David Kruegel
Known as Tekkaman Sommer or Tekkaman Summer. A survivor of the fictional Black September incident (a massacre in Prague), his easygoing, joke-telling mannerisms conceal his true feelings - deeply troubled by the past and often depressed, he goes bar hopping in an attempt to drown his sorrows, compounded no doubt by his love for Aki, who he knows is already beyond his reach. He unknowingly befriends Dead End by virtue of being one of the few survivors of Black September, and the only person Dead has met capable of truly relating to his loss.
