Botsuraku Yotei no Kizoku dakedo, Hima datta kara Mahou wo Kiwamete Mita

Synopsis:

Liam Hamilton isn’t quite what he seems. Outwardly, he’s the son of a declining noble family, but inside, he’s really just a lowly peasant. One night, he’s a down-and-out middle-aged commoner nursing cold beers at a tavern and the next morning, he wakes up as the youngest son of a noble count! How did this happen? Liam has no clue. But one thing’s clear: as a noble, he finally has the chance to pursue his lifelong dream of mastering magic. Trouble is, the noble house he’s been reborn into is on the brink of ruin unless they can prove their worth to high society. When Liam discovers his natural talent for magic, will he be able to save his family’s legacy, or is he destined to fall back to his former life as a commoner?
