Yukio Oikawa

Yukio Oikawa is a character in the anime series Digimon Adventure Zero-Two considered by many to be the most tragic character in the series. He was one of the few human adults to have a knowledge of the Digital World, wanting above all else to go there.

After the death of his best friend Hiroki, he became possessed and deceived by the evil Myotismon and helped unwillingly facilitate his revival. He was drained of most of his life when Myotismon separated from, memorably using the power of the 'other world' to bind what remained of his lifeforce to the very world he loved, restoring it to the way it was.
