Trigun, Vol. 7: Puppet Masters - Region 1 DVD

Vash leaps into the heart of the storm and leads Wolfwood to the space ship that failed to crash. Unfortunately, the Gung-ho Guns have also invaded paradise with two purposes - destroy a sanctuary for humans, and to inflict as much pain to Vash as possible. Wolfwood chooses to side with Vash, but questions his ability to win - will Wolfwood walk the path of destruction again?!
