Seriously, if one believed manga as accurate depictions of society you'd think that the population of Japan was like 80% sleazy pickup artists who won't take "no" for an answer, 9% beaten down loser salarymen who are struggling through life until they can get isekai'd so they can live a cheat-filled slow life in a fantasy setting, 9% beaten down loser students who are being picked on but all the douchy cool kids don't know that they're actually super smart and capable and when they get isekai'd they'll become heroes of the realm, and 2% beaten down losers who are actually secret psychos that will go off on bloody revenge tours when they get their magic powers/reincarnation opportunity.
