"I’ve heard enough of your lies. Shizu was everything to me, and you stole her from this world. For that, your life is forfeit."

Hinata Sakaguchi is the leader of the Western Holy Church's Ten Great Saints as well as a Japanese otherworlder. She is second only to the Holy Emperor in authority within the Church.

Hinata has short black hair and violet eyes. She often sweeps her bangs over her right eye while tucking the left side behind her ear. Her eyes are described as cold and calculating, as though they are always looking for the solution to some kind of mathematical proof. In terms of appearances, Rimuru described her as "stunningly beautiful."

She usually wears the Holy Knights armor, which is an armor with a white coat draped over it, as well as a monocle. She carries a powerful Legend-grade rapier known as Moonlight on her hip, gifted to her by Luminous personally.

For causal wear, she wears a sleeveless minidress.

Hinata is a cold pragmatist who doesn't shy away from cooperating with anyone as long as it benefits mankind as a whole, even cooperating willingly with Demon Lords even though the Western Holy Church believes in killing all monsters. She is willing to give anyone who asks her advice, but if that advice is ignored then she won't bother repeating herself. She is also extremely stubborn, always refusing to compromise with others, and will not listen to reason unless ordered to by Luminous. She does not like being made fun of, as she angrily glared at four of the Saints when they mocked her sensitive tongue.

Within the Church, she is an extremely harsh but powerful and efficient leader, who singlehandedly reformed the Crusaders into a much more efficient and streamlined version of itself within two years of her rise to power. She also established the Ten Great Saints, a group of formidable knights that stood against the Ten Great Demon Lords in public view.

Hinata holds Shizu in high regards, due to her being the one who trained her and showed her what genuine kindness was for the first time.
