Yes, this will 100% end as Yuri, but not yuri harem. Aria ends up with Carla (renamed White after the events) in a sort of strange relation where Carla is like "Well, you saved my life, you broke me, you buy me". They also basically own a cat together (a cat that can take on a dragon mind you), and just go about their lives living as they always have, adventuring, murdering enemies, saving people, spending time with their cat (fighting impossibly strong things). You know, normal yuri couple things.
