Anyone know any good novels where the MC is either physically or Mentally (As in transmigrated into younger body, NOT just 'they grew up fast') Older. around early 30s s to early 50s, and ACTUALLY ACTS LIKE IT? I know there are some older protags out there, but it seems to be that they either give the excuse that their "younger body is influencing them" or they are just naturally immature. I know this one is a bit hard to pin down, though keep in mind I looking for one where they are like this at the time of transfer, not just "later in the story". EXAMPLE: Release that Witch Risou no Himo Seikatsu World Teacher – Other World Style Education & Agent NOTES: 1): Decent Length (30+chapters or 3-4 Volumes, depending on how its organized), and/or being actively translated (Has been updated in the last month). I.E. I don't want something with 10-15 chapters that's not been updated since August 2016, but something with 5-10 chapters that's been update last week(or even Feb) is perfectly fine. 2): No Hentai/Smut. Adult themes are fine, but no blatant smut. 3): Preferably NOT from RRL. My Computer does not like that site for some reason. 4): NO Xianxia style stories please.
What about something like The Chronicles of a Lost Man in His Forties Founding a Nation ? He does not get a younger body though.
Anyone have anything else? So far, from the ones suggested, things like World Teacher – Other World Style Education & Agent and The Chronicles of a Lost Man in His Forties Founding a Nation ~Commonsense is Hindering Me From Becoming TUEE~ (that name though.....), are the closest to what I am looking for. Things like God of Music are similar but not quite what I want.
Tales of the Reincarnated Lord(40's or 50's), Reincarnator(70's), Emperor's Domination(millions), Dragon Maken War (30's), I am the Monarch(30's), Main Character Hides His Strength(30-40's), The First Hunter (early 30's), The Amber Sword (late 20's early 30's). Can't think of others off the top of my head that actually act their older age. My Wife is a Beautiful CEO is worth a read although the MC is only in his early 20's he knows and has experienced enough that most of the time he acts older and jaded although he also doesn't care about a lot of stuff as well which other characters think he's immature sometimes.
