Michishio Nagasumi waited. The lights above him blinked and sparked out of the air. There were mermaids in the school. He didn't see them, but had expected them now for years. His warnings to Seto San were not listenend to and now it was too late. Far too late for now, anyway.
Nagasumi was a student for fourteen years. When he was young he watched the water and he said to dad "I want to swim in the water daddy."
Dad said "No! You will BE KILL BY MERMAIDS"
There was a time when he believed him. Then as he got oldered he stopped. But now in the school of Saitama he knew there were demons.
"This is San" the radio crackered. "You must fight the mermaids!"
So Nagasumi gotted his manly mode and blew up the wall.
"HE GOING TO KILL US" said the mermaids
"I will shoot at him" said Yoshio and he fired the bullets. Nagasumi punched at him and tried to beat him up. But then the ceiling fell and they were trapped and not able to kill.
"No! I must kill the mermaids" he shouted
The radio said "No, Nagasumi. You are the mermaids"
And then Nagasumi was a fish.
