It could be said that all the blood in the body of a Death God surpassing captain level was needed to unleash a Final Getsuga Tenshō!
Of course, the blood required had to come from within a Death God's body! Blood created through Spiritual Pressure, like Retsu Unohana's, simply could not ignite Isshin Kurosaki's Blood Moon!

"Pfft..."
As he spoke, the Captain-Commander gripped the blade and
