Most humans use only a small percentage of their brainpower, but a certain group of people called "dokeshi" can use a greater percentage of their brain to unleash special powers, given one condition... For dokeshi Shotaro, that condition is doing one good deed a day. In exchange, he has the ability to use the powers of any animal by biting its bones.
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?
