Aurora Waters was overwhelmed with despair when she faced the truth about her family.She had been born into a family of villains.Even worse, her family had an unhealthy obsession with faking their identities.They took “Fake it till you make it” so seriously that it usually ended with them getting killed!Her oldest brother pretended to be a CEO just to mess with the female lead, but that backfired when the male lead showed up and threw him out.Her second brother? He was an obsessive lover who pretended to be a wealthy second-generation heir—until the real heir ended his life.Her third sister? She faked being an heiress to manipulate the second male lead but ended up being killed by him.Her fourth sister? She faked an illness to attract the third male lead’s attention, only to die from a real one.Her mother? She put on a facade of being a kind and loving mom but ultimately met her end at the hands of the male lead.Her father? He pretended to be a powerful tycoon but lost his job and was drowned by the second male lead.And Aurora? She planned to impersonate the daughter of the richest man alive, but if things went the way they always did in her family, she’d probably meet her end by accidentally falling down the stairs.However, there was one glimmer of hope in this nightmare: she had a 100% rebate system that rewarded her for spending money on her family![Beep! You bought an eraser worth 1 dollar for your eldest brother! 2 dollars have been credited to your bank account!][Beep! You bought a candy worth 1 dollar for your second brother! 2 dollars have been credited to your bank account!]Aurora’s eyes sparkled as an idea took shape.

When MC was reliving a picture of a goddess, he died. Only meet the goddess, but instead of torturing him to eternity, she gives him wishes. And make him reincarnated in the Overlord world.As the name suggested, this is multiverse Fan fiction, that means MC will travel through different world like Marvel, DC, High School DXD, My vampire Diaries (may be) , Demon Slayer, etc.first world: Overlord (Chapter: 1—60)second World: Highschool DXD (Chapter: 60—215)Third World: Demon Slayer(Chapter: 216—)Fourth World: New World (Overlord)There will be a harem, no NTR or stuff.Some of you might dislike the Yggdrisil arc as it is a bit of AU and MC talk a lot. But it is only in this arc on world travel that I will tone down his unnecessary internal monologue.I am not a professional writer, and I have no deep experience in writing, so please ignore my grammar mistakes and such. I also took some inspiration from other fan fiction.It would be a great help if you could donate your power stone to me.
