Most normal humans only use 30% of their brains, but a group of people known as “Dokeshi“ can use 50 to 60% of their brains, and thus have special abilities. These powers, however, come with a price: the Dokeshi must observe certain restrictions. Ignoring these rules can lead to the loss of something precious from within. In young Shotaro’s case, he has to stick to doing a good deed every day! In the central town of Tokyo, he meets a girl named Mana, and together they go on a journey to find Shotaro’s childhood friend Emine. Will Shotaro be able to do good daily or will he succumb to laziness on his journey?
