Shirokishi literally translates to "White Knight". Shirokishi is first shown as he is traveling to find the "King Knight Sword". Shirokishi speaks in an old-samurai dialect and shows great respect toward Pietro and Narcia. He is extremely skilled in swordsmanship despite his appearance, and also he's very kind and likes to help others (this was the main reason to help everyone he finds in trouble).
