To Survive, I Have No Choice but to Be a Good Little Girl!

I'm a transmigrator, but where's my grandfatherly System?

I'm the legendary good-for-nothing protagonist, but where's the promised engagement-breakup face-slapping plot?

My mother is from the Einzbern family, so why isn't there a Holy Grail?

My name is Luna, but where's my Asahi?

I'm a little girl, so what do you mean by giving me a lollipop?

What! You actually want to flirt with me?

Sorry, mister, I don't mind, but that's three years minimum, and the maximum penalty is death!

P.S. This book is also known as Miss Nightmare Is Not a Little Girl!
