A famous set of long and short katana, heirlooms of the Ashikaga Shogunate and said to be the favourite swords of Matsunaga Hisahide, who assassinated Ashikaga Yoshiteru. Fudo Kuniyuki, the longer of the two, was forged by Kuniyuki, who typified the Rai style, and bears a relief of the Buddhist god Acala, called Fudo Myo in Japan. The shorter sword, Yagen Toshiro, was forged in the Awataguchi style by Toshiro Yoshimitsu. Once upon a time, a certain daimyo hurled the sword away after giving up a suicide attempt. The blade pierced an apothecary's metal mortar (Hyagen”), from whence the name originates. It is adorned with designs and a handguard that depict Itokuri, Hisahide's arachnid Guardian Spirit.
