Matriarchy: After Their Identities Were Exposed, They All Panicked

Nickel transmigrates into a world where women hold power. To find a job for his useless older sister, he risks disguising himself and taking her exam in her place. He thinks he can get away with it, but on the day the results are announced, the princess in charge of the exam suddenly shows up at his door.

Scheming Princess Fiona: “Young Master Nickel, I’m sure you wouldn’t want your sister to lose this job, would you?”

Ducal Heiress Olishia: “H-How could it be him...? What am I supposed to do...?”

Sweet Princess Emilia: “Sister, don’t go too far!”

Archer Adventurer Luminas: “I’m sorry, Nickel. I was wrong back then. I’ll save you in my own way!”
