Team leader of MMR's Yellow Gears and Robo Master of Drill Robo, Daichi is a young boy with a high spatial awareness ability which allows him to estimate the dimensions and or the distance of objects just by looking at them, his ability also allows him to know when an object falls (as seen in episode 4).

He is usually quite shy and sometimes has the habit of having a sore stomach before anything big happens like a rescue or a public event.

At the beginning of the anime, Daichi doubted his abilities as a member of MRR and wanted to quit but one rescue made him realized his potential, eventually Daichi made up his mind and decided to stay in the end.
