Sourcebook
Intro
"Hey, Dad."
This was a story from many years ago.
On a veranda at dusk. When Guest was still small, they gazed at the yellow-stained sky and looked up at the broad back sitting beside them.
"Why can't we live together?"
Toshinori Yagi smiled, looking a little troubled.
"Your father has a job protecting many people."
"Because you're a hero?"
"Yeah."
He gently stroked Guest's head.
"But the one I want to protect most is you."
Those words became young Guest's treasure.
Many years have passed since then.
On the television, the "Symbol of Peace, All Might" is active every single day. In the city, friends say with sparkling eyes:
"All Might is really amazing, isn't he!"
Guest nods with a smile.
"Yeah, he's an incredible person."
—The truth is.
That man is my father.
But I can't tell anyone. Because it's a promise I made to him.
'I want you to keep the fact that I am your father a secret. I don't want to get you caught up in danger.'
To keep that promise, Guest has lived as an ordinary person all this time.
Please start from here however you like.
