Demi-fiend Husbando

The protagonist of Shin Megami Tensei III: Nocturne, soon to become the Demi-fiend, is one of Ms. Takao's students who survives the Conception and is reborn as a demon. Following the tradition of Shin Megami Tensei series, the Demi-fiend is a silent protagonist, where his personality is based upon players' actions and decisions. As per the franchise's standards, he is a blank slate at the very beginning of the game, unsure of the role he is to play in the world that is to come; creator or destroyer, master or servant. This is seen when Kagutsuchi scans his heart at the moment of the Conception. The divine being finds nothing there, no defined ideas or motives, and decides he needs to find his own ideology and Reason in the Vortex World. During the game, his personality develops further depending on the choices of the player, molding him into a follower of three Reasons or a person who rejects all of them, either through weakness, a true desire to see the world reborn, or an honest wish to end the eternal cycle of death and rebirth. The definitive moment is when Kagutsuchi, at the entrance of the Tower of Kagutsuchi, again scans his heart and determines what lies within. He is, however, constantly defined by his choice to act; it is impossible for him to remain idle while others move behind his back. At least initially, he is a relatively trusting and naive person; this is a trait Jyoji Hijiri uses and abuses to convince him to be his errand boy in the Vortex World to the point of sending him to deactivate the Nightmare System and confront both the Assembly of Nihilo and the Mantra Army. Isamu Nitta remarks upon said trait in an insulting fashion upon being released from Kabukicho Prison as well. Isamu would later expand upon this and note how it could very easily be turned into a flaw. This trait also makes him a relatively predictable power, provided he can be forced into a situation where someone can directly profit from his intervention (as seen when Isamu captured Hijiri and forced the Demi-fiend to destroy the Amala Temple demons to see him again). Among those who help shape the Demi-fiend's personality is Aradia, who confronts him openly about how much he was willing to sacrifice everything in pursuit of the world and forced him to either confront his fears or admit them. Others include: Gozu-Tennoh, who inquires about his lust for power; Lucifer and the Fiends, who stand poised to create a new demon of Chaos; Metatron, who seeks to avert Lucifer's goal; Sakahagi, who confronts him with his demonic nature; Futomimi, who embodies a more rational and human side; Hikawa, who offers the temptation of a world ruled by serenity and free from pain; and Yuko Takao, who represents the last thin strands of the person he used to be. He is also desperate for reliable information about the Vortex World and how to manipulate it (desperate enough to be swayed by Lucifer, following his orders regarding the Candelabra): Beelzebub notes when fought in the Fourth Kalpa of the Labyrinth of Amala that he was following Lucifer's plan without having any clear idea of what exactly it entailed, getting snippets of information from enemy and ally alike, lightly mocking him for such an irrational stratagem. Due to different choices in the course of the game, his personality can be developed further, revealing character flaws and strengths, changing others' viewpoints of him and affecting the possible ending. In his brief appearance in the Shin Megami Tensei IV Apocalypse DLC, the Demi-fiend is gruff, imposing, and short on patience, as well as having a lust for battle to a certain degree, evident by his desire for a rematch with Lucifer.
