|Satan Soul: Halphas|
A Satan Soul form that allows the user to take over the appearance, abilities and powers of the demon Halphas. In such state, the users' ears are covered by sky long blue scales, extending backwards, and gain pointed edges, bearing resemblance to those of fictional elfs. Users also gain similar scale-like armor in their forearms and hands as well as in their legs. Each forearm also receives a fin-like protrusion on its outer side. They also grow a large, sky blue, stocky tail seemingly made of metal plates or scales, getting smaller and smaller near its end. The clothes also change, with any attire the user might be donning being replaced by a light blue and dark blue, one-piece suit revealing their arms and legs, which is open on the front and the back, exposing most of the belly, wide cleavage and upper back too. This Satan Soul form also dons two angel-like wings that are always pointing upwards.
Flight: In this form, through the use of a pair of wings that are reminiscent of an angel's, the user is capable of flight.
Enhanced Speed: While in this form, the user's speed increases dramatically, to the point where it can even surpass the speed of Satan Soul. In this form, the user's speed can even keep up with or surpass that of Racer.
Enhanced Durability: While employing this form, the user's durability is greatly increased, to the extent that it allows them to take a great number of hits by the enemy and still be able to fight. In this form, Mirajane Strauss was capable of enduring Racer's countless assaults, who has attained his maximum speed, and defeat him, while in her original form one of his attacks is enough to knock her unconscious.
Immense Strength: When employing this form, the user's strength is increased to the point where they can easily break through large amounts of solid rock with ease. While using this form, Mirajane Strauss is able to block a punch from her own Satan Soul form, that is being used by Mary Hughes, with one hand or even to create a crater, when throwing Racer to the ground, along with herself.
