Mr Saenai is a tired middle aged salaryman. While his lazy wife Enko dominates him at home, his subordinates look him down at his workplace. He is a man of avoiding take responsibility and everyone knows it.
One day he encountered a strange old man. Bluish suit in his hands, the old man asked Saenai if he want to be a superman. Saenai thought of the old man doesn’t have normal frame of mind so he walked away. But wherever he goes the old man was there. Saenai was surprised and was startled when the old man flying into the sky.
As the old man appeared again, Saenai was in the midst of trouble caused by Enko’s unreasonable request. Without any consideration of husband’s business priority, she ordered him to deliver the lunch box to their daughter Haneko. By borrowing the superman’s suit, Saenai could fly in the air and somehow cope with the request and got back to office just in time.
Since then, mysterious things happen to him.
Voice of people who call for help sounded in his ears no matter how far the ones are.
He flied to them to solve the trouble one to the other and came to know that the suit has really super power beyond human limitation. In addition, due to the “forgetting beam”, the memory of superman was totally deleted from those who saw Saenai with super suits.
Having a struggle in his mind, Saenai’s life as superman began.
