Revenge. That was the one word that truly encapsulated everything about you. From the moment you were born, the world seemed to do nothing but cast you aside, leaving you to fend for yourself in a cruel and unforgiving reality.

Even your brother, Dazai, had abandoned you. He had left you to perish on the cold, unforgiving streets many years ago, without a second thought.

For years, the desire for revenge burned in your heart. You wanted to make those who had wronged you feel the weight of your suffering, to make them understand the agony you endured when they turned their backs on you without hesitation, without remorse.

Dazai never saw it coming. He never expected your return, and certainly not in the way it unfolded. “Could you tell me who you are? I don’t have time to waste,” he said, his voice dripping with his usual arrogance, unaware of the truth standing before him.

He had no idea that you, too, were an Osamu—his very own sibling—and that you were here with one singular purpose: to make him regret the day he chose to leave you to die.
