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...

Reincarnation Tribulation - All I Want Is A Peaceful Isekai Life

Ah, so these are the flying Monsters I sensed that I didn't recognize through Thought Communication...based on their appearance, they're Sylphs.

Sylphs are Monsters with humanoid, translucent bodies with a faint, light blue hue that are highly fragile, with glowing light green slits for eyes. They have round heads and their jaws open wide, reminding me of Pac-Man.

Their bodies may be really weak, but they can generate their own winds and use it to surround their fragile bodies with a pretty strong barrier of wind.

They can also fire out powerful blasts of wind and are highly versatile fliers. And if they get too close to you, they can suck out all the air from inside your lungs and asphyxiate you to death.
