Reincarnated as a Loli Boss, I Drove the World-Destroying Generals Insane

Cecilia wakes up to find she has transmigrated into the ultimate final boss on the ninth level of the Abyss!

The Five Generals kneel and praise their Lord's wisdom, while all of humanity trembles in fear.

But her actual combat power is zero. She can't even unscrew a bottle of mineral water.

To keep anyone from discovering she's a good-for-nothing, she decides to stay quiet and act aloof, never move if she can help it, and spend every day sleeping, drinking soda, and eating potato chips.

Humanity sends an army to invade the Abyss. Their commander detonates a secret weapon at the cost of his life. She merely sighs before bed, and the secret weapon is erased from existence at the conceptual level, without making so much as a sound.

The human leaders stare at the surveillance feed, speechless: "The Abyssal Sovereign destroyed our ultimate weapon with nothing but a single breath!"

The Beast Emperor creates an ancient progenitor beast to counterattack the Abyss. She finds it noisy and casually says, "Quiet." The colossal beast that blotts out the sky immediately devolves into a golden retriever and lies at the foot of the steps, wagging its tail.

When the oldest god in the universe awakens and declares the Abyss a blight on civilization, it discovers that this girl, who never leaves home and only ever nods, is the true taboo of the Myriad Worlds.
