It's probably a situation of both of them being in different forms/lives each time. Ooma can only recall the one (for now?),Calling it, the twist is that she was reincarnated many times already, looking for her beloved demon lord each and every time. She has been many people, awaiting her beloved. She indeed doesn't clearly remember who she was way way back in the fantasy world anymore, but she remembers the love she felt.
I don't think their entire personalities stay the same after reincarnating, MC acts pretty much like a schooler girl that she is now, more childish and innocent considering she used to be the demon lord, that guy who used to be her subordinate only seems to be the same because rn he's an adult guy like beforeWeren’t they quite old when they reincarnated? What’s the ethical issue?
It’s like Jadzia from DS9, if she takes over a different body even of a different gender or age like this, (literally going from an old man to a young woman) people still treat them like their previous incarnations if they knew them, like with Sisko still calling her “old man”.
Kind of reminded me of that one yuri manga about a hero and a demon lord who loves each other and have been reincarnated so many times until they can finally be togetherCalling it, the twist is that she was reincarnated many times already, looking for her beloved demon lord each and every time. She has been many people, awaiting her beloved. She indeed doesn't clearly remember who she was way way back in the fantasy world anymore, but she remembers the love she felt.
