It occurred to me this should probably go here. With Regards to Ruka, you don’t have to walk on eggshells really. It’s pretty safe to assume Sal will automatically and instinctively either shield her eyes or ears for anything. He’s very protective of her. And she is essentially blind to any bad in the world. Lol And she might be brave around him, but is a bit of a pacifist, unless her dad needs help for any reason.
I'm PST, so it's late and I'm going to go to bed. If anyone wants to interact with the recently-arrived spectating mahou shoujo, feel free to @ me, but I won't have a reply until tomorrow morning - about 12 or so hours from now lol.
