Photographer and contributor, Bethany, also has no idea what series or game this cosplay is from, but she submitted the photo to me anyway. I’m impressed by all the details in the costume, and it makes me even more curious to know the character and the cosplayer behind the mask.
A little help please? Thanks again to Bethany for sending this in!
EDIT: Thanks to everyone who commented that this is Yoshimitsu from Soul Calibur III!
