Kaku

Kaku is a masked agent of CP0. He was previously an assassin of CP9. Kaku is a young man, who has big black eyes with 3 eyelashes on top of his eye, and a long nose similar to Usopp's, only rectangular in shape. He has short orange hair. As a CP0 agent, Kaku now wears an all-white suit, along with a top hat and a yellow tie. While on duty, he sometimes wears a tribal mask with a long beard as well as a protruding shape that fits around his nose.Despite his role as an enemy of the Straw Hats, Kaku is surprisingly honest. Even to his enemies he doesn't lie to them. Though he does not seem to take insults well. He is most sensitive when he is in his hybrid giraffe/human form. He also talks like an older man, as remarked by several characters, despite being only 23 years old. Kaku can have a cold and dispassionate personality sometimes when working. Despite this, he often taunts his opponents during battle. He also seems to place a chance to fight over easy accomplishment of a mission. Also Kaku seems to be the only one of the four assassins undercover in Water 7 who expressed some regret that he could not go back to the way he had been living for the last five years. He seemed truly happy there. Kaku has a childish side, being openly excited by the futurist wonders on Egghead Island. When seeing Luffy at Egghead, Kaku is shown to be cautious and very obedient when he tried to tell Lucci to not fight Luffy without permission from the World Government. Kaku is not above speaking his mind about what he thinks of them. As a current masked agent of CP0, the strongest intelligence agency of Cipher Pol, and formerly the second strongest member of CP9, Kaku is a formidable and valued agent of the World Government. Kaku can also function as a lie detector. He demonstrated the ability to tell whether something is true or not by feeling a person's wrist and then tell the truth by determining the speed of the person's pulse From his training as a Rokushiki master, Kaku has worked hard to develop his tremendous physical power since childhood and could match the formidable Roronoa Zoro in terms of strength. He has incredible speed and agility, being able to move extremely fast and leap from buildings from amazing heights and distances without a scratch, showing extraordinary leg strength. Kaku is a highly skilled and creative combatant. A highly intelligent and cunning individual, Kaku was able able to become a master shipwright within a 5-year period merely as a form of espionage and surveillance over his "boss" Iceburg.When he returned to Enies Lobby, Kaku ate the Ushi Ushi no Mi, Model: Giraffe, a Zoan-type Devil Fruit given by his boss, Spandam, which allows him to transform into a giraffe-human hybrid and a full giraffe at will, massively increasing his strength, weight, and durability, while also lending him the benefits of unusual features, such as the greater reach afforded by the long neck of a giraffeKaku has also achieved Devil Fruit Awakening, letting him assume a new, much more powerful hybrid form, which greatly enhances his physical strength, speed, as well as his recovery rate. Unlike most Awakened Zoans, Kaku's personality was not overtaken by the animal nature of the Devil Fruit. In his awakened form, his already long giraffe neck becomes longer and serpentine-like.Kaku possesses the ability to use Busoshoku Haki.

Surprised to find out that the royal he had to corrupt was his old childhood friend
