~PLOT~
“Finally, retirement!”
Ruin, a demon who spent his whole life working toward retirement.
And at long last, he thought he could finally rest.
“Your house has been turned into a Hero Academy.”
…Excuse me?
“In other words, your entire fortune is buried in that place.”
“……….”
A lifetime of savings, sunk into an enemy nation’s academy.
“Damn it, I’m going to get my money back.”
Cursing under his breath, he infiltrated the academy.
All to recover his fortune.
But then—
“Become my son-in-law.”
“Be the consort—no, the hidden power behind the imperial throne.”
“As a hero, I ask you: take command.”
…He ended up being way too good at the undercover professor job.
“…This is insane!”
Forget retirement—he’s only getting promoted.
