In the electrifying chaos of the Storm Kingdom’s throne room

In the electrifying chaos of the Storm Kingdom’s throne room, Voltex seizes the moment. His long black hair flows wildly, caught in the fierce winds swirling around him. With unwavering focus, he charges towards the towering Lightning Demon, whose chest glows ominously with a pulsating gem, the source of its immense power. Voltex’s dark sword, imbued with the golden energy of his "Shadow Eclipse" technique, gleams with an intense, otherworldly light. As he closes in on the demon, the golden energy around his blade intensifies, crackling with power. With a swift and decisive strike, he plunges the sword deep into the demon’s chest, piercing through the glowing gem. The moment the blade makes contact, a blinding flash of light erupts from the impact, sending arcs of electricity coursing through the air. The Lightning Demon lets out a deafening roar as the energy within it destabilizes, its massive form beginning to crack and splinter from the force of the blow. The gem shatters under the might of Voltex's attack, its pieces scattering into the air like shards of light. Seraphina, her red hair and robes billowing in the tempest, stands ready to support, her magic still holding the winds at bay as Voltex delivers the final blow. The scene captures the climactic moment of their battle, with Voltex’s long hair and flowing coat adding to the dramatic intensity of the scene, as the once-unstoppable Lightning Demon begins to disintegrate, its power broken by the strike to its heart.
