Yuuki Kagurazaka/Relationships

Moderate Harlequin Alliance
Yuuki's closest allies and cherished friends. He has absolute trust in them and relies on them for various tasks.
 * Kagali
 * Despite Kagali summoning Yuuki against his will and trying to kill him, Yuuki saw Kagali for what she was; someone in need of help. He allowed her to rest within his body and worked towards her resurrection, with the two becoming close allies and friends when they found they shared the same ideals. Kagali is the person closest to Yuuki's heart and the one he trusts more than anyone else. Even his innermost secrets, including his Mammon Ultimate Skill, are things he shares freely with her.


 * Laplace
 * Laplace is someone that holds Yuuki's utmost respect, being the person he trusts the most when it comes to field operations. The two of them have a tacit understanding, knowing exactly what the other is thinking without the need for words.


 * Clayman
 * One of Yuuki's closest friends and someone whose power and influence proved invaluable to Yuuki's ambitions. Though the two rarely had the chance to meet in person, they often exchanged talks over drinks. After Kagali, Clayman can be considered the first subordinate Yuuki ever obtained. Clayman's death hit Yuuki harshly, blaming his own naivety and inaction as the cause. Even after finding out about Clayman being controlled by Tatsuya Kondou, Yuuki still blamed himself for failing to notice it and writing off Clayman's strange behavior as stress-induced.


 * Footman
 * Though Yuuki originally held reservations about Footman going out of control and acting on his own, eventually Yuuki realized this was nothing to worry about. Footman is someone that Yuuki can trust to put aside his emotions and focus on the task at hand, showing just how loyal Footman is to him.


 * Tear
 * TBA

Freedom Academy

 * Shizu
 * Yuuki's mentor and a figure close to that of an adoptive mother for him that took the responsibility of raising him from the age of 12. The vast influence and connections she had proved invaluable in establishing the Free Guild, acting as his close assistant for many years. Though we have yet to see his genuine reaction to Shizu's death, from what we've seen it was a devastating loss for him. Though he ultimately understood Shizu's wishes and the true reason behind her death after meeting with Rimuru Tempest and hearing of her final moments.

Cerberus
An organization created by Yuuki with the assistance of Damrada. It controlled most of the underbelly of society from behind the scenes, with some of Yuuki's most trusted allies being present within its ranks.
 * Damrada
 * Second to only Kagali and Laplace, Damrada was among the most trusted of Yuuki's inner circle. It was with Damrada's help that Yuuki was able to overthrow Echidna and create Cerberus. Damrada was an essential part of Yuuki's plans, providing him funding, managing Cerberus, and allowing him to move freely away from the influence of the Rosso Clan.


 * Vega
 * Vega was originally a being that Yuuki, alongside Shizu, was called in to subjugate. However, Yuuki realized the 10 year old's true nature and potential, sparing him in secret and leaving him in the care of Damrada. In time, Vega grew to become one of Yuuki's most trusted comrades as well as a powerful asset in battle.


 * Misha
 * TBA

Demon Lords

 * Rimuru Tempest
 * The relationship between Rimuru and Yuuki could be described as extremely messy. Their personal feelings towards each other is that of friendship and respect, but their political backgrounds and the interference of others often drives a wedge in it, which leads him to try and stop Rimuru to ensure that he doesn't become an uncontrollable problem, albeit never successfully. Though for a time Yuuki held a grudge against Rimuru for murdering Clayman, with the revelation of Clayman being turned evil by the mind control of Tatsuya Kondou, it appears to be considered water under the bridge. The two have yet to properly settle their differences personally, but they remain allies with compatible ideologies that work towards mutually beneficial goals.


 * Guy Crimson
 * Though Yuuki expected to one day come face to face with Guy in his quest to free the world from oppression, their meeting ended up happening far sooner than expected and the two squared off in a duel. It was this fight with Guy that made Yuuki realize his strength was insufficient to protect his friends, much less the world. The battle also exposed him to the existence of Ultimate Skills, which resulted in his obtaining of Mammon not long after. Though bitter that Guy had nearly killed him and his friends, Yuuki and Guy ultimately formed a mutually beneficial relationship of cooperation with Yuuki acting as one of Guy's pawns to oppose Rudra.


 * Leon Cromwell
 * As the one responsible for Kagali's death in the past and as the sworn enemy of Laplace and the other clowns, Leon is naturally someone that Yuuki doesn't have a good impression of. Yuuki entered into a relationship where he and Leon would use each other, acting as the representative of the Rosso Clan after pretending to be under Mariabell's control. This ends after the events of Hero Awakening.


 * Luminous Valentine
 * Luminous and her followers are among the greatest of threats that stood between Yuuki and his ideal world. The immense influence of the Church combined with its corruption and oppressive policies, all while claiming to be the singular force of good, made it one of Yuuki's primary targets.

Rosso Clan

 * Granbell Rosso
 * Due to Granbell taking the backseat and allowing Mariabell to run amok, Yuuki viewed him as a much smaller threat. This would ultimately end up being one of Yuuki's biggest mistakes. After the death of Mariabell, Yuuki and Granbell finally had an opportunity to speak face to face. Initially Yuuki wrote him off as an old fool holding on to his racist ideals of human superiority to the bitter end, but was enticed to cooperate with him by promises of a weapon that could be used to oppose the Demon Lords. This was ultimately a trap, as the being Yuuki unleashed was an uncontrollable being of pure evil. Due to being duped by Granbell and his lies, Yuuki lost his foothold in the western nations and a great deal of trust. Ultimately Granbell ended up being just as big of a thorn in his side as Mariabell was, if not even more of one.


 * Johann Rostia
 * As the member of the Five Elders that was responsible for managing the Council of the West, Johann and Yuuki naturally share a long and colorful history together. It was Johann that Yuuki often had to negotiate with on the matter of the Free Guild's funding. While Yuuki pretended to be under Mariabell's control, Johann was his main contact with the Rosso Clan and the person Yuuki was required to report his activities to. As a result, Johann was naturally aware of Yuuki's connection to Clayman and other intimate details of Yuuki's plans.


 * Mariabell Rosso
 * Mariabell stood as a direct antithesis to Yuuki's beliefs, being his greatest enemy for almost his entire time in the Central World. Due to the immense influence she possessed as the heir to the Rosso Clan, Mariabell was able to oppose Yuuki's efforts for a free and fair world at every corner. It was only with careful preparation and deliberation after many years that Yuuki decided to take her life as well as her Greed Unique Skill.

Eastern Empire

 * Gadra
 * Though not a direct subordinate of Yuuki, Gadra is one of Yuuki's greatest allies and a close friend. Without the help of Gadra, it would've been significantly harder for Yuuki to manuever within the empire and set up his coup. Gadra also helps serve as a bridge between Yuuki and Rimuru in lieu of more formal communications.


 * Mai Furuki
 * TBA


 * Rudra
 * TBA


 * Tatsuya Kondou
 * TBA

Other

 * Hinata Sakaguchi
 * As a fellow student of Shizu, Hinata and Yuuki studied together for a period of time and formed a loose friendship. Though their conflicting ideologies makes true comradarie between the two next to impossible, they still respect the strength of each other and meet up when they both have free time in order to exchange information.
