This fanfic is just wish fulfillment, Gary stu Fanfic with poor grammar, read at your risk. This is just fanfiction, don’t think too much. Please just enjoy! Maybe a Harem focused story. and the word count is short too… It's more like 10001200 words per chapter and I will post this daily hopefully. Ah, there is a spoiler in the synopsis and I don't recommended who still not reading Oshi no Ko to read this Fanfic. This FF contained, Oshi no Ko, Kaguya?, Love Live, Hololive (because I want it) and any other anime I like… Or any vtuber I like too… Why not… —------------------------------------------------------------------------------------------------------------------ When I woke up I was in heaven since I woke up in the arms of a beautiful woman with bluepurplish hair. Hm… But I wonder why there was a star in each of her eyes… Hm… It looks like she called me Aquamarine. Hm… It looks like I was reborn as a baby… Hm… It looks like I have a twin sister… Hm… It looks like my twin sister is also a reincarnated person… Ah… Isn’t I reincarnated as one of MC from the manga called Oshi no Ko, in which my beautiful mother would die at just 20 years old. There’s no way, I let that tragedy happen in my reality… and I will smack my father by my own hand by becoming a successful person in this entertainment world with the help of knowledge from another world!
