Its a story from the /vt (virtual Youtubers) board on 4chan that managed to spread to mainstream Hololive thanks to reposts by fans. Like many other 4chan posts, its most probably fake so people share the story as a joke.
I'm actually manipulating my wife into becoming Ina. I convinced her to take art lessons and lied that her voice hurts my ears so she could speak more softly. I picked her on purpose because she was a petite Korean girl with a flat chest: the perfect candidate. Lately I have been playing sounds during her sleep and whispering "the cucumbers will kill you only the ancient ones can save you" on weekdays and on weekends, I read a book full of terrible puns I found on amazon and to my surprise it worked. She now hates cucumbers and has started developing a wit for puns. She isn't exactly sure what "the ancient ones" means but she'll know when I'm done brainwashing her. Soon I will start subtly changing my body language around her to reflect approval towards outfits Ina would wear and things Ina would say. I've also been keeping her on a strict diet which keeps her slim while allowing her to drink Dr.Pepper or as I call it around her "Dr Oopsie". By next year the project should be done and I will hand sew her a replica of Ina's debut outfit so that I will be the first man on earth to try Ina's back in real life. I will then gift her a crowbar so she can gently bonk me any time i sekuhara her in our home.
