D contract.
On that day that only comes once in a lifetime, by calling D's full name and offering his blood, this contract can be concluded.
Sell your soul and body for two years in exchange for a wish that is close to omnipotence. Even if you want to become the king of a country, it is only a matter of words.
Everything is fate.
But fate can give you the opportunity to seize your own destiny.
If it were you, would you choose to sign this D contract with Devil?
