Royal Lethality

The Book

...

"We'll check the book..."
AFO said as he stood up.
He walked over to his shelf and pulled out a pen case.
Inside was a pen.
However, behind that pen was a very special key.
AFO meant to give it better hiding spot but he didn't have time nor did he feel like hiding it somewhere he could forget.

The key was quite pretty, it was a gold and silver mix with blue and black Jem's encrusting it all around.

"Follow me"
AFO said as he headed towards the door.

Dabi quickly ran off and hid, he was almost spotted.
He watched them walk out and head for the stairwell.
Dabi, having been specifically trained to spy well, followed behind.

He watched them go to the very bottom floor and enter what seemed to be an old library.
They then went to the back corner of the room and pulled a book.
The shelf moved.

Dabi stared in awe as a door was revealed, it needed a key.
And so, AFO inserted the key he had in hand.

The door opened up, revealing a small dimly lit room.
Inside the room was a Book incased in glass.

The book was titled "The Wielders"

It was a large book the size of a table.

AFO flipped through the pages, he knew his name would be on the page.
The book would inscribe the wielders of the sword as soon as the sword picked an owner.
They were connected and as long as the sword wasn't destroyed the book would remain endless.

Tomura and AFO both lightly gasped when they noticed right after AFO's name was...

"Izuku Midoriya"

Written and underlined, signifying he was truly the new and current owner.

"...well...
This isn't good"
AFO muttered as he shut the book in disbelief.

Dabi gasped, this information was good.

"Father...

Doesn't this mean I get the throne now?"

"What do you mean?"

"You told me just a few weeks back that if the sword had truly picked that brat as it's owner that I'd get to inherit the throne.
You sealed a deal on it too"

"...I did say that...

Well Tomura.
You do know that you need the sword to properly inherit the throne completely, right?

And that's why this book is usually brought out during coronation ceremonies?"

"Wait....
Does that mean that brat has the right to the throne!?"
Tomura screamed in a fit.

"No, of course not. He isn't even of the bloodline.
The sword picks out owners based on strength.

Which is odd...
His quirk is only telekinesis which isn't stronger than my quirk, so how come the sword chose him?

...

His quirk must be more than what it seems.

Tomura, your right to the throne hasn't been removed.
Our issue at hand is retrieving the sword.

Well we know he isn't in the Empire
...
And he isn't in the kingdom...

That doesn't leave many options, he could only be in the forest of the beasts...

Or another empire entirely considering he can fly..."
AFO began to mutter, only stressing Tomura out.

"What do we do???"
Tomura asked as he snapped his father out of it.
