The dedicated training ground near the Petronas Twin Towers lay open beneath the clear morning sky. Soft grass stretched across the wide field, and the tall silver-blue towers stood like silent guardians in the distance. Rimuru stood at the center, his presence calm and steady. The Star Dust Breaker technique still echoed in the air from earlier practice, leaving faint trails of sparkling light that slowly faded.
Testarossa, Ultima, and Carrera stood in a line before him, their new bodies radiating controlled power. Testarossa's white hair flowed like fresh snow, her elegant posture radiating refined grace. Ultima's violet eyes sparkled with playful energy, her small frame hiding vast chaotic strength. Carrera's yellow hair gleamed with quiet wisdom, her tall figure calm yet imposing.
Diablo stood beside Rimuru, his black butler uniform immaculate. "My lord, they are ready. I have chosen them for their absolute loyalty and ancient power. Today they will train under your guidance to serve you perfectly."
Rimuru nodded with gentle authority. "Testarossa, Ultima, Carrera, your new forms are stable and strong. We will begin with basic integration of your abilities with the techniques we have developed. Show me your current strength, then we will refine it together."
Testarossa stepped forward first. She raised one hand, and a wave of white mist formed around her. The mist condensed into razor-sharp blades of ice that sliced through the air with elegant precision. "My power lies in absolute control and purity. I can freeze anything in an instant."
Ultima giggled and dashed forward, her body blurring with violet energy. She unleashed a storm of chaotic orbs that exploded in colorful bursts, each one carrying destructive force yet leaving the ground unharmed when she willed it. "My chaos is fun and deadly! I can twist reality itself if I focus."
Carrera remained calm and raised her hand. A yellow beam of concentrated energy shot forward, carving a clean line across the field before vanishing without a trace. "My strength is in focused destruction and wisdom. I calculate every strike to achieve the perfect result."
Rimuru watched with deep golden eyes full of quiet approval. "Your powers are impressive. Now we will blend them with the new techniques. Veldora and Takumi have prepared a way to link your abilities with the S cell potential and Star Dust Breaker. Begin with basic forms."
Veldora stepped forward, his mature voice steady. "Takumi suggests we start with controlled Super Saiyan-like bursts to increase your base power safely. Focus your will and let the S cell awaken the golden light within you."
The three demons closed their eyes. A soft golden aura began to glow around them. Testarossa's white hair gained golden highlights, her ice blades shimmering with new strength. Ultima's violet energy mixed with gold, creating chaotic yet beautiful patterns. Carrera's yellow beam intensified, now carrying the weight of starlight.
Milim landed nearby with a soft thud, her eyes wide with delight. "They look so strong! The golden light makes them shine like heroes from the games. Let me join the training—I want to see how their chaos mixes with my Dragon Nova!"
Ramiris floated above, sprinkling fairy sparkles. "The auras are pretty! I can add lights to make the training look like a festival. Try combining your beams with mine!"
Shuna watched from the side with gentle warmth, offering cool water and light snacks. "Your control is excellent. Take care not to push too hard at first. The new power needs time to settle in your hearts."
Gobta bounced on his toes, his own Super form faintly visible. "I trained my Super Kamehameha with Lord Veldora. You can do it too! Let us try a team beam together!"
Benimaru observed with sharp focus. "Their coordination is already natural. We can simulate real battles using the VR rooms later to test their integration."
Diablo stood proudly, his crimson eyes filled with satisfaction. "They learn quickly because their loyalty is absolute. My lord, their growth will serve you well."
The training continued with focused intensity. Testarossa combined her ice blades with a gentle Star Dust Breaker, creating a shimmering wave of frozen starlight that cut through the air without harm. Ultima mixed her chaos with golden energy, forming playful yet powerful explosions that lit the field like fireworks. Carrera focused her beam into a precise Star Dust Breaker, sending a clean line of starlight that pierced a distant target with perfect accuracy.
Rimuru guided each step with patient wisdom. "Feel the balance. The S cell gives you raw power, but your hearts keep it pure. Work together now—combine your strengths into one attack."
The three demons stood side by side. Testarossa created a base of white mist, Ultima added chaotic violet swirls, and Carrera channeled yellow energy into the center. They swept their hands forward together. "Star Dust Breaker!"
A massive, beautiful beam erupted—white, violet, and yellow light intertwined with golden sparkles. It roared across the field, bright yet controlled, and vanished into the sky without causing damage. The ground trembled lightly, and the twin towers shimmered in response, as if acknowledging the new power.
Milim cheered loudly. "That was huge and pretty! The colors mixed so well. You three are already strong together!"
Ramiris spun in delight. "The sparkles at the end were the best part! It felt like the night sky and a festival at the same time."
Shuna smiled softly. "The beam carried no anger, only purpose. Your hearts are truly aligned with Lord Rimuru's will."
Gobta raised his fist. "We can train as a big team now! Super Gobta, Star Dust Breaker, and all of you together—nothing can stop us!"
Veldora nodded with mature pride. "Takumi says their integration is flawless. The Primordial demons have adapted to the new power faster than expected because their loyalty runs deep."
Diablo bowed to Rimuru, his voice filled with quiet emotion. "My lord, they have grown in a single session. Their service to you will only deepen with time."
Rimuru looked at the three demons with warm authority. "You have done well. The Star Dust Breaker and the golden forms are now part of you. Continue training together. Your strength will protect the peace we have built and help us face whatever comes from the west."
Testarossa bowed elegantly. "We will not disappoint you, my lord."
Ultima giggled with playful energy. "This is fun! Training with everyone feels like a game, but the power is real. I cannot wait for the next session!"
Carrera bowed with calm wisdom. "Our power is yours. We will refine it until it serves you perfectly."
The group lingered on the field, sharing light snacks and gentle words. Milim suggested friendly sparring matches, Ramiris offered to add magical effects for future training, and Shuna made sure everyone stayed refreshed. Benimaru and Diablo discussed ways to incorporate the new techniques into federation defense. Gobta and Hakurou talked about joint sword and beam practice.
Rimuru felt a deep sense of peace as he watched. The Primordial demons had begun their training, and their growth strengthened the bonds that held Tempest together. The golden legacy and starlight had awakened new possibilities, reminding everyone that loyalty and friendship could turn ancient power into something warm and protective.
Veldora smiled quietly to himself. "Takumi says this is the perfect way to build our future. The shadows have found their light."
The training ground filled with cheerful voices and shared determination. Tempest's story continued, brighter and stronger than before, as new allies trained side by side under the open sky.
