These two were the most different from each other. Koda is a caveman new to our world and speaks awkwardly. Nobuharo is from modern times and a mechanic. Both are well-meaning and sweet. He has a penchant for doing oyaji gags, outdated and unfunny puns which his late brother-in-law enjoyed, and which Canderrilla earnestly finds amusing, but usually makes everyone else who hears them groan.

Tessai did not appear until after Gold joins the team, he is a focused martial artist from 6th century China who regards himself as an embodiment of the yingyang concept while causing him to be remarkably hard-headed.
