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.

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.
