As the Null Order's agents advanced, the atmosphere in the room shifted, filling with tension. Kei, Teri, and Ignis braced themselves, standing firm despite being outnumbered. They exchanged a brief, wordless glance—a reminder of their unity, their purpose. This was what they had been training for, and they were ready.

Suddenly, Rylan and Selene burst into the room, followed by several other Echo Guardians. With swift precision, they took their positions alongside the trio, leveling the odds. Selene nodded at Kei, her eyes filled with determination.

"We've got your backs," Selene said, her voice steady. "Let's show them what we're made of."

The Null Order agents closed in, their movements synchronized and controlled. Kei took a deep breath, focusing her energy. With a swift motion, she released a wave of icy blue light from her hands, freezing several agents in their tracks. Teri was right beside her, his fiery wings spreading wide as he launched a barrage of flames, forcing more agents to retreat.

Ignis moved with agility, her white dress flowing around her as she dodged incoming attacks. She weaved through the crowd, delivering precise strikes that disabled agents without causing harm. The room had transformed into a battleground, filled with bursts of light and shadow as the two sides clashed.

From the sidelines, the Narrator's voice echoed in disapproval. "Fools," he sneered, his voice reverberating through the speakers. "You may resist, but you will only delay the inevitable."

Ignoring his taunts, Kei fought on, her icy powers flowing with newfound intensity. Beside her, Teri unleashed waves of fire that forced the agents to scatter, their numbers thinning. With each strike, they felt a surge of energy, as if the strength of those watching beyond the Fourth Wall was flowing into them, fueling their resistance.

Then, with a loud crack, the large screen shattered, and the Narrator's image disappeared. For a moment, the room was silent, save for the ragged breaths of the exhausted Null Order agents. The remaining agents, disoriented and demoralized, glanced at one another before fleeing the room.

As the last of them retreated, Selene and Rylan led the crowd of onlookers in applause, their cheers filling the room. The city's elite—who had watched the battle unfold with a mixture of fear and awe—now looked at the Echo Guardians with respect, perhaps even admiration.

Kei, Teri, and Ignis stood together, catching their breath. Despite the victory, they knew this was only a small battle in a much larger war. But tonight, they had struck a blow against the Null Order's influence, proving to the people of Echo City that resistance was possible.
