Following a less than ideal life and a harrowing death, the protagonist finds himself in the presence of a God, offering him a customized reincarnation into a world of his choosing, with his memories intact 

He decides to reincarnate into a world of Magic and Monsters, intrigued by the notion of being able to use fantastical powers that did not exist in his previous world

Having grown up in a stifling high society and unloving family environment in his previous life, he chooses to reincarnate into a more simple life, opting to be a Commoner instead of a Noble, despite the oppressive class system present in the world of his reincarnation

Following a detailed customization of the powers he chooses to acquire, he reincarnates into a peaceful, loving family in this new world, with the name Larrk Stryker, in a small village well away from Noble society

While Larrk's fascination with Magic and the other powers he possesses in this world, along with the desire to be able to protect himself against any threat that might arise, drives him to master these abilities, all he really wants is a nice, peaceful life, one that's free of any strife or tragedy

But whether or not such a life can be achieved in this world, remains to be seen, as the countless unfamiliar elements of this strange new world only give rise to countless more possibilities, both good and bad...

<p>"Yes, I'm quite certain. Since your body was already somewhat superhuman from eating Monsters, you've grown significantly more powerful through this Contract than normal humans presumably would. As a result...it may be possible for you to form a second Contract with another Monster. However, another Demon, or a Dragon King or Elder Vampire, might be too powerful to sustain inside of you along with myself," He informed me. </p>

<p>"Well...just because I can form another Contract doesn't mean that I'll get the opportunity to do so. It's incredibly rare, I might even be the only human currently in existence with a genuine Monster Contract, so getting the chance to obtain a second Contract is pretty slim at best," I replied wryly. </p>
