Adam harbors the smallest inner World ever recorded—a vessel so minute it becomes a curse. In this world, binding beasts determines destiny. Power flows from conquest and growth. Yet Adam's World defies all rules, all limitations. He possesses infinite potential, bound within an infinitesimal space. When his father returns with an egg, everything shifts. The bond ignites. Ether surges through his veins for the first time. Adam finally holds something tangible: strength. Now bound to a Soulkin whose abilities shatter convention, Adam must grow. Master and beast evolve together or fall behind entirely. The world is merciless—strength is the only currency that matters. Something stirs at the edge of the horizon. And the boy with the smallest inner World might be the only one beyond fate's reach—the only one it cannot bind.
