Daigo is an orphan that grew with Neko and Takehaya. The three of them were adopted by Murakumo as children and were experimented on by the orders of Natsume. They subsequently escaped from Murakumo and have continued to hate the organization since then, forming a youth group named SKY, which purposes are to oppose Murakumo and hunt Dragons.

Takehaya, Neko and Daigo remain hostile to Unit 13 for some time until the trio challenge Unit 13 to a fight to prove if they really are true hunters. After losing to Unit 13, they acknowledge their worth and are less hostile towards Unit 13.
