The Life That Can't Be Forgiven (許されざるいのち Yurusarezaru Inochi) is the 34th episode of Return of Ultraman.


Go reunites with his old classmate Mizuno at Sakata’s factory. While Jiro delivers an experimental tool asked by Mizuno, Jiro was told that he is mutating a new life form synthesized from animal and plant. That night, the experiment succeeded and a new life form named Leogon was born. However, Leogon soon turned into a giant monster and escaped the laboratory...

  • Return of Ultraman Volume 9 features episodes 33-36.


  • This episode was notable because it was written by then 16-year old Shinichiro Kobayashi, who later wrote a similar story that became the basis for Godzilla vs. Biollante, upon his story winning First Place in Toho's Godzilla Story Finals Contest (a big fan event at the time).
  • In the climax, the song "Flower, Sun, Rain" by famed Japanese rock band PYG, underscores the action and finale.
