Tadayori Nagao was a legendary archer of Tsushima who lived centuries before the invasion. His lost armour is the prize of the Mythic Tale The Legend of Tadayori, and his last descendant, Kaede, guards his resting place.
By the time of the invasion nobody knew where his armour was, only the legend. Jin follows clues from Kaede to the cliffs above Azamo Bay to find it. Tadayori's Armor improves your speed and aim with the bow.
Kaede
Kaede is a female samurai and the last of Tadayori Nagao's line. She guards Tadayori's Rest and duels Jin when she mistakes him for a grave robber in The Legend of Tadayori.
Yamato
Yamato is a travelling musician and storyteller who starts most of the Mythic Tales. When you hear his music, he tells Jin an old legend that leads to a special technique, weapon or armour set.
