Yoshimitsu's beloved self-named katana was handed down through many generations in the Manji clan. It seems like a normal katana, but it has many unique features that accommodates the unique style of the Manji. Since it was forged with secret techniques passed down in the Manji clan, it cannot be replicated and is the last of its kind. Yoshimitsu, after the massacre of his clan, swore an oath of vengeance to this weapon. It has been tainted by the evil energy of Soul Edge and turned into a demonic weapon, but still is the preferred weapon of Yoshimitsu. The sword has the ability to divert evil energy and destroy a monument in only one blow. Apparently, it will not harm its wielder if its wielder shares its name.
