Through a temporal portal that rippled like liquid glass, Eiji and Atsurai stepped into a dimension never before familiar to humanity—a place smelling of eternity and ancient dust.
Eiji found himself in the heart of a deep canyon, surrounded by colossal rocks carved by the winds of time. Golden sandstorms swirled on the horizon like sentinels guarding this abandoned wasteland.
Amidst this sandy turmoil stood a man as firm as a mountain. He wore simple, dark clothing bearing the marks of countless trials, and held a wooden staff that seemed to have witnessed the rise and fall of entire civilizations. The sand particles orbited him gently, as if obeying his silent command.
Atsurai: "Compose yourself, Eiji. This is the man who will forge you. He is a master of the ancient Pulse Energy and the Lord of Elemental Control."
The winds suddenly died down. A heavy silence fell as the Master's eyes landed on Eiji's face—specifically on the mark glowing in his right eye.
The Master (Internal Thought, shocked): "That mark! That face carrying the features of the departed... He is ..! The heir my eyes have never seen, now standing before me as a Guardian of Fate."
Eiji stepped forward hesitantly, feeling an inexplicable pull toward this man. He bowed with an innate sense of respect.
Eiji: "I am honored to meet you, Master. I am Shiragumo Eiji. I have come to learn what my heart remains ignorant of in this world."
The Master (Struggling to hide the tremor in his voice): "Very well, Eiji. We won't waste time on pleasantries. Pulse Energy is not merely physical strength; it is your existential rhythm in harmony with the cosmos. We shall begin decoding the temporal basics now."
The training commenced under a sun that never set. The Master watched Eiji's every move, teaching him how to merge Pulse Energy with every cell in his body and how to utilize "Temporal Sense" without burning out from the sheer pressure.
The Master: "When you use the 'Temporal Deceleration' spell, remember that you aren't trying to stop the entire universe. You are expelling time from a small field surrounding your opponent. Use the minimum energy to achieve the maximum effect."
Eiji lifted the Grimoire, feeling its weight increase with every new piece of information. The pages flipped rapidly before his eyes.
Eiji: "I feel the energy flow becoming smoother, but this book contains a hundred spells! How can a mortal master all this complexity?"
The Master: "Power lies in a deep understanding of the essence, not in numbers. Most are support spells, but you must set your sights on Spell 100: 'The Last Chronos.' It is your final sanctuary, but it is a double-edged sword that may swallow its wielder."
As Eiji trained, the Master taught him how to summon the latent sand power of the dimension, forming a shield called the "Desert Shroud."
The Master: "The power of sand lies in patience and the ability to crumble, then unite. It was the first element I chose in my youth, and it never fails those who understand its stillness."
Suddenly, the sky above the valley cracked with a crimson hue, as if a deep wound had been opened in the fabric of the universe. Distorted temporal screams echoed through the air.
Atsurai (Shouting a warning): "They're here! The Code Phantom has sent a new Echo, more malicious than the last!"
From the heart of the temporal rift descended a feminine entity cloaked in the black of night. It was **Lunaris**, a sorceress clad in a lunar outfit studded with the energy of extinguished stars. She held an aura of dark magic that absorbed the surrounding light.
Lunaris (In a bone-chilling cold voice): "Little Dimensional Guardian... I have come to put an end to this annoying rhythm and erase your existence from the records of eternity."
Eiji (With impulsive anger): "I'll face her alone! I won't let the Void pollute this place!"
The Master placed a heavy hand on Eiji's shoulder, firmly stopping him out of fear for his safety.
The Master: "Do not be reckless, my boy. This opponent far exceeds your current capabilities. We fight as a team... my grandson."
Eiji (In a shock that made his heart skip a beat): "Your grandson? What did you say?"
The Master: "No time for questions! The enemy is before us! Cast the Temporal Deceleration on her surroundings now! I will provide cover and defense!"
Eiji sprang into action, obeying the command. He unleashed a wave of temporal deceleration that made Lunaris's movements appear as though she were moving under the weight of a mountain, giving the Master an opening.
The Master summoned the entirety of the valley's sand, forming swirling sandstorms that blinded the sorceress and pressured her dark shield with immense force.
Lunaris (Growling): "Did you think sand would imprison the stars? Take this!"
Lunaris unleashed bolts of black magic, but Eiji used the "Phantom Mirage" spell from his book, moving like lightning to appear behind her and unleash a concentrated pulse of energy that struck her shoulder.
The Master: "Well done! But don't forget the balance! Use the Desert Shroud to protect yourself from her magic's recoil!"
The Master and Eiji retreated in a stunning harmony—Eiji representing speed and pulse, and the Master representing the solid sand shield. Lunaris was forced to retreat, vowing to make them vanish inside a temporal black hole.
After the sorceress vanished, Eiji fell to his knees, gasping. Atsurai approached and used the healing spell "Vital Pulse" to mend his minor wounds.
A long silence followed. The Master looked at Eiji with a gaze full of tenderness, regret, and a love suppressed for years.
The Master: "You haven't even asked me yet why I called you my grandson in the heat of battle."
Eiji (Voice choked with disbelief): "I was busy staying alive... but now I demand an answer! Why am I here? And what is the truth about my grandfather, whom everyone calls a disaster? The Ruler said he destroyed the universe. So, who are you?"
The Master (Sighing deeply, the wrinkles on his face telling a story of long pain, then placing his hand on his heart): "The Ruler told you only half the truth. He told you of the collapse, but he didn't tell you of the sacrifice."
The Master (With a direct, steady gaze): "Eiji... I am not just a passing teacher you met in a deserted valley... I am Kimiko Taiso, whom everyone thought was dead... I am your grandfather."
Eiji's eyes widened in total shock. The Eternal Mark in his eye ignited with a powerful flash, illuminating the area as if finally recognizing its original source.
