I know it's a crossover/cosplay but don't know the other source. Please, help.

Sheryl Nome/Macross Frontier ?

It's already been tagged: Chocolate Misu, Bakuretsu Hunters.

Yep~. Gotta love Chocolate. (I didn't know it was crossover from the thumbnail almost.)

Oh my. A Bakuretsu Hunter fanart on Danbooru? That was unexpected. I was a big fan of Bakuretsu Hunter when it aired like 10... oh no. Exactly 10 years ago. I was only 12 years old.. AND THAT LEFT ME A TRAUMATIC EXPERIENCE and now I am a perverted person.

Anyway it's really nice to re-discover my childhood memories....
