実は俺、最強でした?

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! Join Haruto, the socially awkward guy who just wants to chill out, as he navigates demon friendships, royal feuds, assassination plots, secret superhero identities, and having a little sister.
