I'm not sure if this has been done before but just in case it hasn't
Anime/manga idea tm
I am just a tiny bit tired of the MC in isekai anime and manga being either a middle school student (+class sometimes) or middle aged adults going through a mid-life crisis.
INSTEAD, I would like the MCs to be a 60-80ish year old couple who were transported to a fantasy world (preferably truck-kun style)
Edit:
Expanding on this post, they aren't de-aged or anything. The only really noticeable thing being how they are quite a bit healthier and that their aches and pains are almost completely gone and that their memories are better. Otherwise they are just as normal as they were in their own world.
They don't have any OP powers or magic per sei just the knowledge of their jobs before retirement.
On that note, having one of them being a health care worker while the other does smthin involving machinery which causes them to get hurt often so they have a kind of 'Gets hurt x fixes them ' dynamic.
I feel like the storyline would be them just trying to live their lives in this new world but they keep adopting OP traumatised kids that they help and are in turn affectionately called grandma and gramps (or smthin).
