It's beginning to become very depressing that I have so many unknown cosplays in Cosplay Holic. Maybe I should fly to Japan and stay there for a while to get myself up-to-date.
Anyway! I’m sure you can tell from all the details that the cosplayer worked really hard on her costume for Comiket 2010. I wonder if she’s from a fighting game or a fantasy manga? Thanks again to Ingrid for the photo!
EDIT: Thanks to vza004 for letting me know this is Luca Trulyworth from Ar tonelico II: Melody of Metafalica!
