Abbot Toshiro Hakunetsu was the leading cleric of Mardük in Libaterra during the Yamatian Invasion and the Great War and acted as General Chouwa Kyouko's advisor. When Lutherin fell in the Reactor Core Explosion, he fled back to his homeland and witnessed the Cataclysm. He later ended up in Shipwreck Cove where he joined the Clergy of Tiamat as he no longer felt having any real purpose after Mardük's demise.
