The Beautiful Patissier, Yumichika!.Twelfth division Soul Reaper Rin Tsubokura is sent to Karakura Town to conduct research, and Hanatarō Yamada accompanies him as an escort. Yumichika Ayasegawa, one of the Soul Reapers based in the real world, is assigned as their guide. While Rin searches for sweets to purchase, they encounter the ghost of a chef who wants the three Soul Reapers to bake a cake for his mother. Upon delivering the cake, however, the chef's mother refuses to eat it because it reminds her of her son, causing the chef to begin transforming into a hollow. Attracted by the chef's transformation, a Menos Grande arrives, and Hanatarō is able to both stop the chef's transformation and defeat the Menos Grande with the shikai of his zanpakutō. Using a device, Rin makes the chef visible to his mother, and he convinces her to eat the cake.
