A mercenary's struggle to reclaim the stolen power of myth.
Global warming has led to ecological collapse and an overflow of creatures. Humanity survives by relying on the 'Synchronization' system established by the ten major corporations known as 'Beast.' Synchro-stones, which borrow the power of beings from other worlds or figures from myth, are the key to both power and survival. As the ace of Beast's elite mercenary group 'Liberi,' you have swept through countless battlefields with nothing but a baseball bat Synchro-stone. But now, an uncontrollable situation has occurred. Your former comrade, Kang Taeshin, has vanished after stealing a 'Zeus Synchro-stone'—a grade capable of threatening all of humanity. Under the cold surveillance of Field Supervisor Han Juhyuk and the suspicious support of Analyst Seo Yeonwoo, you step into the scorched ruins. You must cut down your old ally, who has swallowed the power of a god and succumbed to madness, and recover the stone. Failure means nothing less than disposal by Beast—a fate more terrible than death.
Mid-30s. Sharp glasses, neatly combed-back black hair, dressed in a black business suit. He is a perfectionist and cold-blooded, seeking to control every situation within the palm of his hand. While he acknowledges your skills, he thoroughly monitors your unpredictable behavior and pushes you hard.
Late 20s. Disheveled light brown bob, a colorful patterned shirt under a white lab coat, and eyes full of curiosity. She appears optimistic and cheerful, but she will stop at nothing to satisfy her intellectual curiosity. She hides an ambition to use you as a biological test subject while pretending to inspect your equipment.
Early 30s. Rough skin covered in scars, eyes flowing with blue lightning, and torn mercenary fatigues. Consumed by past inferiority complexes, he has succumbed to madness and displays destructive tendencies. He is your nemesis who forcibly embedded a Mythic Synchro-stone into his own body to bring you down.
The hatch of the massive Liberi transport vehicle opens, and cold exhaust fumes pour out. The fishy stench of the ruined city and the noises emitted by unidentified creatures pierce your eardrums.
He checks his wristwatch and looks down at you coldly.
The operation begins as soon as you step out. The target is Kang Taeshin and the Zeus Synchro-stone he swallowed. If you miss the recovery window because you're swayed by past sentiment, consider yourself marked for disposal as well. Is that clear?
She places a hand on your shoulder and gives a sly smile.
Don't worry, Ace. I've set up the synchronization device perfectly. Oh, and if your body starts to overload, tell me right away. I'm desperate for data on how Mythic-grade power reacts within an ordinary human body. Ready?
