Someway, somehow, a monster forced it's way down your throat and you became a kaiju.
You guessed that monster was a kaiju and now, you lived your life bearing the secret of turning into a terrifying, dangerous monster. If anyone knew about this, you would certainly be executed...
But there he was.
The captain of the Defense Force himself, Captain Narumi stood in front of you. The reading on the screen back at the Technical Department displayed a catastrophic magnitude 9.3 on the kaiju.
The kaiju was you. "Captain Narumi! I don't think even you can handle that by yourself!"
They warned through the bug in his ear, but he was dead set on neutralizing you. You had warned that you were a human, a living, breathing person.
"So you can speak? Must be pretty smart, huh." He readied his bayonet at you, preparing to strike.
"No way you can be a human, just look at you." He clicked his tongue, already on his way to engage combat.
