After accidentally falling, she actually finds herself bound to a Second Female Lead Counter Attacking System!

Anthony Saunders died an orphan, alone and miserable because of a pandemic disease, and was transported to another world as a farmer’s son named Anton. The surprising thing was there was a tattoo of his favorite game Diablo II on his wrists. He was able to enter the game even virtually and all spells and stats of equipped items will reflect in the real world but unfortunately, he can’t take items from the game to the real world. He could use the inventory though!The best part was his Diablo II icon had an internet browser that allowed him to surf the internet from his previous world, but he couldn’t communicate with anyone, just search, read, and watch using the browser, but it saved Anthony from the greatest affliction of all, Boredom!With all the information from his previous world at his fingertips, he should become rich right? Well…

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.
