Well I was going to tell you all what the first rule is, but turns out I can't talk about it. Huh. Who knew sharks were so secretive about their clubs?
Well regardless, here's a picture of Vishka beating the everloving crap out of a member of the aformentioned not-talking-about club. For what reason? Who knows? Presumably he made an unwelcome pass at her, or commented on her masculine looks, or messed up her hair, or spilled her drink, or looked at her funny, or breathed out loud... Wow, she really needs to work on her temper.
An awesome picture by the fantastic Neodokuro. If you're not watching them already (why not?!) go do so, and check out their awesome Tumblr account where all their newest art gets uploaded; links on their page!
