Rin is such a know-it-all like damn. Or maybe just Captain Obvious. She never knew you had to do a dance or whatever. Groovy in the kitchen. Not too groovy, though. Rin's always just excited about baking, rather than fussed. It's been a while, y'know. She was never informed on the kitchen being opened - It was only until ... Yeah. Baking is a daily routine for her. Tiny chef is really excited.
"...Heh, ahh, sorry! I-I'm just ... I've missed baking, that's all..."
Hey Mizuchi! Don't be mean to the tiny girl, geez! She just wants to bake. Actually, nah, be as mean as you want, she's used to it.
"...Oh? Ryuujin-san? M-Mizuchi? ... Mizuchi-niisan it is!"
She could've sworn she heard someone call him lesser Ryuu, but she chooses not to bring it up. Perhaps it's an inside joke or something. Mizuchi-niisan is perfect. She's going to call him that forever now. Rin loves nicknames.
"...Mizuchi-niisan is a surfer? Hmm..."
C'mon Rin, you know this guy! I mean, you've heard of him. Think about it, yo! Thinking, thinking...
"...Ah! Yes, I knew I recognised your name, I know you! One of my friends wants to be a sports person...An athlete. Well, you're a role model to my friend, niisan. She would be so jealous of me right now, ehe!"
She takes a sip of her ramune before realising she just finished the whole thing. Oh well! The tiny girl wanders over to the oven to check on the cake (which has barely been in the oven for more than five minutes). Time to wait for that cake to finish. Patience is a virtue, or something.
Then she can poison the surfer.
