Who's This Elf?

I hate it when I have all the free time and yet I feel like doing absolutely nothing. Though I managed to draw one of my ideas. (I have much more, lots of sketches in my sketchbook)
It's a bit messy sketch but I don't care. I like it as it is. I want to go into details with it, painting, texture, etc. hmm, maybe later, but that usually means never...ANYWAY

So yeah, who's this elf Julei-Zu is with? Go ahead and guess (ﾉ◕ヮ◕)ﾉ*:・ﾟ✧
hint: it's a non playable character that is the synonym of fascinating.
