Solar Devil Slayer Magic (Kasumi)

Solar Demon Slayer Magic is a powerful form of Demon Slayer Magic that was taught to Kira Nakano, the long lost sister of Itsuki and his siblings, by Helios. This magic transforms Kira into the embodiment of the dark sun and all that it represents, making it a very powerful and versatile magic.

Description
Solar Demon Slayer Magic is Kira's signature magic. It is a form of Caster Magic, Lost Magic, and Demon Slayer Magic that gives her the traits of the sun demon: Helios. When she was a baby Helios modified her magic origin with Magical Barrier Particles. These Magical Barrier Particles now work alongside her magic power to perform various effects. One such ability is the ability to transform her body into form that mimics Helios's demon form, turning her body into a very dangerous weapon. It also gives her absolute immunity to all elements relating to the sun. Furthermore, she is able consume these elements to rejuvenate her body, mind, and magic power. In addition, this magic creates a connection between Helios. This gives Helios the ability to attempt to possess Kira. Normally it would become easier with every use of the magic and would drive the mage to insanity. However, the powerful demonic genes that runs through her body passively rejects nearly every attempt Helios makes. This makes the side-effects of this magic a lot less dangerous and problemsome. The main ability of this magic is the ability to produce all aspects of the sun of the underworld from her body. The solar elements she is able to produce is a lot more dangerous. This because of the Magical Barrier Particles within the element and also because any person who touches Kira's element instantly gets radiation poisoning, making it very easy to die from it if an opponent underestimates her or is not careful. She has absolute dominance over solar energy, giving her the ability to use it for a lot of different purposes. As a form of Demon Slayer Magic, Solar Demon Slayer Magic is especially dangerous to demons. The elements produced by this magic are more than capable of harming or even some of the most powerful of demons. Just like the sun, she can use solar energy for nondestructive effects like healing herself or an ally or enhancing her own or an allies physical or mental abilities. This, however, takes a lot out of her so she rarely does it. In addition to being able to produce and control sun-based elements, she can transform her body in things related to the sun. Her mastery over the sun is said to be so great that night never falls in the area she is, trapping the area around her in a state of eternal day until she leaves.

Abilities

 * Sun Manipulation:
 * Dark Sun Manipulation:

Supplementary Spells

 * Sunny Day: Kira extends her hands toward the sky and increases the intensity and heat of the sun rays in the area around her for a brief moment. The sun ray's intensity and heat are increased so much that it blinds everyone in the general area while reducing everything to ashes. Kira has been shown to be able to use this on such a large scale that there seems to be nothing, but ashes for miles around.
 * Solar Transportation: Kira looks at a gathering of solar energy and channels her magic power throughout her body. This allows her to teleport to the location of the solar energy that she was focusing on.
 * Sun's Curse: This passively ability rather than a spell that causes anyone who touches her to be sun burned. The severity of the sun burn varies depending on the amount of force that was used to touch her. The severity of the sun burn increases every time the enemy touches her again. Since it isn't a spell, it doesn't require magic power, causing it to be constantly active.
 * Solar Recharge:

Basic Spells

 * Solar Demon's Fury:
 * Solar Demon's Brilliant Fist:
 * Solar Demon's Twin Suns:
 * Solar Demon's Landmine: Kira slams her hand against the ground flows her magic power into ground to create a large stigmata. When a target steps on the stigmata, the stigmata will releases a powerful surge of high-voltage lightning that can severely injure the foe as well as inflict terrible electrical burns.
 * Solar Demon's Marking: Upon physical contact, the user flows a bit of solar energy into the foes body. The solar energy will engrave an orange stigma onto the foe's skin. The stigma will constantly increase the opponent's body temperature at a very fast rate. So quickly in fact, the target might spontaneously combust after only five minutes. The only way to dispell the stigma is to overload it by channeling a large amount of magic power to it.
 * Solar Demon's Solar Storm: Kira extends one of her arms and releases a large and invisible cloud of electrons, ions, and atoms. Once released, the cloud spreads rapidly, negating any electric-based spell or ability in its path. This cloud is also able to throw a lightning mage's magic origin into disarray, preventing them from using any electric-based magic for extended periods of time.

Interimdate Spells

 * Solar Demon's Assault: Kira claps her hands together and causes a large stream of solar energy to burst up from the ground beneath the opponent, launching them into the air. The solar energy falls back to the ground to create a large pool of solar energy. Dozens of medium-sized bullets of solar energy are launched from the pool and at the opponent at high velocities. Each bullet is capable of hitting the opponent with incredible force while severely sun burning them. After all the bullets of solar energy have been launched, they gather above the opponent to form a large demonic looking creature that is made of solar energy. The creature launches itself at the opponent and brings them crashing to the ground with enough force to create large crater while sun burning the opponent even burn.
 * Solar Demon's Meteorite: This simple yet powerful spell allows Kira to a large meteorite of solar energy above the opponent. Once created, the meteorite comes crashing to the ground, resulting in a very large and fiery explosion that can reduce to ashes nearly anything in its path. Kira can also use this spell by gathering pre-existing solar energy above the opponent, allowing her to use less magic power.
 * Solar Demon's Thermal Detonator:
 * Solar Demon's Barrage: Using her incredible speed, Kira seemingly teleports to the opponent before kicking them high into the air as a stigma appears on the opponent's skin. Once the opponent is in the air, multiple spheres of solar energy are released from the stigma and begin to rotate around the opponent as they are suspended in the air. Kira teleports herself to one of the spheres and transforms her body into solar energy. Immediately afterwards, she launches herself from the sphere at blinding speeds and transforms back just in time to punch the target before turning back into solar energy and entering another sphere. This cycle repeats itself, causing the enemy to accumulate a lot of damage. Finally, after a minute Kira appears above the opponent and launches them to the ground with a solar energy-enhanced punch. This punch can severely injure the opponent and inflict a large third or fourth degree burn in the process.
