Shirō's body ached, the cold stone beneath her offering no comfort. Her wrists were bound, the chains clinking softly with her slightest movement. Across from her, seated on a simple wooden bench, was Kuzuki-sensei, his posture as rigid and composed as ever. Caster was elsewhere, her presence a lingering threat in the dimly lit chamber.
"Kuzuki-sensei," Shirō began, her voice strained, "why are you doing this? I always believed you were a good person."
Kuzuki's gaze remained steady, his expression unreadable. "I have my reasons," he replied calmly. "However, I have no interest in the Grail."
A flicker of hope ignited within Shirō. Perhaps he was unaware of Caster's methods. "Do you know that Caster is killing people to gather mana?" she asked cautiously.
To her initial relief, Kuzuki responded, "I was not aware." But his next words extinguished that hope. "However, I do not concern myself with the fate of strangers."
Shirō's heart sank. "Then why are you doing this?"
Kuzuki's eyes seemed to look past her, as if recalling distant memories. "Before I met Caster, my life was devoid of meaning. I was an assassin, trained to kill, but after completing my mission, I felt only emptiness. Becoming a teacher was an attempt to find purpose, but it was merely a facade."
He paused, his gaze focusing on Shirō. "Meeting Caster changed that. For the first time, I felt something stir within me. She asked for my help, and I chose to assist her, not because of the Holy Grail War, but because she gave me a sense of purpose."
Shirō listened, a mix of confusion and understanding washing over her. Kuzuki continued, "I do not seek the Grail. My actions are driven by a desire to support Caster, to find meaning in a life that was once hollow."
The room fell silent, the weight of his words settling between them. Shirō realized that Kuzuki's motivations were complex, rooted in a search for purpose and connection, even if it led him down a dark path.
As the torchlight flickered, casting dancing shadows on the walls, Shirō couldn't help but feel a pang of empathy for her teacher, a man who had found meaning in the most unexpected of places.
