So this morning before I went to sleep I was watching the first episode oshi no ko and it got me thinking as I was dozing off and at work about the anime reincarnation.
So pretty much as most people have already seen or read it. The doctor being murdered becomes the child of his oshi.
It got me thinking about something similar to Rudeus from mushoku tensei. Is the child a husk for a soul?
After he died in Japan, rudeus was reborn into the child of zenith and Paul. Similarly to what you see in episode 1 of Oshi no ko. They were born into a new body that they retained memories of their past life. The only difference being one gets isekaid to the fantasy world while the other is reincarnated still in the same world he came from.
Do you think that the kids are just husks readied for the MC that gets isekaid or reincarnated in said body or the soul of the kid gets overridden when the MC is given the body by the God of said world?.
