Hinata Sakaguchi/Relationships

Luminous Valentine
Subordinate of Luminous and genuinely thinks very highly of her. Hinata will do anything Luminous says and in return, Hinata uses Luminous's power through Holy Magic. Despite Luminous being a vampire Demon Lord, Hinata worships her as the one true God; their ideals match well.

Jura Tempest Federation
Hinata, as a representative of the Holy Empire Ruberios, is first hostile towards Tempest due to their doctrine against monsters. After sending their military and the elite crusaders led by Hinata, their mission of annihilating Tempest ultimately fails and they end up changing the doctrine to include monsters of Tempest. Hinata as a former Japanese, loves to indulge in the many luxuries Tempest provides. She doesn't hesitate to make excuses as long as her visit in Tempest is extended.

Rimuru Tempest
At first, she loathed Rimuru for the simple fact that he was a monster and his existence went against the teachings of the Church while also being fooled by the Eastern Empire merchants into believing that he had killed Shizu. Rimuru was wary of Hinata after learning about her, but also desired to meet her because she was Shizue's student. She tried to ambush and kill Rimuru but failed when Rimuru faked his death in their fight. Even after learning the fact that Rimuru not only survived but was telling the truth to her about being a Reincarnated Otherworlder who did not murder Shizue, she regretted the situation where she neither managed to build good relations, nor eliminate the threat, but instead had given a bad first impression to Rimuru who survived and became much stronger. It didn't help her case with the fact Hinata refused to give Rimuru a chance to tell his side of the story. During their second battle, it was revealed that their conflicts were all orchestrated by the Western Holy Church's Seven Luminaries and the string-pullers of the Eastern Merchants that sold Hinata false information. After the battle ended and three out of the seven Luminaries tried to make use of Rimuru's and Hinata's exhaustion to get rid of both of them, Hinata took an attack meant for Rimuru. Rimuru was able to block all their follow-up attacks and was about to counter-attack when Hinata's boss, the Demon Lord Luminous Valentine appeared and after some negotiations there was finally peace between Rimuru and Hinata. When Hinata blocked an attack aimed at Chloe with her body, it triggered the activation of Chloe's Time Travel skill, which pulled Hinata's soul into Chloe's body who then traveled 2000 years into the past.

Later in the series, Hinata begins to see Rimuru as a father figure to her, saying that she pursued the shadow of her father in him, and blushing whenever he praises her.

Veldora Tempest
Hinata first met the Storm Dragon in person during a trip to Tempest. She was stunned Luminous was giving the dragon a beating; having mistaken the vampire's utter distain of Veldora as fear.

While facing the trials of Lamrys' labyrinth, the Saint managed to reach the bottom level where she confronted Veldora, but was unable to defeat him. Despite her decisive loss, the two would fight again after Hinata's soul was fused with Chloe and sent into the past. Indeed, Hinata was in control of Chloe's body when the hero defeated Veldora and sealed him inside the cave where the True Dragon would encounter Rimuru many centuries later. Upon returning to the present, Hinata and Chloe recount the events of their time-traveling expedition. Veldora realizes with shock the true nature of the hero who defeated him. Hinata taunts him with her victory, nearly resulting in a rematch, but the situation is diffused by Rimuru. So far, Veldora is the only person whom Hinata expresses a petty and competitive nature. As of now both have defeated the other a single time, thus their score remains unsettled.

Shizue Izawa

 * Hinata deeply respected Shizue as a mentor and friend.

Yuuki Kagurazaka

 * Hinata and Yuuki exchange intelligence with each other from time to time. After a reunion with Rimuru in Tempest, she came to the conclusion that Yuuki was behind the false information she received of Rimuru and Tempest and became suspicious of him.
