Demon Slayer: Kimetsu Academy manga volume 4 features story and art by Natsuki Hokami.

It might be winter, but things at Kimetsu Academy show no signs of cooling off! If Giyu wants to enjoy some warm, freshly baked bread, he's going to have to overcome his embarrassment about his stern teaching style and set foot inside the Kamado Bakery. Then a broken vase somehow results in a death-defying adventure inside Ubayashiki Manor. There's also the washing of gym clothes, crane games, inappropriate train rides, and more!
