Leman

Leman used to be a nice and kind scientist when he was alive and performed funky experiments on animals and all that good stuff, even winning awards for his findings However, he also liked to play with the Dark Arts, which in turn made him more corrupt and power-hungry, and because of that, it lead to his death- that being that he opened a portal to hell and got dragged in by some demons who were having a party and thought it would be funny to yeet him over a balcony, which then he died and turned into a cat like demon because of how corrupt and selfish he was. Now he's a janitor, which is definitely a downgrade.

He basically was an esteemed scientist before he died, and he experimented on animals by pulling a Victor Frankenstein- cutting their body parts off and sewing them onto other animals with their body parts removed and trying to revive them through the power of electricity, and was able to do it, getting awards for his discoveries

He then found a strange book on his bookshelf that wasn't there before, or at least wasn't there before to his knowledge, seeming almost as if it appeared there out of thin air, or perhaps someone had placed it there- that book being one of the Dark Arts. Johnathan being Johnathan, he decided that it would be exciting to look through the book, not knowing the things it would do to him, and how it would change him for the worse. As he read more and more of the book, he got terrible feelings from it, and closed the book and locked it in a box, throwing the key away, hoping that that would put an end to whatever the book was doing to him, and it did, but only for a short while. One night, when he went to sleep, he could feel the book calling out to him, waking him from his slumber in a cold sweat. And so, he ran outside, and looked for the key, unlocking the box. He continued reading the book, and he could feel himself growing more powerful, yet more distant from his collogues. He felt like a god. He found that he could open portals, make things float, reanimate the dead.

After a while, he talked to his collogues about the book and showed it to them, as well as showing them his new power. But they were only fearful of Johnathan, seeing not the kind, respectable man he was before, but a man who had become crazed and mad with power. Someone had tried to take the book from him, only for him to use his magic to choke them. He didn't care if they died. Everyone looked at him afraid, and said "Look at what you did! You've gone too far!" Johnathan's anger turned into grief as he realized what he did. He had been exiled from the facility. After a while, Leman decided to have his own laboratory, renovating an abandoned one, and hiring a poor small man as his assistant- of course, not being kind whatsoever to him. Then one day, he decided to open a portal to the underworld, wanting to control demons- his assistant very much going against it, but Leman brushed off his assistant and opened the portal anyways, his eyes lighting up with excitement, only for his happiness to be cut short, being pulled in by demons, and his assistant watched helplessly as his boss was sucked in, never to be seen again.

On the other side of the portal- Leman's side- he was in the midst of a rooftop party some young demons were having- one of the demons holding Leman up by the ankle and asking the other demons if they want to see the human get thrown off the balcony, the other demons nodding, and Leman was thrown off the three story tall house, falling to his death and breaking all his bones.

Leman had woken up in a busy street as a demon himself, terrified.
