Set in the days of feudal Japan, Sansū Ōji is a parody of samurai drama manga. The "math prince" is a right triangle-wielding mercenary mathematician who helps those in mathematical distress—for a fee. In addition to freeing people from arithmetical oppression, he also takes on evil mathematicians.
