The sea breeze, once a gentle caress, now felt like a taunt. Y/N opened her eyes to a world utterly alien, a deserted island beach stretching before her. No familiar faces, no signs of civilization, just the vast, indifferent ocean.

A primal scream ripped from her throat, a desperate cry against the unfairness of it all. "What is wrong with you, Senku?!" she shrieked, her voice swallowed by the endless expanse of water. Her hand instinctively went to her slightly rounded belly, a silent promise to the life within.

She was alone. Utterly, terrifyingly alone. As the sun began its slow descent, painting the sky in hues of orange and purple, Y/N knew she had no choice but to survive. But just as she began to formulate a plan, a blinding surge of green light erupted, tearing through the twilight sky. Her eyes widened in horror.

"Oh god, what now?" she whispered, crouching instinctively, shielding her unborn child as the world around her faded to an ominous, stony grey.
