He is the grandson of the famous Bunraku master, Tachibana Zaemon. He is incredibly shy and lacks confidence in himself. However, when he is with his puppet, Ukon, he is able to focus himself and his crime-solving abilities. As a contrast to traditional Bunraku puppeteering, Sakon is an expert ventriloquist. He uses his talent of mimicing and throwing voices to confront the villains and often force a confession.
