We have posted about Mancoin's Krystal cosplay before. Since then, Brian sent me a few videos of Mancoin's Krystal cosplay at UniCon 2014. The first is Mancoin's on-stage performance with music, sound effects, and voice acting integrated into the act (Alternate Angles: 1, 2, 3). The second video, below, is a quick cellphone video of Krystal acting catty.
