Yasochika Iemura

He is dissatisfied with being treated as inferior by other squad members, as his actual status is lower than the third seats of other squads. In the anime ending "Houki Boshi" 4th Squad version, he is seen scolding the 11th Squad members who came to visit and drink in the hospital room, and someone from the 11th Squad throws a sake cup at his face.

Although usually serious, his speech becomes intense when his emotions are heightened.

By the time of the final arc, the Thousand-Year Blood War, Hanataro Yamada has been promoted to the third seat. It was revealed during the second invasion, and since Iemura himself survived the first invasion, it wasn't a vacant position. It is assumed that either both of them held the third seat like the 13th Squad in the past, or Iemura had been transferred to the 7th Squad by that time.

After the decisive battle with the Sternritter, during a major personnel reshuffle due to vacancies in captain-level positions, he was transferred from the 4th Squad to become the vice-captain of the 7th Squad, which was revealed in a novel. This included the role of healing injuries from Tetsuzaemon Iba's self-training.

However, in the sequel "Jigoku Hen" published in 2021, it was revealed that a person named Yuu Rindou had taken the position of vice-captain of the 7th Squad.

Iemura's whereabouts remained unknown for a long time, but in an official Q&A released in 2023, about two years after the aforementioned "Jigoku Hen," his current situation was revealed.

According to it, Iemura voluntarily stepped down from the vice-captain position, yielding it to the more capable Rindou, and was demoted to the third seat. Despite stepping down on his own, Iemura was depressed, and Hanataro, seeing this, invited him back to the 4th Squad, where he eventually returned.
