The Marineford War is about to begin, and countless Marines have gathered at Marineford, preparing for a decisive battle against the Whitebeard Pirates! But just then, Luffy, Jinbe, and Ivankov, who were causing chaos in Impel Down, suddenly stopped. They had come across a colossal object placed at the entrance to the sixth level—a massive block of ice filled with seawater! And inside this ice block, a figure seemed to be floating! Who is this woman sealed inside?!

Jinbe the Sea Knight: I have heard that twenty years ago there was a Marine Admiral who, in a fit of rage, turned the first half of the Grand Line into a sea of ​​blood!

The Warring States of Buddha: In order to win this war, it seems we must release her from the "Sea Tower Ice Prison"!

Hero Garp: If she awakens, this war will be thrown into complete chaos!

Akainu: Sensei, are you finally waking up?!

Whitebeard: Oh dear, you Marines actually dared to release that demon! What a mess!

Kaido: You've finally appeared! I've been waiting for you for twenty years! Let's have a good fight!
