Fureru

Aki Onoda, Ryō Sobue, and Yūta Inohara, are childhood friends attending the elementary school. Aki investigates the Shinto shrine in the island cave, meets a yellow tailed hedgehog Fureru, and adopts it as a pet. When the boys touch each other and hear their inner voices, they are caught by Fureru's magical power within the fur. In the aftermath, they cannot hear their inner voices in isolation when touching each other.

Ten years later, the trio move to Takadanobaba in Shinjuku, and become house renting tenants on a leasehold estate. Fureru stays at home, Aki becomes a chef and bartender, Ryō becomes a real estate agent, and Yūta studies at the fashion university. That night, Fureru knocks a thief off the bridge, after Aki retrieves a stolen purse and returns it to the owner Nana Asakawa. The trio invites Nana and her bodyguard Juri Kamozawa to stay at the house. When Aki, Ryō, and Yūta invite Juri and Nana at the bar, they break up with each other. The night before being ambushed and wounded while alone, Nana identifies a real stalker as the school's assistant teacher, Kohei Shimada. While Nana recovers, Juri tells the trio that Kohei has been eavesdropping Juri and Nana at the same time he is impersonating a teacher. After leaving the hospital and returning home, the trio are visited by their folklore teacher Wakita. He narrates the story about Fureru in the island with fertile soil: it connects the mind to people during ancient times. The villagers struggle to cheat over resources, but found Fureru in the cave. It helps everyone unite and oppose minds which can be removed before thoughts can convey with hearts. Aki, Ryō, and Yūta stack their hands, but they still cannot hear and sense their voices.

The next day, Aki, Ryō, and Yūta argue, suffer mental breakdown, and prepare to move on. However, Fureru becomes frightened and trapped them in the parallel world. They manage to escape from there by overcoming negative emotions and reconciling with each other. Back in the real world, the trio discovers magical threads driving everyone mad in town. As they follow it to the stadium, Aki comforts Fureru, by climbing up to the tower and zip lining the threads that he had connected on his finger. Fureru transforms into a white living ball and the threads vanish from the town, reverting the minds of people into an original state. After the police arrest Kohei, Aki, Ryō, Yūta, Juri, and Nana, reconcile and remain friends. Aki and Fureru part ways from Ryō and Yūta, after leaving the house for an expired lease.
