My partner and I cosplayed the Vocaloid characters Gakupo Kamui and Luka Megurine respectively. Vocaloid is a singing synthesizer. It is neither a manga or an anime.
Thank you Glenn for inviting us! I got the chance to cosplay my favorite Vocaloid that day with an awesome awesome Luka as a partner. My friends commented that I really looked like a man on these photos. Crossplaying is a success!
