How members call him: Hayato, Jinto -> "Daichi" Shunta, Jyutaro -> "Dai-chan"

He's a tsundere and a bit cynical. He is highly regarded for his exceptional singing and dancing skills. However, his own self-esteem is low, and he tends to disparage himself. He is good at studying but not very good at sports. Among close friends, he surprisingly laughs a lot and has a loud laugh. His general demeanor is soft.
