I read about Dragons in the Wiki but they are truly immortal in terms of lifespan unless they are killed in battle against somebody but they outlive every race listed here. The lifespan of a Devil is not infinite because they are long-lived but they die after a certain time but Dragons have no limit unless they are killed in battle against somebody so in terms in what you classify Dragons they are true Immortals.
