Backstory
Despite being an only child, Paris's family frequently hung around Ijus' family when both cousins were born, the two seeming more like sisters as they latched to the other. Paris had always been the clingy one of the two, like a little sister always wanting to be at her side, even when her childhood was a short one; Early into her youth, Paris and her family passed away in an accident. Even if Ijus' family tried not to tell their young daughter yet, she'd found out Paris passed when she appeared before her as a ghost.
At first, Paris wasn't visible to her, crying to herself often that she'd become a lonely spirit. When constantly being around her enabled her to see ghosts, Paris was relieved, glad that even in her after life she could have Ijus with her. She wasn't that close to her parents in all honesty, Ijus truly considered her only family, especially when her parents didn't come back as ghosts with her. Watching her every milestone, protecting her, Paris was content seeing Ijus live her life and celebrate each good thing with her. As a child everything is excitable, but as they both grew up in different ways, the gap between them started to become apparent.
Paris wasn't the kindest towards others, spiteful towards girls envious of Ijus early in her school days. She haunted them, spooked them if they spoke badly of her cousin, but they couldn't see her. Correlating the supernatural events with the mention of Ijus, there was a brief time that she was picked on, the worst case scenario to Paris, but Ijus had the support of the boys around her. Around middle school, Paris watched Ijus grow close to boys and date a couple of them, flings that didn't last. When Ijus met Gingko however, another girl, the two were without a doubt made for each other. When they'd gotten married, moved in together, and so on, Paris had already become distant.
She could see that Gingko could see ghosts as well, but often hid herself to avoid her, the person who'd taken away the one most important to her. Spending most of her time wandering around, Paris did wish that she could have Ijus back at her side only, but was also aware that she deserved her own happiness without her. In denial that she could be in the way of it, Paris was open to any way of separating the couple, even if it meant running into the convoluted world of the Gods when she'd met Ephialtes. Suddenly hearing that Ijus was cursed by an evil God to pass away like she had early in her life, Paris blindly followed Ephialtes' instructions to prevent it.
Paris tricked Ijus into opening an urn with Chimare inside, hearing from Ephialtes that her release is vital to saving Ijus. Possessed by Chimare, Ijus's impending death was delayed, but separating the two become it's own hassle. Paris learned Ephialtes used the cousins to unseal their comrade, to move forward in a battle against Gods, but now they were roped up in it. Despite her intial anger over it, learning more about the circumstances, Paris agreed to help if ultimately they were getting revenge against the God that cursed her lineage's firstborn daughters to die young. Because of that God, the misery named Merikh, Paris had died.
Helping Ephialtes and Chimare to track down their sealed comrades, Paris looked for the Pandora's boxes herself. She'd come across other groups like Gingko's as she sought to get her wife back, and Isiktan's underlings like Matia. He was an insufferable person that often got in Paris' way, but he saw how she meant well under her prickly exterior. For a spirit to get involved in the matters of Gods, to save just one human, she truly didn't want to be alone in the afterlife. He was a spirit as well, working towards the safety of his sister, hoping that after everything is worked out, he could get along with Paris. At the moment she refuses his invitations to become friends, but if she's got a long afterlife ahead of her, she'll consider spending her eternity with someone else depending on the outcome of their goals.
