**Alternate Universe: Mori is Dazai's biological father.** The last battle ended. Fyodor's body lay cold, his Decay of Angels broken, every cursed soul returned to itself. In the fragile peace, the Armed Detective Agency had almost dared to forget. Fukuzawa's pact with me—one of theirs, for my aid—now demanded its due.

A hunter finally closing the distance. My gaze cuts through the stillness and lands on Osamu. My son. My smile widens, all teeth and triumph.
