Transmigrated as The Forgotten Extra - Chapter 82 Returner from the border.

Accompanied by all kinds of crisis and despair, was the arrival of mankind’s first significant superhero.

Within the virtual world of “Avalon Online”, Finn, or otherwise known as “Echo” within the game, was one of its greatest players. After logging off from a long session, however, he notices something awry outside of his apartment.The streets were flooded with chaos, screams echo through the night, and hell is loot loose. Monsters from Avalon Online are running through the streets, wrecking havoc. In the midst of this hellish awakening, Finn is greeted with the one gift bestowed to humanity in this dark hour:[...Assessing life experience…][Assessment Complete][Name: Finn Thorne][Age: 20][Designated Class: Assassin][Starting Level: 5][A [Legacy System] has been bestowed to you for your accomplishments within Avalon.][Assimilation System Awakened.]In this twisted turn, as the world as it was once known is gone with the arrival of magic and monsters, the remnants of humanity must level up if they wish to survive.Finn is left in this dark, hopeless apocalypse, using his own experience from Avalon Online to best survive what seems to be an impossible task.

After I defeated the Demon King, I was executed for false accusations by the heroines.When I came back to life, this was the first thing they said.“I know it’s shameless, but would you help us one more time? Without you, the world will be destroyed.”…Would you help them if you were in my shoes?

An 11-year-old boy suddenly woke up,

“...wait, where am I?”

“...I see, so this is the so-called transmigration.”

“hahaha.....hellll yaaaahh.”

“It's my time to show the world who the boss is.”

But he didn't realize what he caused,

“Wait, this isn't what should be... why is he here, and where's that prostitute? And why is my lover with him?”

“Fuck, what the hell is happening here? He shouldn't be here, and that guy should be dead, but how is he alive....urgh,” he grumbled.

“This is MY FUCKING WORLD, why are these guys interfering...aahhhhh,” he shouted.

A transmigrator who thought 'doing good deeds and fighting against evil will make him a hero and ruler of this world' now made a very small mistake which leads to,

“My wife....is a wonderful woman,” the mob character.

“Why? Why? Why? Why......” the mob character rumbled.

“Do you....believe in god?” the mob character questioned with a messed-up expression.

“S-Shall we get m-marry?”

“...” the mob character was shocked.

“I don't know why but I like you, I guess.”

“....” the mob character was too shocked.

“I like you, so be my son-in-law?”

“....” the mob character was too-too shocked.

“How about marrying my daughter and me at the same time?....what do they call that hmmm...'oyakodon,' right?”

'cough, cough.'

“What?” the mob character was finally snapped.

“Big Brother, when will we get married?”

“........”

Transmigrator never expects a certain 'Mob character' and how that 'Mob character' becomes a great disaster for the entire world because of his single mistake.

A/N: This is my first time writing, so give me your honest opinion whether it is good or bad, but please don't be harsh on me... okay, I will try my best.

CHOTTO MATTE....The first five chapters, The Transmigrator will be one to explain everything about this new world. I know I am not introducing the MC suddenly, and it's hard to info dump, but it's just for the first few chapters, so don't be harsh on me.

If you wondered who will be MC then, MC is just a 'Mob Character.'
