My Billionaire Idol Step-sister: Animeverse.

It all came all of a sudden.



My father got remarried.



And I got myself a sister.



"Wait! My stepmother is kind. And rather rich."



"My sister is the idol; I had always liked her for so long." [Just as a fan.]



"And with that, my high school life took a massive turn."



[I am a reincarnator and a genius to boot with an artist system.]



[So, what do you think?]



[Welcome to my story.]
