Yoshimori as a cake lover is obsessed with the legendary chocolate cake, mentioned by his father Shuji Sumimura, that will be secretly offered early every morning to a limited number of people at a bakery. Yoshimori sends an elegant cloned shikigami in order to hold his place in line, but he loses focus at night when fighting an ayakashi called a fire mole, while the shikigami simultaneously deals with a group of thugs. Tokine reluctantly calls Yoshimori the next day for help to kill a cockroach, to which he finally manages to do so after Tokine accidentally pushes him on the ground, thereby smashing it. Yoshimori then discovers that Shigemori ate his share of the legendary chocolate cake much to his dismay. Afterwards, Tokine continuously avoids him, but eventually gives a new shirt and a piece of the legendary chocolate cake as gifts.
