Dramatic Log

Defeat the Animal Kingdom Pirates.

Proceed to the target area and learn some aerial attacks.

Complete the requirements to destroy the barrier.

Advance on the map and defeat the Samurai Chief and company.

Defeat the three Samurai Chiefs.

Big Mom will appear. You will be required to perform one of each special move and defeat the Samurai Chiefs.

Once you defeat them, destroy the barrier.

Advance to fight Big Mom. Deal with this giant enemy, try dodging her attacks and save some special moves for when she is stunned.

After you deplete more than half of her life gauge, a cutscene (a non-interactive cinematic the game plays automatically) will trigger, and Kaido will enter the battlefield.

He can deal a lot of damage with his attacks but he is slow, so you have plenty of time to dodge him.

After you deplete about 2/3 of his HP a cutscene will trigger and the prologue will end.
