Hinata Sakaguchi/Chronology

Demon Lord Awakening Arc
Hinata was first seen when a servant requests an audience to inform her that the slime Rimuru was building a nation of monsters in the middle of the Great Jura Forest. She quickly assesses the threat level and decided that Rimuru and their country needs to be destroyed. Being influenced by misinformation from an Eastern Merchant, she decided to kill the monster who had supposedly killed Shizu, the one person she respected. After defeating Rimuru in battle, she returns to Ruberios to await the destruction of the Tempest Federation, while also believing that she had successfully avenged her mentor. Little did she realize, whom she defeated was actually a Body Double and that the real Rimuru was hiding nearby waiting for her to leave. When Laplace came to Ruberios, she threatened to attack him, forcing him to leave.

Saint-Monster Confrontation Arc
Upon discovering the obliteration of the Falmuth army, Veldora's subsequent revival, Rimuru's recognition as a Demon Lord, and she had been tricked by the latter, she calls a conference within the Church to decide what to do next. During the conference, she learns that Rimuru has sent an invitation to duel her one-on-one, and she decided to go despite the suspiciously short message.

Whilst leaving the kingdom, the Clerics of the Seven Luminaries present her with a massive sword named the 'Dragon Buster' to aid her, which she accepted despite her suspicions.

She took two weeks to travel on foot from Ruberios to Tempest, and during that time sees the level of infrastructure developed by Tempest. Impressed by the focus on comfort to humans, she decides to negotiate with Rimuru as best she can.

However, upon arriving she finds that about a hundred elite soldiers on orders from the Seven Luminaries have arrived without her knowledge, alongside her own party which was utterly insistent on coming with her to a one-on-one duel. Rimuru believes that this attack was her plan and ironically refuses to listen to her, forcing the two to duel. The two fight to a complete standstill, but ultimately Hinata (as she, as a human, would lose all her stamina if the duel continued) suggested that if Rimuru can survive her final attack, then she would consider them the victor. Because neither truly wish to kill each other, Rimuru agreed, and Hinata used her ultimate technique Melt Slash on them. Raphael then secretly made a copy of and then sacrificed the Ultimate Skill Beelzebuth in order to counter it, and Rimuru emerges as the victor, though with 70% of his magicules drained during the process. Suddenly, the sword 'Dragon Buster' exploded and a heat ray penetrated Hinata's chest, severely injuring her. While Rimuru was preoccupied with trying to save her life despite his low magicule count, two of the Seven Luminaries showed up and Garde revealed himself to be an imposter faked by the Luminary of Mars, Ars. Intending to kill everyone on site, they released their pre-prepared Trinity Disintegration, but were fully blocked by Rimuru's "Absolute Defense". Suddenly, Valentine (aka Luminous, god of the Western Holy Church) appeared, healing Hinata and disposing of the Luminaries for defying her.

After the battle, Hinata and Rimuru made up and parted on good terms, with the Western Holy Church agreeing to spread the doctrine that the kingdom of Tempest is made of harmless monsters and Ruberios signing a non-aggression treaty with Tempest.
