Horimiya, Vol. 13

In the thirteenth volume of the Horimiya manga series, the focus shifts from the central couple of Kyouko Hori and Izumi Miyamura to highlight their classmate Shu Iura. At school, Iura is known for his loud, energetic, and sometimes irritating personality. However, a deeper look into his home life in contemporary Japan reveals an entirely different side of him: a strict, protective, and caring older brother to his younger sister. As his group of high school friends begins to catch glimpses of this unexpected domestic persona, they must navigate the surprising contrast between the boy they know in the classroom and the dedicated sibling he is at home.
