Sinopsis:

Most normal humans use only 30% of their brains, but a group of people known as the "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 one good deed every single day! In the central town of Toykyo, 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?
