Seasons & Episode
Ramune is visited by Kengo, a young man whose penis has turned into a chikuwa fish cake. Though there must be some reason for it, Kengo refuses to talk. When Kengo begs Ramune to fix it, even if it's only temporary, Ramune hands him a certain mysterious item. Kengo accepts the item and begins talking to a woman named Yui about going on a date, but...
Ramune uses his Shoji Vision to invite Kuro to a mysterious item shop. Kuro discovers the mysterious item shop Akatsuki at his destination. At first glance, the store appears to be a candy shop, but mysterious items are sold in the back. Kuro meets shopkeeper Nico and his great-grandmother and former shopkeeper Ayame, a girl who remembers her past lives, and is watching her make mysterious items with great interest when a strange man appears.
Takaharu, a high school student whose fingertips have turned into chili peppers, comes to see Ramune. He seems to have some idea as to why he's haunted by the mysterious. The mysterious nail clippers Ramune lends to him can be removed from their bag once Takaharu stops hiding his true self. Initially Takaharu can't even untie the drawstring, but...
Kuro's classmate Aona is troubled by the popcorn that keeps popping out of his head. Aona says it makes him sad when the popcorn disappears, so Ramune lends him a bag that can be used to store the popcorn. Why is Aona's head producing popcorn, and why does he feel sad when it disappears? Ramune tells Aona that the treatment method will become clear if he asks himself those questions...
Aona's head began producing popcorn because his father prohibited him from making the creations he loved. Concerned for Aona's wellbeing, Kuro heads to the hospital where Aona's mother is staying in order to seek her help. However, Aona ties balloons to the bag that's now full of popcorn and releases it into the sky. Kuro and Ramune rush out of the hospital in order to recover the bag.
When he was young, Kuro could see things that ordinary people couldn't. After being taken to the hospital, he pretends that he can't see anything so that his family won't worry about him. However, the things remain visible even after years pass. Furthermore, Kuro begins coughing up sand and can no longer eat. Desperately clutching at straws, he visits a certain place...
So long as people have hearts, there will be those with worries and concerns. Those hearts are then invaded by something strange, causing them to show strange physical symptoms. These ailments, called "mysterious diseases", exist unseen to most people. Modern medicine offers no cure, but there is one doctor who fights these diseases along with his pupils. His name is Ramune. He looks nothing like a doctor, is foul-mouthed, and does whatever he pleases, but he has the ability to pinpoint the cause of the troubles hidden deep within his patients' hearts and cure their mysterious diseases.
