Giyuu Tomioka had long abandoned the notion of love. His heart, hardened by duty and regret, carried the weight of Shinobu Kocho's death-an event that shattered him beyond repair. She had been his light, but he failed to protect her. The guilt was a constant shadow in his life. Then, impossibly, fate gave him a second chance. Shinobu stood before him, alive, the same warmth in her eyes. The world seemed to pause, but as he faced her, one question remained: could he save her this time? Could he protect his butterfly, or would history repeat itself? credits to haiyunee for the cover art

Some of the major events happened in manga may be reversed in this fanfic book. And also, some spoilers from the manga may appear in here as well.

But how she would react that behind that cold personality of Giyu, he has that kind of personality that she wouldn't have expected.

"Giyuu-sama!" Aoi's voice broke through the tension, filled with relief as she hurried to Kanao's side, carefully cradling her. "The sun is almost up! We just need to...to..." Her words caught in her throat, her breath hitching as she looked up at Giyuu. He turned to face her, and what she saw made her blood run cold. Giyuu's eyes-once deep, round pools of blue that looked like a calm ocean-were now sharp, vertical slits, glowing with an unnatural light. Aoi's heart pounded in her chest, the realization crashing over her like a wave. The man who had fought so valiantly to protect them, who had refused to give in even when the odds were against him... was now one of them. "No..." she whispered, her voice trembling. "It can't be..." But the truth was undeniable. Giyuu was no longer human. He was a demon. ----- I finally protected someone." Giyuu thought, staring at the faces of Aoi Kanzaki, Kanao Tsuyuri, Kiyo, Naho, and Sumi. Sabito, Nee-san... are you proud of me?
