Shingen’s ex-job was a Self-Defense Forces member. Though his past is rather vague, it's clear that he lost a close friend on the job and in his honor, he always wears his friend's dog tags in his casual attire. Shingen quits his job and became an idol in hope to make people smile and possibly have more of a cheerful lighthearted job compared to his old one. He is a bit sensitive whenever the topic is brought up and does not want anyone to worry about it, so he refrains from discussing it.
Shingen acts like a father figure to Hideo and Ryu. He cares a lot about their safety and goals and is always there to support them. He can be a bit shy, especially when it comes to romance. He acts very nervous around women and is more comfortable with men. But, he does have a young niece, Amane, who he is very passionate about. He treats her as if she was his daughter. Amane is known to have a crush on Ryu and hopes to become his bride, but of course, he is fully against it. Shingen’s signature trait is his strength and his size. He uses his strength to protect Hideo and Ryu. For example, he catches a falling beam during a performance but his size is occasionally an issue. He has a hard time fitting into his costumes, even when they're specially made. It’s to the point where Ryu and Hideo need to remind him not to work out as much or the Producer will get angry.
