In the 262nd year of the Dragova Era, melting polar glaciers and rising seas swallow countless nations. Ancient sea beasts awaken, invading human lands. On January 1 of year 263, the Rank-10 beasts strike humanity’s last territory, Taelsky. Led by General Alaric Thorne, the elite Dragova Squad fights bravely—but by March 12, they are all annihilated.

When Sophie Reed empties her every resource into a spirit summoning ritual, the universe sends her Leo Hayes, a cheerful young man in catastrophically loud floral shorts. The crowd loses it. Lowest-grade Contract Spirit in history, they say. What nobody knows is that Leo carries the Menace System, a power that feeds on breaking rules, shattering expectations, and generally refusing to behave. The more absurd, the more impossible, the more wrong he is by every known standard, the stronger he becomes. He slaps the original summoner clean out of the picture, casually evolves into the Divine-grade Contract Spirit World Heartthrob, and grins at a world full of rules he was apparently born to demolish.

Hank is transported to a world intruded by ferocious beasts, where men at 18 can become Beast Masters, while women awaken their bloodlines to gain beast abilities—these "beast-girls" are humanity's ultimate defense. Through contracts, men and women grow stronger together. Hank obtains a God-Tier Beast Master System, yet begins with the lowest-ranked talent, scorned and abandoned by his clan. Still, his partner Queen honors her vow to form a contract with him, and from that moment, Hank rewrites his destiny.

When the apocalypse hit, Alan Clifford sacrificed his lifespan to shelter humanity in an underground bunker for 30 years. But after peace seems near, he is betrayed by his adopted daughter Cindy Clifford and Chelsea Mason, who forge fake surface footage, incite the masses, and send him to the gallows. Believing their lies, humanity destroys the bunker and rushes upward—only to fall into a trap set by giants. As slaughter begins, Alan, now a master of mecha tech, must decide whether to save them again.

During a family gathering, my mother produces a few photos of different men. She asks me which one I want to get into an arranged marriage with. I don't choose Bradley Garvin again in this lifetime. Instead, I pull out a photo of my own and give it to my mother. It's of Terrence Garvin, the Garvin family's true leader. My mother is surprised. I've pursued Bradley for many years, after all. What she doesn't know is that I married him in my past life. However, he rarely came home. I always thought it was because he was too busy. Whenever anyone asked me about it, I took all the blame. I only discovered the truth on our 20th wedding anniversary after accidentally breaking a box he kept locked in his closet. It turned out my sister was the one he'd always loved. He never returned home because he didn't want to see me. Unexpectedly, Bradley loses his mind when I'm about to put a diamond ring on Terrence's finger on our wedding d

I accidentally awakened the beast recognized by the entire academy as the “weakest SSS-rank in history” — a soft, squishy, bouncy Slime.While this harmless, derpy little creature was mocked by all of humanity as utterly useless, and everyone looked down on me with scorn, the long-silent system in my mind suddenly lit up with world-ending warnings. That was the moment my comeback began.
