Kuma’s dedication to Luffy is a testament to his loyalty as a member of the Revolutionary Army and deep respect for the Sun God Nika. Kuma has realized that Luffy is indeed Nika because he has witnessed Luffy’s extraordinary rubber powers, which are intrinsically linked to Nika. Therefore, Kuma has made every effort to protect Luffy over time.
In other words, Kuma sent Luffy to Amazon Lily because he believed it to be the safest place to ensure the survival of the future of the world. The relationship between Luffy and the government has become increasingly strained, especially after Luffy struck the Celestial Dragon. Kuma recognized that Luffy needed a safe haven, a place where the government would never think to look.
Amazon Lily is an island ruled by a powerful female monarch, who always holds disdain for men and a military force that even the most seasoned warriors must be cautious of; it is the perfect hideout.
Luffy and the World Government: Tensions Rising

Kuma firmly believes that Luffy will somehow represent the ideals of freedom and resist the oppressive pressures of Nika. By dispersing the impact of the Straw Hat Pirates to various locations, Kuma has ensured that Luffy can maintain a significant distance from the imminent threats posed by the World Government and prepare for the challenges ahead.
Silver Rayleigh, the right-hand man of the legendary Pirate King Gol D. Roger, plays a crucial role during this period. He also informs Luffy about the safety of the members within the Straw Hat Pirates. At Amazon Lily, Rayleigh trained Luffy on how to utilize Haki, an essential skill for confronting the challenges of the New World.
Thus, Kuma’s choice to send Luffy to this location was a strategic decision, providing Luffy with an opportunity to strengthen himself and get ready for the impending dangers.
In the long run, Luffy’s stay in Amazon Lily could be a calculated move by Kuma aimed at forging a potential alliance between the Straw Hat Pirates and the Kuja tribe. As the storyline approaches its climax and details about Egghead Island come to light, this alliance could prove significant. Boa Hancock’s affection for Luffy indicates that the Kuja tribe may stand alongside the Straw Hats in future battles.
