Who Designed This Underworld Dungeon? - Chapter 25 - Bonfire ???

“With my knowledge, give me a fulcrum on which to place it and I shall move the world!”

An eternal prison, a soulless body, a sealed spirit, everything lost.

To resign before merciless fate, or to become destiny!

“I lived in an illusion, I was lost, I could not find my home, I did not have a home… but why does it matter?! Between bowing to the threat of death and a spine that would never bend, I will choose the latter!”

In her previous life, she rose from a country girl to become a CEO, working diligently until she died of overwork at 38, only to find that she had been greatly betrayed by her useless husband, who even had a child outside their marriage.When she opened her eyes, she was back to being eighteen years old, facing grandparents who favored boys over girls, a father who was honest and kind but dared not resist his parents, her mother who loved them deeply but was easily bullied by others, and her brother who still loved her despite her coldness.In this life, she decided to take her family away from those greedy relatives, save her brother from a fate of disability, and stay away from her useless ex-husband.Unexpectedly, she saved an even more important person by the roadside.“Your husband is just a country bumpkin; he didn't even get into university. How could you live well with him?” her ex-husband said.One day, a Bentley stopped next to her. A driver got out and bowed to her, saying, “Madam, the Boss is waiting for you for dinner.”“I know that car! It belongs to a rich family!” someone exclaimed.“Did he just call her Madam?” another person asked....“Did you hear? He brought a country girl home?”“They say that girl is his wife. Isn't it funny?”“Madam has arrived!” said the steward.“OMG, it's the talented girl from the famous university!”“Dear lord! She is the legend of the A-shares!”“I'm just so shocked...”“Hey, guys, she is my wife,” he said.

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.
