From Vertical:
Reincarnated in an alternate world where magic rules all, a socially reclusive twenty-year-old is determined to build the perfect new life as a shut-in. But unlucky for him, his magical potential is deemed so ridiculously low that his royal parents abandon him immediately after his birth. Left to survive alone in a wild world full of magical dangers, the newborn prince manages to thrive against all odds because, little does he know, his true magic power is ridiculously off the charts.
