The reliable older brother figure of FRAME who wishes for peace and smiles!

Seiji Shingen is one of the Idols available to produce at 315 Productions. He was a former member of the Self-Defense Forces before forming the Idol Unit FRAME with Ryu Kimura and Hideo Akuno.

Profile[edit | edit source | hide | hide all]

Seiji is a former Self-Defense Force member. Due to an injury, he has retired from the military and become an idol. He has a big-hearted personality but is rather boorish and weak when it comes to dealing with women. Contrary to his appearance, he has another side to him, one that loves precision work and domestic chores. Seiji always dotes upon his niece. Perhaps the reason he became an idol was to make her happy¹.

Resume[edit | edit source | hide]

Reasons for Becoming an Idol
Because it's a job making people smile.
Personal Motto
When you smile, the world smiles with you.
Comments for the Future
For the time being, I’d like to try out different kinds of idol jobs. I’m not really sure what sort of job I’m suited for, but... Ah, well, I’ll get by one way or another.
Comments about Unit Members
Hideo is often misunderstood, but he’s a nice guy with a strong sense of justice. Ryu gets the job done when he has to. He’s a man who deserves my trust. I think it’s truly fortunate we were able form a team together.
