He is a classical literature teacher at Sakuragaoka High School. He has taught there for a long time, since he was the supervisor of the Light Music Club when the members of the band Death Devil ([Norimi Kawaguchi](https://anilist.co/character/33872/Norimi-Kawaguchi), [Sawako Yamanaka](https://anilist.co/character/19569/Sawako-Yamanaka), Jane and Della) still attended school. Since the band members were too wild in Horigome's eyes, they caused him many problems, forcing him to scold them over and over again.

In the movie, Horigome caught wind of Ho-kago Tea Time's illegal concert and rushed towards it, despite [Sawako](https://anilist.co/character/19569/Sawako-Yamanaka)'s efforts to delay him. After he managed to reach the classroom, it was revealed that he just wanted to see it with his own eyes, having no ill intentions at all. Horigome told [Sawako](https://anilist.co/character/19569/Sawako-Yamanaka) that the Light Music Club had changed greatly, having become much "cuter". The class then pulled him and [Sawako](https://anilist.co/character/19569/Sawako-Yamanaka) inside, making Horigome smile.

It is the new year, which means that the senior members of the Light Music Club are now third-years, with Azusa Nakano being the only second-year. The seniors soon realize that Azusa will be the only member left once they graduate and decide to recruit new members. Despite trying many methods of attracting underclassmen—handing out fliers, bringing people into the clubroom, and performing at the welcoming ceremony—there are no signs of anyone that plans to join.
 
While heading to the clubroom, Azusa overhears Yui Hirasawa say that the club is fine with only five people and that they can do many fun things together. Changing her mind, she decides that they do not need to recruit any members for the time being.
 
K-On!! revolves around the members of the Light Music Club as they experience their daily high school life. From rehearsing for concerts to just messing around, they are ready to make their last year together an exciting one!
