Leylin Farlier transmigrates into the body of Issei Hyoudou. What could possibly go wrong?
It didn't take long for Issei to make Yuuma spill.
It was obvious that despite her experience in torture, that she had never been tortured. By the time he was down, she was bawling on the ground from all the pain she was experiencing.
Of course, she stopped crying when he used his Boosted Gear and snapped her neck, killing her instantly. After all, if Issei let her go, she could come back with her allies and attack him again.
Storing her body in a space seal for research purposes, he went over the information he had learnt. Despite the fact that she tried to lie multiple times and tried to appeal to his morality, Issei was ruthless and used his A.I. chip to catch her in the act and then punished her.
It had taken a long time, but the information was well worth the wait. It had filled in the many gaps in his knowledge and allowed him to paint the bigger picture.
For example, he learnt about the three factions, which were the Devils, the Angels, and the Fallen Angels.
Yuuma or Raynare, was a member of the Grigori, an organization of Fallen Angels, and tasked by her superior, Azazel, to watch over people who contained Sacred Gears. Her other allies were currently based in the abandoned church near town.
She had technically broken the non-interference rule of Azazel, their leader, by trying to kill Issei, making her a rogue, which allowed Issei to kill her without fear of repercussion.
He had also confirmed his suspicions about the Student Council and the Occult Research Club being weird, as they were a part of the Sitri house and Gremory house of the Devil faction respectively
But the most important information he learnt was about the Sacred Gears. Sacred Gears were given to humans by God of the Bible to fend for themselves against the other factions.
The red gauntlet he had on was also a Sacred Gear, the Boosted Gear, one of the thirteen Longinus. The seal on it was meant to seal Ddraig, the Red Dragon of Domination.
Although Raynare had sneered at him and referred to his Sacred Gear as the weakest Twice Critical, he knew that he had the Boosted Gear. Though he allowed her misconception to continue, as informing her had served no advantage.
Despite having the power to kill gods, Issei's main worry was about his opponent. Apparently, he now had a death feud with Vali Lucifer, the owner of Divine Dividing, which housed the Albion, the White Dragon of Supremacy.
He was also the strongest wielder in known history, trumping his predecessors with a large margin. Issei frowned at the prospect of facing such an opponent, not because he thought he would lose, but because he found unwanted conflict to be troublesome.
By the time he had finished mulling over this information, he had already arrived home. He lied to his parents that Yuuma had stood him up and that he had gone to the arcade on his own.
His mother tried to support him, no doubt wanting to avoid him returning to his woman obsessed phase. It had taken a lot of effort to convince her that he had matured, and he wasn't going to change that impression, even if some of those magazines were pretty good.
Arriving at his bed, he made his A.I. chip make two more files, one for Senjutsu, and one for Touki. Apparently, you either needed to be super talented or a youkai to use them. However, Issei had an A.I. chip and could easily go over that hurdle.
He went into a meditative position and made his A.I chip make regular scans for any type of change.
It had taken over an hour, but something did eventually happen.
[Beep! Discovered an unknown energy source!]
He had finally found how to use Touki.
With a satisfied smile, he went to sleep. He needed energy for tomorrow.
