Heavy Sleeper – Jay is a god-tier sleeper, who is almost impossible to wake up whenever he falls asleep. Unless you try to feed him garlic. Then he wakes up, if only to curse the person who tried that on him.

The Immaculate Blade of Black Heavens – Suffering from the dreaded middle schooler syndrome, Jay's creativity, spontaneity, and self-delusion skills are really something to be feared. Indeed, he's capable of making up the stupidest shit on the fly, and his ability to be embarrassed is something that is utterly, totally non-existant.

Night Owl – Due to the fact that he's prone to falling asleep at random times, Jay never ever 'tries' to sleep. Instead, he's mastered the skill of staying up after his bedtime, generally doing things OTHER than studying. After all, studying is merely a demonstration of the oppression of the academic system, and he will not stand being a trained dog.

Word Weaving – Perhaps it's a side-effect of his delusional fantasies, but Jay is remarkably skilled when it comes to writing anything from essays to articles to self-inserting fantasy novels.

Mizuki Haruto was born a normal child to two mothers who birthed him via a semen donor. He had no defects, and was generally a rather healthy baby growing up. He liked to play with crayons and take naps, but that was the extent of his oddities as a child. Even at the age of five, there wasn't anything seemingly odd about him, other than the fact that he had a habit of dozing off often. After all, at that age, he was still a toddler. His parents rationalized that he was most likely just a person who needed lots of sleep to function well, and like that, he became the type of child who would simply lie down and sleep anywhere, from cradles to chairs to fields to sidewalks. It was only when he started to do the latter that his two parents decided that it was high-time that he paid a visit to the doctor.

After a few weeks, Haruto was diagnosed with narcolepsy, a neurological disorder that brought him into a constant state of sleep deprivation, as well as go into REM sleep almost instantly every time he takes one of those 'naps'. On the recommendation of the doctor, the Mizuki family thus enrolled him into Hamako Elementary, which had an elevator system that would lead into Middle School, and then, finally, bring him into Yamaku for his High School education. Over there, at least, Haruto would be able to get specialized help in regards to his odd sleeping habits, instead of all his classmates panicking when he collapses out on the sidewalk or something. Going through elementary school with little to no problems in regards to friendships and his studies, Haruto was a bright student, which was good, considering he missed most of his classes. Developing powerful self-study and researching skills at a young age to make up for missing lessons, he was recognized back then as the kid who always brought a small pillow with him everywhere, just in case he fell asleep then and there. A kid with two mothers who always wore his winter uniform and brought a pillow with him everywhere. That was what Haruto was in the elementary school.

It was in middle school that things began to change. Light novels were more popular amongst students, and like everyone else, Haruto became wrapped up with that form of media. He would spend his days in the library, often falling asleep while reading some book about a generic Japanese protagonist finding out that he had super powers and starts beating up demons. His trademark pillow was replaced with a book, and his dreams were becoming more and more fantasy-related. Vivid, lucid dreams of a fantasy world and constant sleeping slowly blurred the line between reality for Haruto, and after awhile, he wasn't quite sure which one was real. After all, all humans saw the world in a subjective manner. What proof did he have that his 'fantasy world' was merely a fantasy, and his middle school life was reality? That, combined with the twisted hormones of puberty, made him go through the male version of PMS for quite a long time. After all, he doesn't even know who his father is, and his whole family situation is odd. He's losing grasp on reality, and he doesn't even WANT to figure out which one was which. He's missed out on so many fun things in life due to his tendency to suddenly fall asleep, and now, he's regretting all of those things. It was ultimately a depressing part of his life.

Then, he met the catalyst who solved his problems with a single suggestion.

“What if they were both reality?”

What if he had simply lived in two separate realities, with the motion of 'sleeping' being the key to entering another dimension? What was wrong with simply having his consciousness and unconsciousness both be forms of a 'real life'? There...was nothing wrong with that, and through his catalyst, Haruto was introduced to the world of delusions.

By the time he came into Yamaku High, he was truly engrossed in his own subjective definition of reality, as Jay Lowell, the Thousandth Star.

Born of demonblood and the tears of angels, Jay was the fourth Demon of the Garuda clan to be created by the Dark Lord of Musphelheim, Azzendaer. With sanguine eyes and masterful transformation abilities, he was an assassin of the highest caliber, capable of taking the forms of anything that walked on earth, his disguise so believable that even Seraphims couldn't see through his deception. With that, he walked the earth, slowly corrupting the minds of all humans, elves, dwarves, and wereanimals with his insanity-inducing stares. A monster of sabotage, hundreds of thousands of knights hunted for him, but his shape-shifting prowess insured that he was never captured.

Back then, at the age of 432, he was a twisted monster in every single way.

His 999th mission from Azzendaer was to corrupt and convert the Thousandth Star of Astopol, one of the three thousand swordmasters who could make a contract with the spirits of the earth and fight on par with the demonic beasts that ravaged the lands of Ria'Lanv. Infiltrating the camps through his disguise as that knight's squire, whom he had dispatched of before hand, Jay became that knight lady's apprentice, learning the way of the sword and holy arts, so that one day, he would become the successor to her name. And even though his eyes were still red, even though he tried his best to infect her mind with corruption, his efforts were in vain. She stood firm and ignored his mental attacks, never even appearing to notice them.

No, it was more than that. Slowly, Jay's own view of the world began to change. He began to question the reason of his own existence, began to ask himself what HE wanted. He wanted to understand why demons wanted another world for themselves anyways, when Heaven, Earth, and Hell were basically all the same, albeit warped to suit the needs of their primary inhabitants. Under her guidance, he began to grow and change, for the first time since he was created. He became a respected swordsman, even though it was merely a disguise, and for the first time, he felt something akin to pride. The salvation of the humans just seemed to make him feel better than the corruption of them.

It was on his third year as her squire that she fell in battle, shielding him from the diamond-melting spray of the None-After Serpent. In three seconds, her body melted away, leaving nothing behind. No corpse to bury or burn. No memento to keep or treasure. Because of the salvation of a demon, she killed herself.

Jay should have been happy, and indeed, part of him did.

Yet the other part of him was dying on the inside, crying out in sorrow, raging for bloody, merciless vengeance.

That day, in heaven's stead, the demon smote the Serpent with a sword of blinding light, blessed twentyfold by the angels that he should have been fighting.

That, was the birth of Jay Lowell, the knight with a demon's heart and heaven's sword, an outlaw that walks his own path now: that of the destruction of Azzendaer, the Invincible Demon Lord that sits on the throne of Sandiltus, guarded by an elite echelon of demonic warriors.

His path is righteous, but his ways aren't.
