The Altered Puzzle The Promised Neverland X Male OC

There are two species
Demons and humans,
Demons are the top of the food chain aren't they?

No,
The top are devils, yes devils. These devils aren't demons, No they are not. They are stronger, more stronger and they have a human appearance, they eat humans like demons, but the amount of power they have is terrifying
But they were wiped out, weren't they?
The answer is yes
So it makes no sense why one remains
And a hybrid might I add
Yes a hybrid. A human and devil

Because of this, it is the strongest and most dangerous being to walk the earth

Sakura.
Cherry blossom. A weird name for a boy isn't it
An 11 year old, in the Grace field orphanage is in fact the strongest being. His heritage is unknown but everyone fears him.
Except the kids of course, for they do not know anything about him, and he will like to keep it that way

But not all secrets can be kept forever. Will they find out?
If they do how will they react?
All you need to know his never make him angry
