I know you just want to shrink Kino further and cradle her in your arms, you don't have to hide it.
Don't know about Cal, actually. Kino and Ai do turn out to be adorable tomboys. I have yet to finish Kino's Journey, I don't know why. It's a very sweet fairy tale series.
My avatar is General Vamp from Astro Fighter Sunred. It's a gag-based mildly comedic anime about a transforming masked hero fighting monsters, except the hero is a violent, trash-talking jackass and the villains are otherwise polite contributors to society. Vamp's the villains' general, except you'd think he's just a really nice grandpa with the weirdest face.
