Daigo Madoka

His name is Daigo (acted by Hiroshi Nagano, popular song singer). 23 years old in the story. Last name is Madoka. He was recruited for GUTS member by Mr.Sawai, Chief Officer of TPC, when Daigo was working with TPC transportation division.

And he is a key person of the stories and is able to transform to Ultraman Tiga. Usually he uses a torch called Sparkrence to transform, but sometimes even without it.

According to the holography of Yuzare which is working by artificial inteligent generated program and is supporting Daigo just like Yoda of Star Wars, Daigo has DNA of ancient super warriors called Ultraman around 30 million years ago.
