That's Dagashi!.In the middle of the night, Tō is approached by Hotaru who asks for his help with something. Some days later, Kokonotsu realizes that Hotaru has not appeared at the shop at all recently and, after consulting with Saya, the two decide to pay a visit to the mansion where she is staying. Much to their surprise, they find a bedridden Hotaru who refuses to eat any kind of dagashi Kokonotsu brought with him as gifts for her and, after some inquiring, she reveals that her mouth ulcer had worsened. She wanted to get better in time to eat a new flavor of Baby Star Ramen that was about to be released. She also reveals that she decided to follow Tō's advice to stop eating dagashi at all to help her recuperation, but this triggers some withdrawal symptoms that lead her to attack Kokonotsu to claim the dagashi he brought. After calming her down, Kokonotsu and Saya discover that the "medicine" she was taking to treat her ulcer were bought at Kokonotsu's shop and were in fact, dagashi, thus not helping at all with her condition, much to their chagrin.
