On his deathbed, the Great Philosopher expressed remorse, as he was never able to learn magic.

Five hundred years later, he was reborn as Mazel Loran, the son of a feudal lord. His family believe him to be a late bloomer in terms of his magic, but also think he’s the next incarnation of the Great Philosopher. But Mazel has a secret that nobody else knows: while he does not have any magic, he has experience with “physics”!
