The private gaming sanctuary on the upper level of the factory felt calm and peaceful. Soft crystal lights glowed along the walls, and wide windows offered a clear view of the Petronas Twin Towers standing tall against the evening sky. Rimuru sat in the central hall, reviewing reports on the fiber network. The new technology had already connected every town and village, bringing knowledge and joy to all.
Veldora stood nearby, his posture steady and thoughtful. Diablo approached with flawless grace, his black butler uniform immaculate. He bowed deeply before Rimuru and Veldora, his crimson eyes filled with unwavering loyalty.
"My lord," Diablo said, voice smooth and respectful. "I have reflected on the growing strength of the federation. The new factory, the towers, the games, and the virtual worlds have brought much joy and power. Yet I believe we still need a force that can protect you in the shadows. I will travel to the Underworld to recruit worthy subordinates—powerful demons who will serve only you. I will return with them soon."
Rimuru looked at his loyal servant with quiet trust. "Diablo, you have always thought ahead for our safety. If you believe this is the right step, then go. Return safely. We will wait for you."
Veldora placed a steady hand on Diablo's shoulder, his golden eyes calm. "Takumi says your dedication is truly admirable. The Underworld is a vast and dangerous place, but your strength and loyalty will guide you. Bring back those who will serve with the same heart you do."
Diablo bowed once more, a faint, determined smile on his lips. "Thank you, my lord. I will not fail you."
He vanished in a swirl of dark energy, heading to the Underworld.
Days passed quietly in Tempest. The factory continued to hum with life as citizens tried the new PCs and VR rooms. Milim and Ramiris spent hours exploring virtual worlds, while Hakurou trained his mind and sword through Dota 2 matches. Gobta practiced his Super form on the training ground, and the fiber network carried news and laughter across the federation.
One evening, as the sun set behind the towers, a dark portal opened in the central hall of the sanctuary. Diablo stepped out, his presence as elegant as ever. Behind him walked three figures—high-ranking demons who carried an ancient, overwhelming aura.
The first was a beautiful woman with long white hair and cold, elegant features. She wore a refined dress that seemed to flow like mist. The second was a young girl with violet hair and playful yet dangerous eyes, dressed in a cute yet sharp outfit. The third was a tall, graceful woman with yellow hair and a calm, intelligent gaze, her clothing simple but powerful.
Diablo bowed deeply to Rimuru, who had gathered with Veldora, Milim, Ramiris, Shuna, and the others.
"My lord," Diablo said, voice filled with pride and loyalty. "I have returned from the Underworld. These are the Primordial demons I have chosen—Violet, White, and Yellow. They are among the strongest and most loyal. They have agreed to serve you with absolute devotion, just as I do."
The three demons knelt gracefully before Rimuru.
White spoke first, her voice cool and refined. "I am White. I offer my power and loyalty to you, Rimuru Tempest."
Violet smiled playfully, her eyes bright. "I am Violet. I will serve with all my heart and bring chaos to your enemies."
Yellow bowed with calm respect. "I am Yellow. My knowledge and strength are yours to command."
Rimuru looked at them with deep golden eyes full of gentle authority. He stepped forward and placed a hand on each of their shoulders in turn. "You have come far to serve. I accept your loyalty. From this day, you will have new names and true forms that match your strength."
He channeled his power, strengthened by the S cell and the bond with Veldora and Takumi. A warm light surrounded the three demons.
"White, you shall be Testarossa. Your elegance and power will shine like fresh snow."
"Violet, you shall be Ultima. Your playful spirit and deadly skill will bring joy and fear in equal measure."
"Yellow, you shall be Carrera. Your calm wisdom and overwhelming strength will guide and protect us all."
The light grew brighter. The demons' bodies transformed, becoming fully real and stable, no longer bound by their previous forms. Testarossa's white hair flowed like silk, Ultima's violet eyes sparkled with mischief, and Carrera's yellow hair gleamed with quiet power. They rose, their auras now perfectly controlled and loyal to Rimuru.
Testarossa smiled elegantly. "Thank you, my lord. The name feels right."
Ultima giggled with delight. "Ultima! I love it! I will serve you with all my chaos and fun!"
Carrera bowed with calm grace. "Carrera… it carries strength and wisdom. I am yours."
Milim clapped her hands with bright excitement. "They look so strong and pretty! Welcome to Tempest! We can play games together and fight side by side!"
Ramiris floated around them, adding fairy sparkles. "Your new bodies are beautiful! The VR rooms will feel even more fun with you here."
Shuna smiled softly. "I will prepare a special meal to celebrate your arrival. You are part of our family now."
Gobta grinned widely. "More strong friends! We can train together. Super Gobta and your powers will make us unstoppable!"
Benimaru nodded with sharp approval. "Their strength will strengthen our defenses. Welcome."
Diablo stood proudly beside them, his crimson eyes filled with satisfaction. "They will serve you well, my lord. I have chosen the best."
Veldora placed a steady hand on Rimuru's shoulder. "Takumi says this is a magnificent addition. The Primordial demons bring ancient power and new loyalty. Together with the technology and the bonds we share, Tempest will face any future with confidence."
Rimuru looked at the new arrivals with warm authority. "You are welcome here. Serve with the same heart as Diablo, and you will find a true home in Tempest. We grow stronger together."
The sanctuary filled with cheerful voices and shared warmth. The Primordial demons knelt once more, their loyalty now sealed with names and real bodies. The evening light from the towers cast a gentle glow over the hall, reminding everyone that new strength had arrived to protect the peace they had built.
Testarossa, Ultima, and Carrera rose and joined the group, their presence adding a new layer of power and elegance. The factory hummed softly below, the fiber network connected the federation, and the VR rooms waited for new adventures.
Rimuru smiled quietly. "Welcome to our family. Let us walk this path together."
The chapter of loyalty and new beginnings continued, bright and full of possibility, as Tempest's story reached even greater heights.
