She Lives Well with the Shopping App in the 80s - Chapter 832: Attending My Aunt’s Wedding?

[Warning: Mature content, lemons, comedy, face-slapping, and a smart protagonist!]“So many beautiful girls!”After an unfortunate science experiment gone wrong, 25-year-old virgin Ren Kisaragi, wakes up in a strange new world.A world where curses manifest as eldritch horrors, bringing destruction with every breath.A world where female weavers command the very laws of reality and bend the elements to their will, while male warriors, blessed with monstrous strength, can shatter mountains with a single blow.It doesn’t take long before he realizes he has reincarnated into “Mystic Chronicles”, a fantasy novel he once read and dropped out of boredom.However, he isn't the protagonist or even a side character, he’s just a nameless extra, a mere background figure destined to fade into obscurity.But there’s one problem. He’s somehow enrolled at Imperial Academy, the most prestigious weaver academy in the kingdom… which is supposed to be an all-girls school!And as the only male weaver in an entire academy of talented (and terrifying) female weavers, his existence alone is enough to shatter the balance of the world.With a suspiciously broken cheat, an entire school of powerful and competitive girls watching his every move, and curses lurking in the shadows, Ren must navigate this chaotic new life before he gets caught up in a story that was never meant to include him.But maybe—just maybe—he can turn this anomaly into an advantage. And if fate allows, fulfill his lifelong dream of being surrounded by beautiful, ambitious women while he's at it.Can he survive this world where he's the ultimate anomaly?

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.

I killed the protagonist.Yeah. He was a real son of a bitch.Noah didn’t just stumble into this mess. He walked straight in—grinning, sword in hand.One day, he wakes up inside his favorite game… as a throwaway side character no one remembers. A complete nobody. But when he figures out who the so-called “main character” is?Some smug, self-righteous psycho.So yeah—he killed him. No regrets.Story over, right?Not exactly.Because this world? It’s got one more player.“WHAT THE FUCK IS GOING ON!?”Now the story’s off the rails, the world’s gone completely off-script, and Noah’s got a new goal:Steal the hero’s spot. Rewrite the plot. Find out who the hell this other player is. And maybe—just maybe—make this damn story fun for once.

It’s a affair between a loyal dog servant and his master.
