"Luminance"

"Three polyamorous heroes are called to action to defend their home from a malevolent entity who wants to separate them. After reconciling after some time spent apart, the three protagonists finally face down the black cat that has subtly been pulling the strings of their relationship for the last few months. They face off in a confrontation against it with the fate of the world at stake, but using their combined magical skill they defeat the demon and get to return home together for a celebratory movie night."
