The protagonist is not original, but his personality is very different from the original work, so everyone should just treat it as original.
He is a king, and his men have proven it since he was eight years old.

His fate was sealed when he awakened from the stone plate
He is the destined king, and no one can stop him, standing proudly in the sky.
Even if it is a god, it is the same.
