>in-universe duos (possibly romantic?)
For Sonar and Malevola along with Punch-Up and Coupe, sure. Prism and Flambae are just pals with one another. A gay guy and a sassy black lady hyping each other up.

>The demon girl and the bat guy fuck.
They sleep around with other women too. Flambae is into men according to his dialogue. Yet again this game is extremely hetero, all things considered.
