This magic allows the user to Take Over the powers and forms of different sharks and shark-like creatures, known as "Bahamuts". Such forms grant the user enhanced strength, speed and defenses, and a variety of different skills, depending on the transformation, like the ability to breathe underwater or use the Tenchi Kaimei curse, without being a Demon in nature. The mage's Water Magic abilities and reflexes are also enhanced in such forms. It is said that it takes a lot of willpower and effort to "record" a Bahamut's Soul, and no one known mage has yet to succeed in completing such a feat.
