While most ordinary humans utilize only 30% of their brains, a group called the "Dokeshi" can access 50 to 60%, granting them special abilities. However, these powers come with a price: the Dokeshi must adhere to specific restrictions. Violating these rules can result in the loss of something precious from within. In young Shotaro's case, he is required to perform one good deed every day! In the central town of Toykyo, he meets a girl named Mana, and together they embark on a journey to find Shotaro's childhood friend, Emine. Will Shotaro manage to do good daily, or will he succumb to laziness on his journey?
