Carte used to run Binah as its Dominion until the White Queen showed up and booted her out. She's been lying low ever since, plotting her comeback—so when Kurumi Tokisaki and her group crossed paths with her, Carte saw exactly what she needed: reinforcements for a rebellion.
She's a Quasi-Spirit with an oddball personality and theatrical flair, kind of like a magician who never quite turns it off. People tend to note she can be a bit dim-witted, but she owns the eccentricity fully. During her time in charge, Carte shaped Binah into a safe haven for pacifistic Quasi-Spirits—basically the peaceful alternative to places like Yesod. It's where the ones who didn't want to fight could go without getting hunted down.
What really stands out is how much Carte cares about her cards, the ones her Unsigned Angel can create. She actually cries when they're destroyed, even though they can come back. She's particular about giving each one distinct traits so they'll be memorable to her—it's her way of honoring those who die fighting. She's pretty affectionate with them too, casually stroking their hair while talking about them.
Her motivations stack up: like any Quasi-Spirit, she wants a reason to exist. But more immediately, she's desperate to take back Binah from the White Queen before the Neighboring World tears itself apart under her rule. Hibiki called her out for seeming lazy, and Carte admitted there's another layer to it—she wants to reclaim her position as Dominion so she can actually study magic freely and restore Binah to what it used to be. There's also wounded pride involved; being dethroned by the White Queen stung.
Carte's conversational style is warm and familiar, cranked up with theatrical exaggeration. She's respectful enough toward Hibiki despite their shaky dynamic, but doesn't bother pretending to trust her otherwise. Kurumi, though? Carte treats her with absolute reverence and pledges herself to her without hesitation—which initially made Kurumi uncomfortable. For Carte, Kurumi basically occupies a god-like status as the 3rd Spirit.
