Yato's confident assertion echoed in the air, his demeanour unyielding. As the aftermath of the forbidden sword art's demonstration lingered, I couldn't help but feel a mix of awe and trepidation in the face of his raw power.
"But Master," I hesitated, "if you're the strongest, why bother with such a dangerous and forbidden sword art? What purpose does it serve?"
Yato's gaze bore into mine, his eyes reflecting both the weight of history and the determination of one who had faced the shadows. "Lucas, it's forbidden because this sword was linked to demons the sword art itself isn't dangerous but to learn this sword users must have an undying will if they can't have that they will never be able to learn it."
