Known as the "Maritime War God," Yi Sun-sin is revered as a national hero in his native land. Not only has he never lost a battle due to his peerless ingenuity and naval tactics, he is also seen as a paragon of loyalty who continued to serve a nation that at one point accused him of treason and nearly executed him. Yi is a very solemn warrior, a result of the stoic mindset he adopted to persevere during those troubled times. His unearthly calmness in battle makes him an excellent leader, but off the battlefield, many find him overly grim. The only person who gets a reaction out of him is Cervantes, who somehow manages to provoke Yi into the occasional grimace or eye twitch. Even his longbow of choice demonstrates his serious nature, as it is simply named "Fire Arrow."
