The temperature is at an all time high and Kagura's Yato DNA kicks in while the Yorozuya are on another job. Due to the heatwave, Gin and Shinpachi join Kagura under her parasol and eventually kick her out, leaving her lying in the dust. However when they go to check on her, she is not responsive. Gin and Shinpachi then take her to the Oedo Hospital for treatment, but due to lack of information on the Yato, the doctors are unable to do much. In order to get Gin and Shinpachi to regret what they did, Kagura goes through the trouble to fake a worse illness than she actually has.
