Ryōdoji Family

The Ryōdoji Family began as one of Soul Society's noble houses, remembered in that age as the House of Ryōdoji. For reasons never made clear, the family lost its elevated standing and was banished from the realm for good, at which point the word "Fallen" was fixed to its name. Severing every tie to their former home, the survivors abandoned the Ryōdoji identity and came to be called the Dark Ones instead. This is a movie-original group introduced in Memories of Nobody.

Cut off from Soul Society, the family's last members rallied behind Ganryū and took shelter in the Dangai, the passage that lies between worlds, until they stumbled upon the Valley of Screams. There they found the Blanks, the lost souls dwelling in that place, and bent those beings' power to their own ends. Driven by bitterness over their exile, the Ryōdoji fixed on a single aim: the destruction of the realm that had discarded them.

Ganryū heads the fallen house and leads the Dark Ones, with Riyan acting as his second in command. The remaining members, Jai, Benin, Bau, and Mue, fill out the group. Every one of them ultimately meets their end over the course of the story.
