Firstly, why are all but 1 of the party facing away from the enemy?
And more importantly... are the enemy killer squirrels? :O
That was supposed to be some kind of badass Samurai stance.. or maybe he was after Riou's butt.. or waiting for Sierra to spank his own butt. The geniuses at Konami left it open to interpretation.
Some of those squirrels are actually secret playable characters :)
