Summary:
Kaidou laments the damage his crew suffered during the raid, losing all of his top officers and his castle being destroyed by the battle. He continues his fight with Luffy on the Skull Dome, and as Luffy is thrown into the air, he gets the idea to use the lightning in the sky.
Down inside the Skull Dome, the allied forces are separated and cornered by the spreading fires. Chopper reunites with Nami and Tama, but is unable to find any other allies or fight the fires. Brook, Robin, Apoo, and Number Inbi are trapped in the basement, Sanji and the other women are trapped in the left brain tower, Usopp’s group, Franky, and Zoro are also trapped in the corridors, and the mink forces are trapped on the third floor. .
On the fourth floor, Raizo and Jinbe execute a plan to put out the flames. Using his Devil Fruit ability, Raizo summons a scroll that produces a huge amount of water. Then Jinbe uses the Fish-Man karate technique to control the flow of water and flood all parts of the Skull Dome, extinguishing the flames and saving the allied forces below.
However, outside of Onigashi, Yamato pressures Momonosuke to create Flame Clouds to support the island. As Kaidou’s power rapidly declines, the Flame Clouds he created weaken and are about to collapse. Momonosuke needs to create his own Flame Clouds before this happens, otherwise Onigashima will fall and hit the mainland.
