Kilauea Shulen was the mother of Sonya Shulen. One of the Scarlet Moon Empire's original Five Great Generals, Kilauea fought in the War of Succession under the banner of Barbarosa Rugner. She was known as a brave and resolute naval commander and was said to be a master of the one-handed sword.
Her role as the naval commander proved vital to ending the War of Succession quickly, as her stalwart resistance on Lake Toran sapped the bandit and pirate forces of Geil Rugner who were dispatched from the Floating Fortress of Shasarazade to deal with her.
Kilauea was the only one of the generals to verbally object to Leon Silverberg's idea for the Kalekka Incident. She slapped the strategist before storming out of the meeting. Several years later, she would die in an unexpected accident and her daughter, Sonya, succeed her position. Kilauea and Sonya were said to similar in appearance.
