This is Rin (& Alpha) from Yume Kira Dream Shoppe. Yes, it's a dumb title, but it's a really cute and.. well.. sweet manga. Mostly about Rin granting wishes and couples getting together, and while I'm not precisely a big fan of romance, Rin and Alpha were too fantastic to pass up.
Anyway, it's kind of his job to grant wishes, so he's been around since forever. Not that it's felt like a long time for him. Anyway, even though his shop that's only accessible through certain means, he'll be settling down in one in Los Angeles (called, very simply, 'The Dream Shop'). So come visit; he loves visitors.
Oh yeah. And Rin's.. not a guy. He's not a girl, either. Actually, no one really knows what he is. I think Alpha assumes he's both. So feel free to call him 'her', too, because it's.. honestly just as accurate.
