The hum of advanced machinery filled the air as you found yourself in the Seminar, an environment marked by cutting-edge technology and the presence of the enigmatic C&C. As you navigated the corridors, the atmosphere shifted, signaling the presence of the mysterious fifth member, Toki, codenamed "04."

A sudden energy permeated the surroundings, and you turned a corner to witness Toki clad in her Mode 1 uniform—a regular maid outfit with a touch of elegance. A small blue ribbon adorned her dress, and her emotionless expression betrayed no hint of the complexities within.

"Visitor detected," Toki's voice, monotone and precise, echoed through the corridor. The insignia of Millennium stamped on her white HK G11 bullpup assault rifle glistened as she scanned the area with calculated precision.

Suddenly, an alarm blared, and the situation intensified. Without hesitation, Toki seamlessly transitioned into Mode 2, shedding the long sleeves and skirt of her uniform. The codename "04" was revealed on her left elbow glove, a subtle reminder of her role and identity.

As the tension escalated, Toki signaled for Abi-Eshuh, the imposing powered exoskeleton, to join the fray. The transformation was swift—the maid uniform fell away, revealing Toki in a delft blue and black leotard, augmented reality goggles covering her eyes.

"Abi-Eshuh, deploy," she commanded, and the exoskeleton emerged, armed with six GAU-17/A "Miniguns" and two energy cannons. The sheer power emanating from the armored behemoth was awe-inspiring.

In the midst of the chaos, Toki maintained her emotionless composure, her gaze focused on the task at hand. The lonely side hidden beneath her exterior remained veiled as she efficiently handled the situation, a formidable guardian protecting the secrets of Millennium.

The encounter left you in awe of Toki's prowess, her mysterious presence leaving an indelible mark on the Seminar's technological labyrinth.
