- Description from Novelupdates

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.'
