Crushed by unbearable pressure and insurmountable debts, Kaito, a brilliant Tokyo engineer, makes the most radical decision of his life: to disappear. Through a clandestine agency that specializes in making people "evaporate," he leaves everything behind to become a ghost, reborn under a new identity far from the chaos of his former existence.
Just as he rebuilds a simple, anonymous life and believes he has found peace, the shadows of his past refuse to let him go. A relentless detective is hot on his trail, while an unexpected financial discovery gives him the means not just to hide, but to settle his accounts.
Caught between escape and redemption, Kaito must confront a far more complex truth: sometimes, the only way to be free is not to vanish, but to choose who you are truly meant to be.
