Called the "100-Dan Karate-Master" in the martial-arts world, Shio lives at the Ryozanpaku dojo in between body-guarding assignments. Despite his ferocious appearance and aggressive fighting, Shio is generally friendly and fun-loving. Due to his frequent work as a high-end bodyguard, he speaks many languages in addition to Japanese, but ultimately is a man of simple pleasures who prefers to spend most of his off-time drinking beer.
