Who is this mystery boy? He's certainly not human, but even the goddess Belldandy can't tell if he's a god, a demon, or something in between. But one thing's for sure: he's a wizard at manipulating people; he's even gotten the hard-bitten Chihiro wrapped around his finger at Whirlwind Motorcycles. So why is it that Keiichi seems to be the only person who seems suspicious? Especially when the little boy asks if he can spend the night -- with Belldandy?!
