Unleashed Energy

As night fell, Aizen sought solace in a different pursuit. Experimenting with ambidextrous writing became his distraction, an attempt to divert his thoughts from the overwhelming reality. Mastering the skill surprisingly quickly, his grandfather, witnessing this anxious endeavor, grew concerned about the profound impact of introducing Aizen to the world of sorcerers.

The following day, Aizen's grandfather delved deeper into the intricacies of cursed techniques. He explained how the technique, engraved in a sorcerer's brain, determined 80% of their potential. A lesson on controlling emotions to harness cursed energy followed, accompanied by notes on proper energy manipulation. Determined, Aizen immersed himself in learning the techniques, understanding the basics but desiring more.

Eager to explore beyond the known boundaries, Aizen practiced containing the energy, recalling the limited manipulation seen in the anime. With his grandfather's encouragement, he removed the seals on his chest and neck. Unleashing the energy within, Aizen experienced an instant surge, prompting his grandfather to initiate a simple domain expansion.

As the world transformed into a realm of blackness with blades menacingly scattered, Aizen was tasked with controlling his energy swiftly. Despite his initial success, a sudden burst of green and blue emanated from him, and he lost consciousness.

From his grandfather's perspective, removing the seal on Aizen's neck unleashed a torrent of cursed energy, far surpassing his own. Anomalies in Aizen's existence traced back to his birth, coinciding with strange occurrences worldwide. Observing Aizen's control, the grandfather released a simple domain, only to witness it eroded from within. Aizen floated in the aftermath, surrounded by his own cursed energy. Approach brought an unsettling feeling, leading the grandfather to witness the decomposition of a thrown object. He cautiously waited, allowing the unsettling energy to settle.
