Chapter 1: A Fateful Encounter
Delta Takeshi had been living an ordinary life in this new world, though his extraordinary past weighed heavily on him. He had been the ruler of time and space, capable of controlling the very fabric of reality itself. Now, reincarnated as a mere human, he wandered aimlessly through forests and dungeons, seeking solace from his eternal boredom.
On one of these excursions, while walking through the forest, he encountered a girl unlike any he had ever seen. She was lost, vulnerable, and on the brink of being attacked by an Astral spirit. Her striking features—long, flowing white hair, piercing blue eyes, and an innocence that radiated from her every pore—captured his attention instantly. But then he saw that a astral spirit was trying to attack her then Before the spirit could harm her, Delta, without a second thought, intervened. His voice echoed through the forest, freezing time itself. "Freeze," he commanded, and the Astral spirit halted mid-action, as if trapped in a moment outside of time. With a simple command, "Erase," Delta wiped the spirit from existence, not even leaving a trace behind.
The girl, Riesellia Miyamoto, stood there in shock, unable to comprehend what had just transpired. Her voice trembled as she introduced herself, "I... I'm Riesellia. Riesellia Miyamoto."
Delta gave a warm smile, offering his hand. "I'm Delta. Delta Takeshi."
Her face softened with a slight blush. "What a cool name..."
The two stood in an awkward silence for a moment, until Riesellia collapsed from exhaustion, the stress of the day overwhelming her. The rain began to fall in soft sheets, and Delta, without hesitation, scooped her up into his arms and carried her to his home.
When they arrived, Delta noticed the absence of his usual housemates. Siesta, his sister, had gone to the Royal Capital for the day. The house was quiet—too quiet.
Delta laid Riesellia in his bed, then went to prepare some rice porridge to help with her fever. When she awoke, Riesellia was disoriented and confused, finding herself in an unfamiliar room. Delta explained everything calmly and reassuringly. "You're safe here. You were exhausted, so I brought you home to rest."
Delta then fed her the porridge he had prepared, despite Riesellia's embarrassment at being cared for in such an intimate way. She hid her face in the blankets, cheeks flushed from both gratitude and the awkwardness of the situation.
Later, when Siesta returned, the situation took an unexpected turn. Siesta, upon seeing an unfamiliar girl in her brother's bed, immediately assumed the worst. A storm of jealousy and confusion stirred within her. The two girls, in that moment, were on the verge of a confrontation, but Delta quickly intervened and explained everything. The misunderstanding was cleared up, though it was clear that the dynamic in the house had irrevocably changed.
Riesellia, tearfully recounting her tragic past, revealed that her parents had abused and abandoned her, calling her an unwanted child. Her story resonated deeply with Siesta, who softened toward the girl. Though the jealousy was still present, Siesta couldn't help but pity Riesellia's plight. She would soon find herself drawn to the girl, even though her feelings for Delta were growing increasingly complicated.
Riesellia, for her part, was overjoyed to be taken in. She had been cast aside by her own family, left to wander the wilderness alone. Now, she found herself in a home where she was treated with kindness and care. There was, however, one more secret weighing heavily on her heart. She had fallen in love with the man who had saved her—Delta Takeshi.

Chapter 2: The Tension Between Us
As the days passed, Riesellia settled into life with Delta and Siesta. She began to cook meals for them, seeing it as a way to express her gratitude. She cared for Delta with a tenderness that made Siesta's jealousy flare even more.
One morning, Siesta, seeing that Riesellia had gone to wake Delta up for breakfast, couldn't hide her frustration. She had always been the one to care for her brother, but now another girl had taken over her role. The quiet, simmering anger inside her made Siesta feel possessive in ways she hadn't felt before.
At breakfast, Siesta, with a sly smile, asked if she could feed Delta. Her voice was light, but her intentions were clear. After a moment of hesitation, Delta agreed, though his face reddened from the awkwardness. The situation felt strange, even for him. But to avoid hurting Siesta's feelings, he allowed her to feed him, though the act was not without its discomfort.
Later that day, Siesta suggested that they take a bath together, as they had when they were children. Delta was taken aback, unsure how to react, but agreed nonetheless. The atmosphere was lighter as they reminisced about their shared childhood—how they had always cared for one another and had spent countless hours together. It was a time before anything complicated had entered their lives.
Yet, in the midst of the playfulness, Siesta's feelings remained unresolved. She was beginning to realize that her attachment to Delta went beyond that of a sibling. She wasn't sure how to deal with this newfound emotion, but she couldn't deny it. As the night wore on, Siesta felt a strange comfort in reliving the old days, but her jealousy remained like a shadow, lingering just beneath the surface.
Meanwhile, Riesellia, quietly observing the growing tension between the two siblings, couldn't help but feel an odd sense of guilt. She knew that she had come between them, but her feelings for Delta were undeniable. She was too shy to confess, too unsure of her place in this tangled web of emotions.

Chapter 3: The Darkness Unleashed
The quiet tension that had built up between the trio came to a head one fateful morning. Delta awoke to an eerie silence in the house. There were no sounds of the usual morning bustle—no Siesta coming to wake him, no laughter from Riesellia as she prepared breakfast. The stillness was unsettling.
When he went downstairs, his heart sank. The house was a mess, torn apart as if it had been attacked. The atmosphere was thick with the presence of dark Mana—six distinct signatures, and two familiar ones—those of Siesta and Riesellia. Delta's blood ran cold.
Without wasting a second, he traced the Mana and teleported to their location. What he found was far worse than he could have imagined: Siesta and Riesellia were chained, bound and helpless in a cruel ritual meant to offer them as sacrifices to the Astral spirits.
A surge of rage erupted in Delta's chest. He broke the chains with his bare hands, his power overflowing in a wave of destructive energy. Without a word, he teleported the two girls back to the safety of his home.
"Who did this to them?" Delta's voice was low, a dangerous growl beneath his calm exterior.
The Astral spirits laughed cruelly, taunting him. Delta's eyes burned with fury as he demanded answers. When none came, he fought. His power was overwhelming, far beyond anything the spirits had expected. One by one, he obliterated them, until only the Astral God remained.
The Astral God, an entity of immense power, floated before him, her voice echoing in disbelief. "You… You're just a human. How can you have such power?"
Delta's gaze was cold. "I have the power to erase whatever I wish. Your kind was a nuisance to my world, and now you are gone."
The Astral God's eyes widened in shock. "No… You're lying. You have no Mana."
Delta smirked. "Oh, I have Mana. I just choose not to use it, because it's too destructive."
Without a second thought, Delta teleported them both to the vast emptiness of space. Before the Astral God could even react, Delta demonstrated a fraction of his power, collapsing two stars into one, creating a black hole. He reversed the process, restoring the stars to their original form.
The Astral God was left in utter shock, her mind shattered by the unimaginable display of power. "Who are you?" she whispered, her voice trembling.
Delta, unimpressed, simply replied, "I am the one who decides what lives and what dies."
The Astral God, stripped of her divine memories and reduced to a mere child, began to cry. Her transformation was so complete that she no longer remembered her true identity. Delta, his heart softening despite the brutal display of power, decided to take her with him.
