Shin Musegi (DxD: Nocturne)

"You were so weak, I got bored... In other words, you weren't worth killing at all."

- Shin Musegi Shin Musegi, also known by the names of the Demi-fiend and the Hitoshura, is the protagonist of the game, "Shin Megami Tensei III: Nocturne," as well as the fanfiction story, "DxD: Nocturne." A human that was turned into a demon after the events of the Conception, he forfeited his human heart in order to obtain the strength necessary to ending the cycle created by the Great Will.

He is being both feared and awed by many individuals, primarily by the Old Satan Faction, who desperately desire him to their side. He is well respected by his own companions, especially by the Fiends, who recognize him as the demon who stands above all others. The mysterious old gentleman in the wheelchair refers to him as the one who will end the struggle between the light and the darkness, once and for all.

His main theme is "Flashback," performed by Akiakane. According to the author of the story, the song refers to his hidden desire to return to the old days.

Design
Shin is a relatively young individual in his late teens, bearing short black hair and gray eyes. When assuming his true form, his eyes turn crimson, signs of him having lost his humanity entirely. While under the guise of a human, Shin is dressed in various outfits, such as the Kuoh Academy uniform, and his own personal attire, such as a pair of slim short and a leather jacket with purple and white strips.

His true form retains his human appearance, but reveals it's true features: glowing green tattoos that turn red when angered, albeit rare occasions, and a horn on the nape of his neck.

Personality
Shin is generally a laid-back and composed individual, nothing really fazes him, having fought in the Vortex World for so long. He comes off as an introverted person, but does try to mingle with others when it is required of him. Despite being a true denizen of darkness after losing his human heart, he still retains concepts such as compassion, kindness, and other beliefs and longings. He also feels somewhat sad that his world has all but vanished, despite the fact that it was erased by the Conception.

As the story progresses, Shin's character is further flushed out, and parts of his past are revealed. In the past, when he a demon "with the heart of a human," he was a nervous, if not paranoid person, constantly weary of his surroundings, having fought in so many battles, but shows genuine relief when he finds his friends, alive and well. He also expresses a great desire to return his world back to it's original shape, in contrast to others' desires for a new world order, which the blonde child refers to as the "path of thorns." He was also a compassionate, gentle young man who disliked killing, but his demonic nature found it hard to repress the bloodlust that attracted many demons to him. To his comrades, Pixie especially, he is charming, charismatic, and a man who will do anything to protect what is important to him.

At the end of his journey in the Vortex World, however, Shin has lost his human heart, and therefore, only has a 'semblance' of the man he once was. Despite this, the demons he has encountered remark that he is still the same demon they have aligned themselves with, and continue to follow him. He has, however, developed a longing for a true battle, such as his fight with Kagutsuchi. Being someone without an equal, he becomes bored with fights that have no relative interest to him. When he does, he shows a slight, maniac grin, and starts to become more serious. Against those who have angered him, or he sees as individuals who are even worse than demons themselves, he shows a brutal, merciless side that is most fitting of a demon.

According to many characters who knew the DxD world's Lucifer, Shin greatly resembles him in many aspects, and as a result, many members of the Grigori, as well as a few angels, have taken to calling him the Second Coming of the Fallen Angel.
