Light Novel/Volume 1

This is the first volume of the light novel series, The Eminence in Shadow (陰の実力者になりたくて！).

Synopsis
Even in his past life, Cid's dream wasn't to become a protagonist or a final boss. He'd rather lie low as a minor character until it's prime time to reveal he's a mastermind...or at least, do the next best thing— pretend to be one! And now that he's been reborn into another world, he's ready to set the perfect conditions to live out his dreams to the fullest. Armed with his overactive imagination, Cid jokingly recruits members to his organization and makes up a whole backstory about an evil cult that they need to take down. Well, as luck would have it, these imaginary adversaries turn out to be the real deal— and everyone knows the truth but him!

Prologue
Ever since his past life, Cid Kagenō had always revered characters that were in the role of shadow brokers in a story for as long as he could remember, unable to recall the origin of such adoration. To become a strong mastermind, he mastered many forms of martial arts and weapon disciplines while playing the mediocre background character. One day, Cid concluded that there was always someone stronger, and even he couldn't survive a nuclear weapon. Thus, he sought magic to defeat that last obstacle, and dived into the depths of lunacy. Striking his own head against a rock, he saw two lights beckoning him forward, finding magic at the moment of his death before being reincarnated in another world. As a baby boy, his new life was in a world not too dissimilar to medieval Europe, now able to see magic as light particles. Cid was again ready to become an Eminence in Shadow, focusing his concentration to control his muscles to tighten himself from pooping, crying to alert his caregivers to change his diaper.

At ten years old, Cid is stronger and more capable than his past self, but still places the weapons of Earth in his mind as limits to overcome. Cid was born into a lower Dark Knight Noble family, those who use magic infused swordsmanship for battle, and resumes his role as a background character. Living as an average apprentice, Cid found the fighting and weapon styles of his past life were substantially superior to what passes for combat in his new life. While the styles of his past life were universally accessible and refined to simplicity, his current life has limited techniques restricted to their countries of origin, so their secrets are kept. With the isolation prohibiting interaction to improve, Cid deemed these practices "unrefined," with magic the major compensation. If magic were applied to the martial arts of his past life, the comparison would not be real anymore. Magic speed was used to close the distance between fighters, a key factor against reading an opponent at an appropriate range, as closing the distance before the opponent can react compensates for a lacking defense. Cid had secretly refined his skills so that, even at a one millimeter distance, he can change the battle's outcome, able to master anything with his magic control.

At his family home, his father directs him and his sister big sister, Claire Kagenō, on how to spar. As Claire has natural talent, it wouldn't be uncommon for her to take over the family, as magic is an equalizing force between the sexes, but Cid loses to Claire to maintain his background character status. Between aristocracy lessons and duties as a Noble, Cid only had time to train at night, using magic and meditation to compensate his reduced sleep. Periodically hunting bandits, Cid learns a band of rogues have camped at a nearby ghost town, glad to vigilante and eager to test his new Slime Bodysuit. Cid's research found magic is 90% lost when using regular weapons, casting 10% magic, but Slimes carry 99% conductivity and their liquid state provides limitless weapon shapes, as well as being lightweight and silent as apparel. The bodysuit is a simple coat, but can be refined in the days to come.

A disguised Cid crashes the thieve's banquet, slaughtering them wholesale with his versatile bodysuit, and fighting the skilled bandit boss last, testing his suit's functions before killing the leader. Examining the loot, Cid happens upon a mutated mass of living rotted flesh, someone afflicted with "Demon Possession." Since the Church buys the infected to execute while the public cheers them for "keeping the peace," it wasn't so different than Earth's middle ages. However, Cid detects a magical overload in the blob surpassing his own magic, recalling a previous magical overload that Cid resolved years earlier. Having not tested the effects of magical overload on himself, Cid is excited to have a test subject to safely test magical overload without risk to himself.

After a month of experimentation, Cid unintentionally returned the blob to its original state, a blonde elven girl. While Cid initially allows her to leave, she explained that she had no home to return to, so he recruited and renamed her Alpha to be his subordinate, and "elaborated" his mission. Recalling a tale, Cid stated his mission is to prevent the resurrection of the demon Diablos, defeated long ago by the Three Heroes, who cursed their bloodlines with the disease known as possession. Once protected to be cured, someone twisted history and warped facts to mold the descendants into objects of scorn, as they carry immense magical power and also carry the demon's power. Thus by being "possessed," Alpha lost her home to a false narrative. Cid then tells an angered Alpha that their enemy is the Cult of Diablos, who operate behind the scenes to revive the demon, and so they must as well to hunt them.

As the Cult likely holds positions of power, Cid invites Alpha to join him and she accepts, determined to avenge her injustice. Cid knows he made up the story, but is excited to have Alpha and can slaughter criminals with the "Cult" accusation. Cid dubs their organization Shadow Garden and Alpha aims to recruit more hero descendants to their cause, while Cid is secretly content with just him and Alpha. As he trains Alpha, Cid is astonished at her incredible aptitude despite only recently being a novice, and they continue training as Cid thinks about their improving skills.
