Tristan Shaw transmigrates into the brutal Beast Realm, only to suffer an immediate contract failure and betrayal from his girlfriend. He accidentally binds to a powerful cheat system and soon encounters his cousin, who has also transmigrated and is now the mighty fantastic beast Nightwyrm. With the System's help and the loyalty of several SSS-rank dragons he subdues, Tristan rises begins his rise to become a legendary Divine Beast Tamer, crushing his enemies and single-handedly quelling a catastrophic demonic beast tide.

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.

The world ended in water. In a single night, the seas swallowed the land and humanity was left drifting. Beck Zivan spent his first life as a security guard doing the unsung work protecting people, building rafts from nothing, keeping strangers alive. His reward? When the raft got too crowded, the people he’d saved threw him overboard. He drowned knowing their faces. Now, he comes back. This time, a Savior System takes root in him. Every life he rescues upgrades his vessel and grows his power. He begins preparing earlier, building smarter, choosing who he trusts more carefully. Gratitude will be returned. So will betrayal.
