The scene is a sudden shower of sparkly rainbow fireworks, accompanied by no sound at all save for the thump of air caused by the annoyed flicking of a leopard's bushy tail. 

Yuki sighs and pulls her heart axe out again, slowly and carefully, as she stands by the window and looks out at the snow. She pulls upon it, and it seems to thin in the center and almost stretch like someone blowing glass, but then it shatters again into a thousand rainbow sparks that vanish into the air. 

"Damn it!" she says, putting a hand on the glass and taking a break. "When you said that the whole trick is reimagining your heart, I really did think it would be easy. Oh, all I have to do is imagine my heart manifesting into two pieces. But that sounds like a broken heart, and I've never really had a broken heart. High school flings don't count and when I try to think of how I felt breaking up with my last girlfriend all I get is this shower of sparks anyway. I was kind of hoping that it was gonna be like the Matrix and if I could just understand the right reality, then I could do whatever with it. But you weren't kidding when you said I could learn the trick but I wouldn't be able to do it, huh?"

Yuki sighs and rubs her head back and forth against the cool glass. It felt so nice feeling the cool, solid window against her fluffy ears. One of the coolest parts of being in Thellamie was having these way more sensitive kitty ears and the feeling of the glass against them was incredibly soothing. Maybe this is why cats back home always headbutted people back and forth. 

"What does it even mean that the natural shape of my heart is a big axe instead of something more subtle and finesse oriented? Why can't I pick? Or why didn't it just change automatically when I trained on a thin sword and my whole body got comfortable with those motions? Why doesn't wanting something new [i]with[/i] all my heart do the trick? Heartblades are really picky about which kind of heart they take account of is all I'm saying!"

She's not whining, really. She's just a little tired and there's something about trying this that makes her heart itself feel like it's getting a bit stretched out. She's not even sure if that was good or not, maybe it meant she was on the right track. Yuki picks up her head and looks over at her old friend supervising her and what she hopes is her new friend sipping hot cocoa. "Can you tell me what it's like for you, Eclair? Like, when you first learned to do this, to change up your heartblade to different forms, what were the feelings that let you change your heart this way?"
