Yuki's heartaxe falls and dissipates into nothing as she grabs the tea tray out of the air and spins with it into a carried flat position. She skips forward daintily, her tail flipping up, as she slips a foot in the way of the third guard dueling Keli. This sends the poor guard sprawling into the arms of her nearby compatriot, while Keli capitalizes on the suddenly unsupported third one and Seli finishes tying up her set into a lovely tapestry depicting the many methods for taming and herding sheep. 

As for the big guard, Yuki tiptoes up and gently offers her up her tea tray with one hand and a curtsy. "Excuse me, I think you dropped this, and you wouldn't want it to get dented, I'm sure." She does her best to give her voice the sort of lilt Eclair would in this situation. Not that she's doing exactly as Eclair would here (she imagines that if she were Eclair, she'd have already struck down all seven guards in a blinding flash, actually). 

She's not quite at that leve, but her heart axe materializes in her other hand as she releases the curtsy. Despite its heft, she has no trouble holding it out steadily with one hand so that it just ever so very gently caresses the surprised big guard in the chest. "Now, I think you'd like to tell us which cell my friend is in and then hand over your keys, right? And, free bonus, you get to decide if you want to help us out while conscious or unconscious. Stand still for conscious, or twitch aggressively for unconscious, okay?"

[Yuki chooses to entice the guard: 5+4+2=11. She will spend her string immediately to get the guard to help them, though our plucky narrator gets to decide whether that help is willing or takes the form of a useful map on the unconscious person]
