TV series
Hiroto Miyama is an unconventional young lawyer who dances to his own tune and gets a little obsessive. For one thing, he’s only interested in criminal cases, and he will never give up in his pursuit of the truth even if offers only a 0.1% chance of being discovered. Japan’s 99.9% criminal case conviction rate leads the world, attesting to a “highly reliable” judicial system. In other words, once a crime suspect is indicted, prosecutor arguments tend to be accepted hook, line and sinker. In the face of those 99.9% odds, there’s no money in being a defense lawyer specializing in criminal cases, but for Miyama, that’s where the interest and kernels of truth lie. From unexpected places, the mold-breaking Miyama stakes his reputation on a prayer of a chance as he clashes with hotshot lawyers who’ll go to any lengths to win in this gloriously fun, legal mystery.
