“My name is Shun Satsujin. I'm an orphan… and someone who died only to be reborn into a world filled with fictional stories I once knew.”I expected a cheat ability—something powerful or overpowered. But all I got… was an intense exercise method called Herculess Method and a challenging life.Now, I'm just trying to survive and stay on track.That was the plan—until I enrolled in Shuchiin Academy.And suddenly, I found myself surrounded by girls from anime I used to watch.One by one, they started getting involved with me.

A young man that was always cautious with his life ended up dying in the most random way possible, buried by an avalanche.

As he died, within his last moments, he heard several mechanical voices resonating inside of his head, and he was granted many wishes in the form of Skills, Fortunes, and a new Body.

Now, reborn as an Ice Dragon, he is thrown into a world of fantasy that seems way too much like Norse Mythology named Yggdrasil, which is also, somehow, a Cultivation World?

What a weird mashup of concepts!

Accompany him as he explores this world, survives against the deadly monsters that roam this world, and fights to find a place to belong to, and a purpose to this new life.

However, he is not the only Reincarnated who was given wishes, and soon enough, the world he was thrown into will be engulfed in complete chaos.

Born with a silver in her mouth, she suffered a fatal betrayal. Not only did she lose her family property, but also her parents died a tragic death. Reborn, she won another chance and some superpower. This time, she would take back her everything and repay the last man she wanted to see in her previous life. He was the youngest major general in history and the most charming one among the presidential candidates. Now that she wanted to make up for it, he would never let her go.
