I became Hinagiku Kayo on a day

What if you woke up in the body of Hinagiku from Agents of the Four Seasons - with her memories, her grief, and the weight of a world that runs on the turning of seasons? A lone soul from our world gets just one day to walk in her shoes: to feel the quiet bond between Sakura and Hinagiku, to hold the Power of Spring in trembling hands, and to face enemies who see not an agent, but a chosen one blessed by the Goddess of Spring herself. This is a crossover story that blends the emotional core of Agents of the Four Seasons with an isekai twist. It's not about raw power - it's about carrying someone else's fate for a single day and discovering that even a moment of true understanding can change you forever.
