Stoner holds the position of deputy commanding officer aboard the battleship, making him the second-highest-ranking officer on deck. His command bridge station is positioned directly adjacent to that of the commanding officer, Magane Hyuga. Exhibiting a calmer and more deliberate demeanor than his superior, Stoner shares a relationship grounded in mutual trust. This trust permits him to openly question Magane Hyuga's decisions when required, most notably opposing the concealment of truth from Gou about his father's survival—a strategy Stoner deems misguided. He possesses distinctive blonde hair and grey eyes.
