- Description from novelbuddy

I’ve become a rogue lord in another world! This is the story of a game I was playing! The story of the protagonist, who has become a rogue lord who dies after two days, successfully uses the game’s history and system to escape his impending doom and become the strongest.

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.

Razé was a cheat soldier at the age of 15, thanks to the memories of her previous life. One day, she was summoned by her superior – the devil Prime Minister and was ordered to go on a long-term solo mission. She was expecting a harsh mission, but…

“I knew you are the right person for this, Lieutenant Colonel Razé Orphan. I want you to attend the Centrior Imperial Magic Academy starting from this spring.”

“…..what?”

Well, it seems that she has been appointed as the “bodyguard” for the prince and other noble’s kids. And so, she was enrolled to the school where the aristocratic-sama gathered.

Although she was puzzled by the glittering school life, she was trying to live a life so as not to be bullied in the future. But it seems there was a secret that she didn’t know hidden in this world.

“Hey!!!!!! No one told me that this is an otome game!!!!!”

As a bodyguard, her life would be over if any of the noble kids got hurt. But then a young lady who claimed to be the ill-fated villainess came by. If the girl died, won’t she be dead too?

Today, Razé will continue to watch over her school life (with her own life on the line).
