"What happened earlier? The sea shook for so long that I thought a massive tsunami was about to hit!"
On the island closest to the Sabaody Archipelago, several women were walking down the street.
Among them were Nami, Robin, little Perona, and Kalifa.
Beside Kalifa stood a stunning long-legged woman with long green hair, dressed in a white nurse's uniform and black stockings. She was Alpha, Kalifa's younger sister.
The reason Oak had arrived at the Sabaody Archipelago so late, even later than Straw Hat Luffy, was because of her. Alpha, a Cipher Pol No. 8 agent who had once been assigned to monitor Bonney, had been tricked out by her sister and subsequently controlled by Oak's Vampire ability, becoming a "Blood Servant."
Although Oak's physical constitution meant he hardly ever got sick and had no need for medical care, Alpha was still assigned as his personal nurse.
As the women walked together, Nami complained about how their island and the surrounding waters had been trembling slightly throughout the previous day. She had worried all day that an earthquake or tsunami would destroy the entire island they were on.
After hearing that, Robin glanced in the direction of the Sabaody Archipelago. She had a feeling that yesterday's disturbances were definitely related to Oak.
Although Oak had said he was only going to the Sabaody Archipelago to find someone, with his troublemaking nature, he had most likely gotten into another fight there. And this time, his opponent might have been extremely powerful.
Robin's deduction was based on the fact that the disturbance had reached even their distant island.
It had to be said that her guess was quite accurate. Oak's battle with Imu yesterday had not only damaged the Sabaody Archipelago, but also affected a vast stretch of sea and islands
