Tatsuya Granger

Tatsuya is Takao and Hitoshi's father. He is an archeologist. His job allows him to travel aroundthe world, yet it also keeps him from spending time with Takao. For a few years, Hitoshi accompanied Tatsuya on his trips.

He only made a short appearance at the end of the first season. He gave his views on Volkov and Souichirou's real motives and shared his knowledge on the Holy Beasts.

The name Tatsuya means "become dragon" and it was most probably chosen to relate to Takao and his Dragoon.
