I like calling Gudao Ritsuka and Gudako Ritsuko. It's my headcanon and I stick to it.
Since I'm not too keen with the way Prisma had taken (I've grown disinterested since 3rei started and the Ainsworths appeared) *or* the official Grand Order manga (except Riyo's, but that's its own thing) but I really really liked this, I can't help but thinking it's a shame they didn't take Hiroyama off Prisma and made him draw the GO manga adaptation instead. He nails all the characters and when he wants to he can mix silliness and impressive action and balance them well.
