The official X (formerly Twitter) of Ichijinsha announced on Wednesday that Shiromanta's Senpai ga Uzai Kouhai no Hanashi (My Senpai Is Annoying) manga is ending with the 13th volume. The 12th volume (pictured above) is scheduled to be released on May 24.

Shiromanta originally began drawing the romantic comedy story as a web manga on their official X (formerly Twitter) and pixiv accounts in September 2017. Ichijinsha began serializing the manga under its Comic POOL web magazine in the same year and released the first volume the following March. The 11th volume went on sale in July 2023.

Seven Seas Entertainment licensed the manga for release in English in October 2019 and shipped the 11th volume on January 30.

Produced by Doga Kobo, a 12-episode anime adaptation began airing in Fall 2021. Funimation streamed the anime with English subtitles.

Synopsis
At a certain trading company, saleswoman Futaba Igarashi has managed to hold her respectable job for almost two years thanks to the guidance of her senior coworker—Harumi Takeda. However, due to Igarashi's short stature, Takeda often teases her and treats her like a kid, leaving Igarashi constantly annoyed by his antics.

Despite this, Igarashi notices Takeda's reliability as he is always ready to help whenever something at their workplace goes awry. As Igarashi and Takeda spend more time together, their relationship soon develops further than simply being coworkers at the office. [Written by MAL Rewrite]
