Exclusive Skills
Rikiya
-Shadow Cannon; one of Rikiya's strongest abilities, where he charges up his Shadow Magic for a significant amount of time in order to unleash a beam of energy against his opponents. While it's rather strong, it leaves him recoiling and open to attacks for a short window of time after he uses it.
-Flash-Step; taught by Swift, this is a skill where Rikiya uses his Wind Magic to give himself enough of a speed boost to basically bypass solid walls as if he had teleported. While it can be useful in tight situations, and he can use it regardless of whether he was previously in motion or not, it can be a very taxing skill, and failing to properly execute it would likely cause a lot of damage to him.
-Shadow Net; using his Shadow Magic, Rikiya prevents his opponents by moving by draping a thick, heavy net of shadow blobs overtop of them. It can be cut through, frozen or burnt off, but it's fairly tough and hard to move in due to its goopy property.
Kage
-Speedy Dodge (akin to BRS); incorporates flips and sweeps. Due to how fast Kage reacts, this can give him a notable edge; especially on the way back down. A Heel Smash is often used, although an Icicle Slash isn't uncommon with this.
-Icicle Slash; includes ice (for example, if sent flying in the air, using a combo of his katana and ice powers, he can do a spinning freeze slash similar to Chilly from Kirby SSU's air attack) in the dual-wielding/single-wielding attacks. Works best with single style.
-Shadow Dodge; since the Shade World of Ceres changes the properties of the character (and their perspective of the world), he dodges any physical attack due to solid forms not appearing in the Shade Realm. Strong enough magic will follow him regardless.
Mikage
-Sweep Break; with or without spiked leg armor, Mikage can sweep an opponent in a way that allows him to either break-dance-jump to his feet or to do a flip while aiming with the heel for a vital spot (not recommended).
-Reverse Steel; Heel crush with a twist; if he misses, or the opponent dodges, Mikage will spin in the air to either do a Hurricane Kick or a Tonfa Stab move (depends on the range).
-Shadow Lock; able to lock an opponent in place with shadows at their feet. He can use his Ice magic as well, but as it's his weaker element, it's less likely to work.
Shuyri
-Wave Strike; basically a Shoryuken, but with steel gauntlets or the sharp bone Shuyri can sprout.
-Jurassic Blow; a Megaton punch that either follows or precedes a sweep. May be followed or preceded with hasty kicks and jabs.
-Blood Split; basically spraying blood that serves to injure or blind the opponent.
Yoru
-Dark Lock; the ability to immobilize an opponent's limbs by blinding/binding them with darkness.
-Sword Lock; the groove in his gunblade makes it possible to block an attack, lock a weapon with it (especially if the edge of the weapon is hooked) and disarm the opponent, whether by a toss or a grab.
-Tower Strike; a way to throw an opponent away (while breaking a few ribs) by focusing power in the gunblade and swinging with great might (bullets are optional).
Extra Skills
-Capoeira Break; incorporates flips, sweeps, punches, kicks and slashes at the opponent rapidly and in a constantly changing direction. Characters like Mikage and Kagetora do this a lot.
-Sneak Attack; either with Darkness or Shadows, a character can hide themselves in either darkness, shadow or the Shade Realm to do a surprise strike against the opponent. Characters like Ryoku, Yoru and Kage do this commonly.
-Speed Burst; using the strength in their legs to bolster the speed, a character can reach insanely fast speed to torpedo through an opponent with a weapon. Characters like Etheram, Rouge and Kage do this a lot.
Abilities:
Kage:
Phoenix Flurry: With borrowed powers from his first Split, Kaze, Kage uses the power of Wind and Ice magic to summon a powerful blizzard that's certain to lock opponents in place (at least for a little while). If the hail and snow doesn't hurt the target, the biting wind certainly will!
Fury Blitz: Rapid slashes are aimed towards the opponent; it isn't limited to just swords, either. Claws, kicks, sweeps--if the speed of the attack doesn't serve to lock the opponent into place, at least it will confuse them!
Shadow Slash: Utilizing the power of Shadow Magic, Kage administers deadly poisonous cuts to the opponent's body; whether it corrupts them or not is entirely up to the foe's Elemental Advantages.
Pyro Link: With borrowed powers from the second Split, Kira, Kage has the ability to briefly use the Red Ice ability, which equates to ice bombs filled with highly explosive Flame magic. It also enables him to link attacks with demons of the Flame Affinity, although he isn't any stronger against Flame attacks.
Power-Kick Combo: Using a mixture of martial arts, speed and dirty fighting tactics (such as sweeping) Kage hits hard and fast with this ability, although it leaves him open for a brief moment, as it requires a lot of energy to execute.
Scorching Glacier: Ice so cold it burns the victim to the point of "Phantom Pains". Guard ability; only possible when Azuka is junctioned to his body.
Yoru:
Burning Flare: Channeling his magic into whatever weapon he's carrying (preferably lances for this particular skill), Yoru attacks swiftly and harshly, burning the opponent in vital areas in order to lend himself a slight advantage in mobility.
Dark Windmill: Utilizing Dark magic and a lance (or two), Yoru does his best to lock an opponent into place with this ability, not hesitant about attacking the opponents limbs (legs in particular) while doing so.
Scorching Somersault: Exactly as it sounds, and just as difficult to picture as it is to execute.
Light Link: Allows Yoru to (very briefly) create Shadow Magic with a demon that has a Mastery over Light magic. It doesn't lessen any damage he'd take from a Light Magic attack, but it is useful if he and another need to stop a foe in its tracks fast.
Miracle Phoenix: Allows Yoru to save himself from certain defeat by fashioning a heavy shield out of cinders, darkness and his gunblade as the last barrier. It's a very taxing ability, however; once Yoru uses it, his ability to use Flame Magic is nullified until he recovers. Only to be used in as a last-ditch attempt to save himself.
Dark Typhoon: Using the power of Wind and Dark magic (the former which needs to be supplied) Yoru locks the opponent into a hurricane of sharp winds, preventing them from moving by smothering them with dark tendrils to ensure maximum damage.
Kurogane:
Mirage Bomb: Similar to the Red Ice spell, Kurogane uses the explosive magic to singe the opponent to death; in the rare event that the opponent lives, the severe heat from the attack would leave them at least partially melted. An ability Kurogane is incredibly reluctant to use for obvious reasons.
Mystic Touch: The ability to heal any demon with Light, Dark, Shadow, Water, Flame or Ice magic, although it's very limited in what kind of injuries it can heal.
Shadow Spawn: The ability to split some of his power into copies of himself. Can be used for combative purposes, but is usually used for distraction tactics. The only drawback is the potential for Power Drain to take hold; this is why Kurogane very rarely uses this skill.
Space Link: The ability to use Space magic is rare, and while Kurogane can't master it, he can use a very small amount of this kind of magic. It's limited to Void magic, however, so unless Kurogane wants to spaghettify someone, he won't use this skill.
Hyper Psychic: With Reishiki's augmentive abilities, Kurogane can briefly use telekinesis and teleport if neccessary, although this Bond doesn't compensate for his weak mental defenses any. Useful if he wants to use Barrier magic as well, although it's very weak...
Serial Blow: With Thunder magic at his disposal (via absorption), Kurogane can mix his Heat/Kinetic Energy magic into this attack, destroying anything within radius that isn't protected by a barrier of some kind.
Phoenix Block: Although Kurogane is very mortal, for a limited time, he can use this skill to ignore any damage taken and enter an "Adrenaline Mode". Much like Lapis Lazuli and his Angel Curse spell, the user of this ability becomes completely paralyzed for a few months after the use of this attack, although unlike Angel's Curse, Phoenix Block does not cripple the user's magic capabilities.
Particle Cannon: Using Shadow, Light and Darkness magic, Kurogane can aim a concentrated blast of energy towards an opponent. It acts much like dynamite, although it does have healing capacities for Guardians who can absorb and withstand the attack. A cannon or blunderbuss is necessary to use this attack effectively, else "concentrated" becomes "shrapnel fire".
Rikiya:
Sun's Blessing: Using his powers as a Shadow Lord, Rikiya is able to bring out the true potential in his Shadow Magic and use it to heal his allies more effectively than his kind is usually able to do. As a result of leaning towards the Light half of Shadow Magic, this ability is further bolstered by his natural abilities.
Vocal Influence: Due to being the vessel for the Spirit of Greed, and thusly the host of Swift, Rikiya's gained the unique ability to influence others with his voice, whether it be through singing, yelling or otherwise. Considered his true power, this skill allows him to basically force others to do as he like if they fall victim to his compelling timber...though, the ability completely fails if the target is deaf.
Miracle Wish: As a result of reaching his full potential and containing more determination than any other known Youkai, Rikiya is able to influence others' fortunes and futures with his own powers, such that he can completely change one's fate through sheer determination and perseverance. While this means he's able to make others far happier and more fortunate, this does negatively affect his own luck to the point that he cannot change his own fate on his own, and his luck is similarly as horrendous as the luck he brings to others is incredible.
Species-Exclusive Skills
Junction - By attaching the energy one's body produces onto somebody else, a being (normally a Youkai) can become living armour that provides a status boost, access to the junctioner's elemental magic, and even immunities from elements they're strong against. However, in order to be able to do this, there has to be some sort of bond between the juntioned and the junctioner, whether it be a bond of trust or something much deeper. Depending on where the user junctions onto as well, the form of their specific armour, as well as the boosts they can give over will change as well. Those who are not fully Youkai or Youkai at all that do not have bodies of energy won't be able to utilize this skill fully, as they'll only be able to junction their spirit onto an ally (and thus will only give them the armour and boost portions unless they focus hard to give them access to their magic).
