Jitsu wa Ore, Saikyou deshita? ~ Tensei Chokugo wa Donzoko Sutāto, Demo Ban'nō Mahō de Gyakuten Jinsei o Jōshō-chū! - Chapter 21.2 - Dark Mysterious Organization(2)

Mo Chu was reborn. She opened her eyes to find herself in a world where a thousand years had passed. The docile animals and plants became very aggressive, and elemental abilities that existed only in stories and legends now appeared before her eyes! Fortunately, upon waking up, Mo Chu gained a nice-guy brother who had a sister complex. Unfortunately, she had a one-in-a-million sensitive constitution, so she couldn’t consume 99% of the available food. However, there would always be a solution. If she couldn’t eat the food of this era, couldn’t she come up with new food? And so, she made fries, grilled fish, beggar’s chicken, and various other delicacies that were not available in this future world. As a glutton, Mo Chu was satisfied with this outcome. However…

The era of the great pirates.

The sea is surging, the strong are destroying the sky and the earth, and they are fighting each other. It really makes people——

Can’t get up!

I, Rusilu Cullo, twenty-four years old, my biggest dream:

Live this life safely!
