So, this is a crossover from Monster Hunter? Huh... I first thought that this was a crossover with something else, 'cause the similarity is uncanny: [link] The samurai-ness, hairstyle, the hat (sorta), and can't forget the pink! (FYI, the character is Captain Shunsui from the anime Bleach)
Hmm... I guess it's just their hairstyles that really speak to me; both Pinkie and Shunsui have naturally curly/bouncy hair, and it's been tied in a ponytail. They're also both dressed like a samurai, but that's pretty obvious. Must be the hair.
