“You will suffice.”Raizen heard those words the night something chose him to survive.He doesn't know what whispered inside his head. He doesn't know why. But ever since that night, his life hasn't been entirely his own. Something marked him.Now he walks a beautiful world built on even prettier lies, where Eon turns desperation into miracles, Luminite weapons twist the laws of what's possible and what's not, and where humanity has been fighting creatures of shadow - Nyxes - for as long as anyone can remember. Though sometimes, the cruelest of enemies aren't made of darkness at all...But Raizen is starting to realize: the monsters aren't the only things hunting him.Something primordial is watching. Waiting. Pulling strings he can't see.If he wants to survive, he needs to get stronger.If he wants answers, he must become someone even the nightmares fear....But to win?He may have to end anything in his path - and pray he doesn't give the whisper exactly what it wanted all along.

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens! A scientist’s goal is to explore the secrets of the universe, and this is exactly what Leylin sets out to do when he is reincarnated. Dark, cold and calculating, he makes use of all his resources as he sets off on his adventures to meet his goal. Face? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Alternative: Leylin is transported from an advanced technological era into a medieval world— except there’s magic. Equipped with “only” his quick wits and an A.I. chip fused to his soul, he sets out to become the most powerful magus the world has ever known. In a land divided into the Light and Dark Magi, the weak can either be cattle or disposable slaves. Only the strong can determine their lives, and only they have the luxury for virtue. Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.
