"Don't expect beauty out of battle. Don't expect virtue in death. Don't think that only your life is at stake. If you want to protect the ones you should protect, you should attack your enemy from the back." --Sōsuke Aizen

"If your comrade is being defeated, you should see it as an opportunity. Rather than standing in the way, you should stab the enemy in the back. And if the enemy is so far above your level that you cannot even manage that... then you should let your comrade die. That is the way of the Onmitsukidō."
