Sounds | The main appeal of the anime (at least to me) is hearing Yuzuyu talk (her voice actress, Miyuu Tsuzurahara, is 9 years old), so here are some clips of her and as well as of other characters.
All of these are in mp3 format.
º Yuzuyu's onigiri "song"
She sings it during episode 2 because she's happy Kippei made her rice balls for lunch (or so she thinks...). When Kippei tells her they need to hurry because they're late, Yuzuyu just sings faster.
º "Baka ka omae wa?"
Neechan asking Kippei if he's an idiot...
º "Yuzuyu"
Yuzuyu introduces herself to Kippei (when he thinks she's Neechan after she's somehow shrunk).
º "Yuzu onigiri daisuki da yo!"
"Yuzu loves rice balls!"
º Kippei-mama
Neechan calling Kippei "Kippei-mama" and telling him he'll be late.
