The sun had barely risen over the Demon Slayer Corps' headquarters, but Lyra was already awake. Her sword rested beside her as she waited, nerves and excitement mingling in her chest. Today, she would train with a Hashira—one of the legendary pillars of strength in this world.
Tanjiro approached, smiling. "You'll be training with the Flame Hashira today. He's strict, but he'll help you control your breathing and sharpen your instincts."
Lyra nodded, gripping her sword tighter. Control… yes, that's what I need.
Meeting the Flame Hashira
A tall man with blazing hair and eyes like molten gold approached. His presence radiated heat even in the cool morning air.
"Lyra, is it?" he said, his voice deep and commanding. "I've heard of your power. Impressive, but raw. Let's see if you can refine it."
Lyra bowed respectfully. "I'll do my best, sir."
He nodded once and then shouted, "Show me your Mythical Beast Breathing!"
Lyra inhaled deeply, feeling the magical energy within her respond to his scrutiny. She began with her basic form:
"Phoenix Strike!"
A wave of fiery energy surged from her blade, but it was uneven, flames flickering wildly. The Hashira's eyes narrowed.
"Your energy is strong, but uncontrolled. Power without focus is useless in battle."
The Training Begins
For hours, Lyra practiced under his watchful eye. The Hashira demonstrated advanced techniques, showing her how to channel her mythical energy with precision.
Dragon Tail Sweep: Now she could sweep wide areas without losing strength.
Kirin Charge: The lightning strike flowed smoothly, striking multiple targets with pinpoint accuracy.
Phoenix Strike: Flames no longer erupted unpredictably; they danced along her sword like living fire.
Each form became sharper, more elegant, and far deadlier. Sweat streamed down her face, but Lyra's determination never wavered.
A Test of Skill
Finally, the Hashira called forth a practice demon, a mid-level demon from the training grounds. Lyra's sword hummed as she took her stance.
"Mythical Beast… Dragon Tail Sweep!"
The demon lashed out, but Lyra's coordinated strike cut through its defenses effortlessly. Then, combining Phoenix Strike with a quick Kirin Charge, she sent the creature flying, landing safely in a heap.
The Hashira's eyes gleamed with approval. "Well done. You have power… but now, you have control. Remember, the stronger you become, the more responsibility you carry."
Lyra nodded, chest heaving, heart pounding. She finally felt it—the balance of magic, swordsmanship, and breathing.
A Shadow Looms
As she left the training grounds, a chill wind swept past. High above, a black figure watched from the treetops. Its presence was terrifying, unnatural, and familiar in a way that made her skin crawl.
Lyra's eyes narrowed. Another Upper Moon… I can feel it. And soon, we'll have to fight together… or not at all.
With her sword in hand and her new strength flowing through her, Lyra knew she was ready for whatever darkness came next.
