Cassper (Armizuki)

Cassper, also known as Jasey, Armizuki or Kasper, is the ship name of Kasandra "Casey" Armitage-Scieszka and Kuragari "Jasper" Suzuki.

Origins
Their relationship started in underworld training, where little is known other than Armitage talking about how good of friends they were, with Suzuki looking confused. This is speculated by fans to mean either hatred or previous feelings, with the former being more in character, as she did canonically call him a "jeczaca kurweko." which translates to "whiny bitch", in Polish, "Słuchaj, jęcząca kurewko." However, he explains that he learned Polish "for fun" to talk to her.
