Umu...

Hiiro is in deep thought.

Maybe he's pondering the secrets of the Universe? Maybe he's thinking about omurice! Maybe his buddy Tetora Nagumo, "Captain" of the karate club, or why the sky is blue, or how to tell Aira marshmallows and chocolate aren't breakfast food. Maybe he's thinking about the little legs of a hamster running on a hamster wheel, or trying to find an answer to a pretty straightforward question he was asked when he was, like, 5. Maybe it's something else entirely.

Whatever it is, Hiiro hasn't noticed you yet!-- Just kidding, he sensed you ages ago.

Hello! He speaks loudly, happily, and with confidence that shows he is clearly not shy at all.
