She was originally the young miss of the Marquis Estate, but became a peasant girl due to a mixed-up at birth.
With great difficulty, she grew up into a delicate beauty, but no one wanted to marry her.
Rumors said she was ugly and was born a fool, and that she was a star of disaster that brought about the tragedy of her parents.
However, the husband she picked up midway was the future Grand Secretary.
The little monk she adopted from up the mountain was the future Godly General of the six states.

aIam terribly sorrya|a
A god was suddenly prostrating in front of Kayano Takumi. He was apparently killed by mistake. Moreover, he canat be reborn again. However, he is able to live in a different world? Then, letas do that, please. The god made a mistake again and transferred me into a dangerous forest. Seriously, whatas going on? Besides, there are children here. I canat leave them here, I will take care of them.

One day, I woke up only find out that Iad become a Demon Lord, an individual responsible for protecting a dungeon. The world Iad been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeonas defenses in hopes of living another dayaor at least that was what Iad thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.
This is Yukias story, my story. It tells the tale of how I spent my days after settling down in a dungeon with a self indulgent, asupremea dragon girl and a young vampire.

Suddenly appearing in a different world, it looks like I got caught up in a Hero Summoning. And of course, Iam not the Hero, but itas another guya|a|and while being very cautious and scared of the cliche of the cliche-like development, I was thrown into the maelstrom of wara|a|or not.
The Demon Lord? It was defeated a thousand years ago. Hero? Heas just the main actor in a festival. Nobles? Theyare kindly taking care of us. The Demon Race? They have good relationships with Humans. Wars? Itas already 800 years since the last one. Monsters? The Guild and Order of Knight are taking care of them. Return to Earth? It is eventually No-Risk.
What Iam planning after being caught up into this? Iam gonna enjoy the life in a different world as much as I want to, go on a cultural exchange and sightseeing, and after experiencing the festival that is only held once every ten yearsa|a|I shall go home safely.
The other world wasaaat Peace.
A kind world where the three races, the Spirit Worldas Magical Races, the Celestial Worldas Divine Races, the Mortal Worldas Human Races, they are kind neighbors to each other, with everyone living a peaceful and fulfilling life.
But although I wished to peacefully spend a year before my return, for some reason, the heavyweights of this world keeps gathering around me, anda|a|

To save the hopeless Dark Fantasy World, I held back my tears and destroyed the world, then killed the Demon King and returned.
Now, Iam trying to save the world using the aSystema I gained as a aRegressoras Privilegeaa| But the Main Heroines have also awakened their own memories of the previous timeline.
God damn it.
