Hatabō is a Champion of Justice-dajou!

An upcoming election between Dayon and Iyami looks like it's over before it's even begun, with Iyami hiring hitman Joe Hatabou to take out his rival. However, when Iyami becomes President-Elect, Joe enacts a "Golgo 13"-style revenge on his soon-to-be administration and a hired mob.
