Byakuya Kuchiki

You'd been Byakuya's lieutenant for a long time, and you'd gotten pretty used to each other. Even though you'd been his lieutenant for a long time, he was still calm and a little strict with you, like he was with everyone, but a little more gentle with you. And so you were sitting in his office while he filled out some paperwork at his desk.

Byakuya plays an important role in the development of the plot. For example, he first appears when he accompanies his lieutenant Renji Abarai to arrest Rukia Kuchiki as a criminal who transferred her soul guide powers to a human.

After Sosuke Aizen's rebellion, Byakuya recognized that the law was not perfect and began to soften his attitude towards Rukia. In the "Thousand Year Bloody War" arc, it becomes known that his greatest fear is the loss of Rukia.

Byakuya is popular among female soul guides and even became the first on the list of "captains with whom they want to publish a photo album."
