

Her pupils are white and have a dim glow to them, her irises are, from top to bottom, a lime green>turqoise>light blue gradient, her sclera are a very dark green, resembling the sanitized octarians more than octolings. Her glowing pupils are the result of an improper sanitization.

Cori is slightly shorter than other inkfish due to being underground and undernourished in the metro for a long time.
