   Summary

   For eleven years, Ishigami Senku has stood by Asagiri Gen's side.

   Guard. Shadow. Protector.

   As the heir of the last Shogun, Gen's life has never belonged to him, and as the world beyond the estate's walls begins to change, the cage around him only grows smaller.

   Senku was ordered to keep him safe. Getting him out might be the same thing.
