Shattered Reflections

As Percy continued to explore the depths of his newfound cursed technique, Ephemeral Tides, the thin line between illusion and reality began to blur. The training sessions became increasingly intense, with Percy pushing the boundaries of his powers under Sukuna's watchful eye.

One evening, the tranquil training ground transformed into a tumultuous seascape, courtesy of Percy's illusions. Aqueous Mirage conjured phantom enemies that seemed all too real, testing Percy's ability to control the deceptions he wove. Lingering Echoes heightened the psychological impact, leaving traces of imaginary sensations that lingered in the air like haunting memories.

However, the true challenge arose with Tidal Veil. Percy, shrouded in the intangible cloak of illusion, struggled to maintain a clear distinction between his own reality and the illusions he projected. The strain on his mental state became palpable, and Sukuna, sensing the turmoil within his stepson, intervened.

"Percy," Sukuna spoke with a tone of concern, "power without control is a double-edged sword. To master Ephemeral Tides, you must find the balance between illusion and truth, lest you lose yourself in the chaos you create."

In the subsequent days, Sukuna guided Percy through a series of mental exercises and meditation techniques. The training aimed not only to enhance Percy's control over his cursed technique but also to strengthen his resilience against the mental toll it exacted.

Deceptive Currents, with its illusions of treacherous terrain and unpredictable attacks, forced Percy to confront the disorienting nature of his own powers. The training ground became a battleground of shifting landscapes, challenging Percy to adapt and strategize within the illusions he himself had crafted.

Oceanic Hallucination, the most potent aspect of Ephemeral Tides, proved to be the ultimate test. Percy, with a heavy heart, induced vivid hallucinations in his mind, facing his own fears and desires related to the sea. Sukuna watched as Percy grappled with the nightmarish visions, a testament to the emotional resilience required to wield such power.

As the chapter drew to a close, Percy emerged from the training ground, both physically and mentally exhausted. The illusions that once danced around him dissipated, revealing a young demigod grappling with the complexities of his own abilities. The bond between Sukuna and Percy, forged in the crucible of training and shared challenges, deepened further. The tale of "Bonds of Olympus" continued, promising revelations and trials that would shape the destiny of gods and demigods alike.
