After the Marineford incident, there was a major power shift within the Marines. Akainu becomes the new commander of the Fleet, while Aokiji resigns from the Marines altogether, leaving Kizaru as the only remaining lawyer. To fill the void left by Akainu and Aokiji, two Marines were promoted to become the new commanders.
They are the master swordsman Fujitora and the woodman Ryokugyu. However, it does not take long to realize that the two new admirals, as well as Kizaru, cannot be different from each other. This difference in personality and outlook led to a unique exchange between the three naval commanders. Kizaru is someone who views being a diver as nothing more than a career. It started from the bottom and slowly went up. He knows his duty as a naval commander, so he will not let his personal feelings get in the way of his mission. As long as the order comes from above, he will do it to the best of his ability, regardless of the method. Like any dedicated employee who puts the needs of his company before those of the customer, Kizaru’s loyalty lies with the company known as the Marines more than the people. This means that he will not hesitate to wreak havoc and kill many innocent people because of his mission, which is exactly what he did in the Sabaody Archipelago. This also means that he will hunt down and kill anyone if the Marines ask him, even if that person is someone he considers a long-time friend, which makes Dr. Vegapunk now.
That said, Kizaru is a laid-back man who hates to do anything unless told to do so by those on top. He prefers to stick to drinking a good cup of tea in his room. And even though he had known the other admirals, including Akainu, for decades, he considered them only colleagues. He will not go out of his way to help them in their time of need. Instead, he will fight against them if their leaders ask him to do so. It will hurt, but he will still do the job to the best of his ability.
Fujitora the rebel
In more ways than one, Fujitora is the opposite of Kizaru. For Fujitora, being a waterman literally means being a civil servant. Therefore, it is the responsibility of the Marines, especially the admiral, to do everything they can to ensure the safety and prosperity of the citizens of the world. In his mind, the good of the people comes first, and he is only a humble servant who is given the opportunity and power to serve the people.
This kind of rational thinking often leads to conflict with his superiors and superiors. After all, in order to do what he thinks will be best for the people, he will not hesitate to abandon his original mission or even ignore direct orders from his superiors. This is exactly what happened in Dressrosa when he let the Straw Hats go, or when he deliberately kept him from knowing when the revolutionaries freed the slaves in the holy land of Marie Geoise. Fujitora uses the power and influence of a captain to pursue his justice, which often goes against what the World Government wants to do. Needless to say, this stubbornness and defiance often lead to major conflicts between him and Fleet Admiral Akainu. As for his relationship with the other leaders, it was difficult to talk to Kizaru, but Fujitora would occasionally have a simple conversation with Ryokugyu. And unlike Kizaru, he will refuse any order to kill his fellow leaders, unless they become a threat to the people. Ryokugyu the fanatic
If Kizaru follows the rules while Fujitora only does what he wants, Ryokugyu is the type who always tries to do more than necessary. He will strive to exceed the expectations of his superiors in any mission entrusted to him. This enthusiastic nature does not come from his desire to do the best work like Kizaru or a high opinion like Fujitora. This comes from a much simpler reason. Ryokugyu honors Fleet Admiral Akainu.
In Ryokugyu’s mind, Akainu is the perfect representation of what a ship should be. A stoic, upright and ruthless person who will do anything to catch the villain. Because of this exaggerated attraction, Ryokugyu will do whatever he can to impress Akainu. He will also do things without being ordered to do it, like the time he attacked the newly liberated city of Wano to capture the Straw Hat Pirates, which he thought would please Akainu a lot.
