A refreshing, super-talented prodigy who does not reach his wits' end with matters. While David views God first and foremost over all other things, on the other hand, he is a thorough realist. Placing his duty as an agent of God first and foremost, David possesses the strength of will to maintain an extreme calmness in the face of utter desperation, clear-mindedly evaluating his situation in a realistic manner. He does not consider his summoning as a resurrection of himself, but namely a summoning of a person that possesses the spirit of David himself; however, he does not openly feel a sense of inferiority in existing as such. There is no difference in being a messenger of God in both the present time and during his own lifetime for he holds a view of being pleasant to merely feel the grace of God no matter what kind of person he is. On the occasion of being summoned as a Heroic Spirit, he will wield his power to the maximum degree without accidentally holding back. Furthermore, bringing alongside his body is the knowledge he absorbed in greed related to the advancement of technology and human history from the time after his death to the arrival of the present time.
