Yamato Nikaido (二階堂 大和, Nikaidou Yamato ) comes across as very lazy and easy-going, but he is very passionate about what he does and cares a lot about the other members of IDOLiSH7. He took up the position of “Leader” only because he was the oldest in the group, he actually considered pulling himself out of the audition for IDOLiSH7.

Yamato has held a very deep dislike towards the entertainment world in general before joining the agency, And it's implied that he was connected to it himself at some point in the past. Now after he's joined IDOLiSH7, he genuinely enjoys being an idol and cares for the other members of the group.

He can’t actually see much at all without his glasses, is a confrontational drunk, calls himself oniisan (big brother), is weak to honest and hardworking individuals like Riku and Mitsuki, and owns a personal cleaning robot named Musashi.
