Matriarchy: Why Are They All Panicking After My True Form Was Exposed?

Nickel transmigrated to a world ruled by women. To find a job for his useless older sister, he risked disguising himself to take her entrance exam. He thought he could get away with it, but on the day the results were announced, the princess who had overseen the exam suddenly showed up at his door.

The scheming Princess Fiona: "Mr. Nickel, I imagine you wouldn't want your sister to lose her job, either?"

The duke's daughter, Alicia: "W-Why is it him... What should I do...?"

The sweet-voiced Princess Emilia: "Sister, don't be so mean!"

The archer adventurer Luminas: "I'm sorry, Nickel. I was wrong back then. I'll save you in my own way!"
