Calamity of Tomorrow - Chapter 303 - 302 Sorry, there was a timing error, updating only now.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

It was in the year 2800 of the Midgard calendar. Back then, there was a Overlord who once reigned supreme and had reached the very brink of subduing the world.

She was the Fifth Young Miss of the revered General’s Residence, but was seen to be useless as trash. Promiscuous and flirtatious to a fault, she was finally killed by mistake under the hands of the attendants of the man she was chasing; She was a genius favoured by the Heavens but ultimately murdered by an insidious plot and all who shared her bloodline pursued and exterminated which caused her to lust for revenge to be paid in blood. The day the genius had unwittingly taken up the body of that useless trash and opened her eyes, her fate had completely changed!!!

Refining elixirs and the smelting of weapons were tough?
That did not daunt her.

Beast Tamers were rare?
She had easily gained the title of Emperor Beast Tamer!

Forced marriages!?
Men being arrogant because they are good looking?
She stretches her hand out and easily pulls devilishly handsome men to her: The Demonic King brothers would easily take their place. A devilish glance, a slight shimmer of movement, and that man would suddenly disappear the next moment. He turned back around, his devilish smile alluring: “Let’s continue with the topic, let’s have a child!”

This is another interesting story with transmigrating and very fun filled characters that will delight you.
