In the Mushoku Tensei: Jobless Reincarnation thread I talked about it being the second isekai anime I have seen in which the MC was reborn in the new world, just this morning I remembered 2 more (As I type this, I remembered another show that might have done this, but the anime might have skipped the details to know for sure)
Though one of the 2 I just remembered, they were reborn, but didn’t have the memories of their past life until later on, they just woke up one morning was like “Oh! I died on Earth and was born in this life with extra powers that I asked not to have!”
