^ I'd say it starts really gay, then gets toned down a little later on. They are still like a family with a daughter and Riko acts like she's Mirai's wife sometimes. Nothing explicit...yet.
Weird that people think Ruby looks male when she's wearing the Official Dyke Uniform. If I had a yen for every woman in a gay bar I've seen dressed pretty much exactly like that, well...I'd have a bunch of yen.
