Thirty years ago, Vince Pearce is human and a mage, a criminal mage that is. He has a talent that is just below those who are deemed as a genius. But when experienced and acquired the power of magic, he got drunk on it real fast. He robbed, murdered, raped, and many more with the help of his magic.
He got discovered when someone finally felt suspicious about him and reported to the Mage Association with some incomplete evidence of his atrocities.
Vince's name is already high up in Mage Association's list of suspected criminal but no evidence found when he was reported. So when they got a little bit of evidence, the Enforcement Department of the Association immediately took off and searched his whole mansion and few of his known safehouse.
With everything searched, they found a large number of stolen items, in addition to this, they found many corpses; skeleton, rotten, and fresh, most are young women.
The fresh corpses were easily identified as missing women, and all of them are, to some degree, pretty.
The Association immediately issued a manhunt and a large bounty on Vince's head. They almost had him, when he suddenly disappeared, but in fact, he was helped by a devil with considerable high rank.
This devil is one of the believers of evil, those devils must strive hard to bring chaos to the world. He and Vince got along well due to their views in life. The devil Vince reincarnated as one of his own and took on the position of bishop in his peerage.
Vince's actions got obviously worst, but that didn't take long when the other devils in the Underworld got fed of his master's action and took action against him. He, without any hesitation, betrayed him and escaped. The Underworld dubbed him as a B-rank stray devil and another bounty was placed on his head.
He returned to the human world and went into a killing spree, eating human flesh and soul to strengthen himself.
He then joined an organization named Khaos Brigade and was sent to Kuoh Town to investigate its ruler, a high-class devil, Cleria Belial, and her lover, an exorcist, Masaomi Yaegaki.
It made him laugh when he heard that a high ranking devil is in love with a human and an exorcist at that.
He used the abandoned factory as his temporary base of operation while he is in Kuoh Town. There are already few people who trespassed this place for all different reasons and he did all the same thing to all of them, killed and eaten.
One day, when he is done investigating for the day, he notices three kids trespassed this time around and he thought everything would be the same as the last time. But a child, who introduced himself as Urahara Kisuke destroyed this notion. This child looks like an 8-year old kid with a kind of messy light blond hair, almost pale which is quite rare.
Vince, despite his atrocities, is an experienced mage and fighter. He already fought with angels, fallen angels, youkai, and other devils. He knows for sure that to use magic, you have to construct a magic circle as the source of the spell's 'logic' and pour your mana, demonic power, or holy powers to activate it. Of course, there are exceptions to this, bloodline abilities which belong to a high class or top noble beings of this world, Sacred gears that go with human reincarnation, Treasured tools that some factions keep, and Senjutsu(Sage Arts) that make use of natural energy in the atmosphere.
This Urahara Kisuke just completed a spell of a lightning system that is known for its destructive nature with a single word and easily pierced through his strengthened body. The fuel for this spell seems to be mana, but there is something different to it as just in the presence of this 'mana' put pressure to soul directly, and this scared Vince since this is the first time he comes across this kind of magic, not even from the records of magic in his master's gigantic library.
Maybe he only missed it and hasn't read it yet, but it is impossible for this kind of magic which affected the soul just in its presence to remain unknown or completely unheard of. Even in his new organization that composes of different races, no one is capable of doing this.
"W-What are you!?" Vince asked in a panic. "How did you that!" He added.
"What are you talking about, devil-san?" Kisuke replied while slowly walking towards Vince, "I'm obviously a human child. As for how I did that, it is called Kidou(Demon Arts), and you don't need to know the specifics about that, just think of it as the magic that is fueled by my soul."
'A magic fueled by your own soul!? That's just one way of suicide! This bastard is really looking down on me.' Vince thought at Kisuke's answer.
"Your face tells me that you don't believe what I just said." Kisuke's continued with a light smile on his face. "Whatever, you won't live past today, just letting you know." Kisuke suddenly released his Reatsu(Spiritual Pressure) which weighs down everything in the vicinity.
From Vince's point of perspective, some unknown force suddenly tried pushing him to the ground and the feeling of imminent death became more pronounced. His instincts as a devil are already telling him to run away as fast possible and he had never been this close to death.
"AHHHH!!!" Vince shouted with bloodshot eyes, circles of green colored lines and strange symbols appeared in front of Vince, with it, balls of green-colored flames of various sizes materialized a second later and launched towards Kisuke.
"Bakudou No.44, Sekisho(Barrier)" Kisuke silently muttered onto incoming fireballs, and a wall of fuzzy light instantly appeared in front of him.
The fireballs hit the wall and a large explosion ensues which destroyed a part of the factory. Vince didn't look at the destruction and bolted towards Issei and Irina's location. Vince knew if he escaped outside, Kisuke will be able to catch him easily with the speed that he previously displayed, so he hoped to take the other two kids as his hostage, that is the only way he thinks he could survive this calamity that fell on him.
He easily reached the place where Kisuke hid the two, but they were nowhere to be found. He tried looking anywhere near that area, but he didn't even catch the glimpse of their shadow.
"You won't find them anywhere since I hid them well." Kisuke's voice finally resounded behind him. Vince looked back and saw Kisuke walk towards him amidst of smoke and debris while giving him a mocking smile.
Vince was shocked since even though he didn't expect him to die he expected him to be seriously wounded 'cause he used almost all of his demonic power for that attack, but he came out with just his clothes dusty and wrinkled.
"WAHAHAHAHAHAHAHAHA!!! Just die with me then." Vince's last strand of reasons was snapped and just choose to die with his hateful enemy. His body suddenly inflated trice of its size and it started catching green flames allover.
"Seriously? You gave up way too fast." Kisuke commented while looking at Vince's state. "Oh well, you could just go on your own, I don't really have a hobby of dying with some strange old man. Hako Okuri(Farewell Box)."
A transparent blue box appeared around the devil. Vince, along with the blue box disappeared and a large explosion was heard at a distance a few seconds later.
