Lightning Demon Slayer Magic is a type of Magic that grants the user various characteristics typical of a lightning demon: the ability to generate lightning from anywhere on his body, skin impervious to lightning and other traits. Lightning Devil Slayer Magic allows the user to produce and control lightning from any part of their body, which can be used both in melee and as a ranged form of offense. Lighting incorporated in this type of magic is of incredibly high voltages, being particularly destructive. Its user can also consume external sources of electricity and lightning to restore their body and replenish their strength reserves. However, this won't work for lightning they produced themselves.

Katuko Sukika's Spells
Name Description Appearance
Lightning Demon's Roar(雷鬼の咆哮Raioni no Hōkō)

Katuko generates lightning in his mouth and releases it in a concentrated, destructive blast, capable of destroying everything in a wide area in front of him. Unlike most other slayer he can create the lightning from his mouth and gather it in the form of a sphere instead of releasing it as a blast. He can then carry the lightning ball in his hands and fire the blast from his hands before the lightning dissipates. The special effect of this attack is that, even if the target survive, the lightning paralyzes them, preventing them from escaping subsequent attacks.

Lightning Demon's Sting(雷鬼の剣 Raioni no Ken)

Katuko generates lightning around his extended hand and concentrates it to such high levels that the lightning itself acts like a highly sharp blade, capable of cutting through almost anything. He can use this move to stab person or even use it to block blades, using it like a katana or a kunai. Even if his opponent is not badly injured by this attack, he or she will be stung by the lightning which will at the very least numb the attacked region and could even paralyze the target.

Lightning Demon's Speed(雷鬼の速 Raioni no Haya)

A spell that could be seen as a specialized application of Lightning Body, this involves Katuko momentarily turning his entire body into pure lightning and traversing short distances at speeds only possible for a lightning demon. Though slower than actual teleportation, Katuko sees this move as the next best thing. His most favored way of using this spell is to initiate a physical attack at a distance from his target and then using this spell to suddenly appear next to his target to have the attack land on his target.

Lightning Demon's Spear(雷鬼の槍 Raioni no Yari)

Katuko gathers lightning in his hand and creates a high concentration of electricity which he then releases in the form of an lightning spear extending from his hand. By concentrating the electricity into a spear like shape, Kenshin ensures that the charge does not dissipate out too much as that would reduce the attack's potency. It also means that the concentrated charge is strong enough to heat the air surround the edges to high enough temperatures to create a very thin layer of plasma which can cut objects on contact. Thus the entire length of the spear acts like a blade. This attack maintains a sustained flow of lightning which is maintained in the shape of a spear for as long as Kenshin continues the spell.

Katuko in Demon Force.

Demon Force: When pushed to the brink of death by Scarlet during a particularly gruesome training session, Katuko was able to achieve Demon Force. This Magic is said to be the final and most powerful state a Demon Slayer can attain in which the user's body turns into that of a demon. Katuko's Magic Aura becomes visible and his powers increase tremendously, receiving a large boost in terms of strength, endurance, resistance and power. In this state his entire body turns into lightning, so after activating Demon Mode he is virtually immune to physical harm. He can allow any attack to simply pass through them or simply absorb the attack. His hair grows in length and random bursts of lightning start forming in the air all around him. His fingers lengthen slightly and his fingernails grow till his hands resemble claws. The only time he achieved this state was accompanied by one of his manic episodes and his personality became exceedingly violent and lecherous.
