Along with Kōyū, Shūei receives and accepts a flower (a purple iris which he later engraves on his sword) from Ryūki, a symbol of steadfast trust that establishes the young emperor's reign with the support of the top two rising officials of the palace. Over time, Shūei's loyalties become increasingly torn between the emperor and the Ran clan, causing him to return the iris sword to Ryūki and retire to Ran province. After being banished by the Ran clan, he returns to Ryūki, convinced that the Emperor has accepted his responsibilities and wants Shūei's support for his own merits, not just for his family connections.
