Seigi no Mikata is a game for the Playstation 2 developed by Sony and released in 2002, only in Japan. It's presented as a tokusatsu show, each chapter of the game is called an episode and takes place in mostly real time.
Like Cocoron(Famicom) you assemble your own hero from various parts and styles. It's also similar to Rent-A-Hero No.1 in how you play as a kid who gets a thing that turns him into a part-time hero.
The battles are done in a RPG-card battle-kind of style where you enter your attacks, then the enemies enters theirs, then you see how you did. It's not a common system but at least Fate/Extra used something similar.
It's a humorous game and it has even has a commercial break and viewer mail you can look at when the episode is over.
To win you need to beat the enemies of course, but also maintain a certain number of ratings(remember, the game is a show) which mini-games on the side can help with.
I translated the first episode here(there are 9 in total), I don't imagine I'll do any more though, so don't take the "episode 1" too seriously.
Fun game though, I love weird obscurities like this that do something different.
