Transported to the world of spirits and magic, Ayumu becomes Fabian, a genius young mage. Too bad Ayumu himself has no clue about any of this magic gibberish! Can he keep up with everyone's sky-high expectations?!

Ayumu Shinohara is your run-of-the-mill high school student who doesn't stand out in any way. He couldn't be more different than Fabian Aes Berion whose body he ends up transported into.
Now that Ayumu is Fabian, can he keep up the genius mage's image, hone his magical craft, advance spiritual research, navigate nobles' schemes and—most importantly—meet everyone's expectations? Or will he get busted in the process and expose himself as a fake?
Thankfully, he has the assistance of Lucy, his loyal, seemingly emotionless maid, and Mary, his energetic but sharp fiancée!
...Except for the fact that tricking these two might be the most difficult part of it all...
Well, as they say: Fake it till you make it!
