The Five Elders are immortal, and can recover even after their heads are cut off? One strike from a Bankai Zanpakuto will teach you to behave!

Saint Mars: Damn it! Why did Saturn die just like that?!

The Five Elders cry out in terror: Lord Imu, save us!

Imu: Compared to Joy Boy, Veyce is the real thorn in my side!

The Pirate Empress: Veyce, the emperor of Amazon Lily!

Robin and Nami: Sorry, Luffy.

Yoruichi, Rangiku, Flower Mom, Sister Bei, Nelliel, and the beauties of the Soul Reapers! Erza and Irene, mother and daughter, Kaguya, and the shame of the succubi...
