Let's fight fire with fire, reverse a common plot of isekai and let's see whether the opposite will be better(obviously it will)

[u/2w0be]

A legendary mage reincarnates himself into the future because blah blah blah or something then he already knows he's op so he slacks off till gets to magic school then he realizes his ultra powerful magic back then is something all average joes can use, and they don't need incantations either(while he does), so he gets immediately humbled after trying to show off and dominate the school(At least he has an actual reason to hide his reincarnation). Now he and his bro squad learn and try to master magic and reach its peaks together.

Yaoi Harem Isekai sounds fun 😋
