Gertz

A survivor from the Village of Miracles who escaped after his body was experimented on by Amiba (who was posing as Toki at the time) and given three days to live. Fearing for his life, Gertz went insane and caused a commotion fighting Haystack in front of Ellery's shop until Kenshiro intervened. After calming down, he told Ken of the Village of Miracles and Toki's apparent corruption and his condition, but was killed by the effect of the vital point before he could be saved.
