With the Imperial Army in hot pursuit, Housei leads Taitou and the others on a little detour to the home of his master. But the "mean old devil woman" he had described turns out to be nothing of the sort. Master Kouei is a veritable font of wisdom; in addition to knowing a more covert route into the capital, she is well versed in the legends of the Hokushin-Tenkun. There is much she can teach Taitou as he struggles to control the overwhelming power of his star, but will she have enough time to impart her wisdom before tragedy strikes? Hiromu Arakawa, creator of Fullmetal Alchemist, brings the legend to life!
