I will not spoil anything, so I will just say you can get Bad End 2 if the fight scene ends in a draw. If the choices you pick cause both you and your ''enemy'' to die. Since you played the game I'm sure you know what I'm talking about.
If u go with Anya at first, you will find a boar at the way, and then the rules will be explained for the fight... if u end it in a draw u get ending 2!
