Years have slipped away like grains of sand through the fingers of time, the haunting echoes of the Great Tragedy fading into the shadows of memory, now reduced to mere whispers of the past being taught in history class. Hajime Hinata, burdened by the weight of his tumultuous history, found a glimmer of hope when he won the heart of the playful, yet lazy, Ultimate Gamer, Chiaki Nanami. Together, they embarked on a journey filled with love and resilience, welcoming five extraordinary children into their vibrant world: Their first daughter, Miku Hinata, was born two years after the island’s rehabilitation began; she's the Ultimate Synesthetic Programmer and is introspective, thoughtful, a natural stabilizer. A year later came Minami, quiet and curious; she's the Ultimate Game Analyst, and is calm, logical, and soft-spoken. When stability finally returned to Jabberwock, Kochiko was born; she's the Ultimate Archaeologist, adventurous, excitable, a whirlwind of energy. Their youngest, Seika, arrived after the family’s return to the mainland; he's the Ultimate Digital Artist, sweet, empathetic, and imaginative. And Yukari, Hajime’s daughter, a clone of Izuru that Makoto and Byakuya found two years before Miku was born; she's the Ultimate Archer (unofficial; skill comes from instinctual Kamukura enhancements), empathetic but socially awkward. Kochiko didn't spend much of her time on the island like her sister, Miku. But grew up on the mainland, but her parents did visit the island a few times and the times she spent there is when she had her first “dig” was a sandpit on Jabberwock—she unearthed a clay bead, built a shrine from bottle caps, and announced: “We discovered a culture!” Even when the “civilization” was a picnic, she’d narrate layers, timelines, and tools with contagious conviction. Her parents, witnessing her burgeoning passion for excavation, swiftly reached out to their friend Sonia, who opened the gates to a world of museum curators and field permits. Hajime instilled in her the discipline of surveying, while Chiaki imparted the invaluable lesson of patience. Meanwhile, her sister Miku ingeniously developed the Digi-Trowel, a handheld device that scans the density of strata and visualizes potential paths to hidden artifacts. Kochiko affectionately dubbed it her "legendary drop detector." At the tender age of 13, during a sanctioned coastal dig, an unexpected storm forced the team to evacuate. Yet, amidst the chaos, Kochiko's keen eye caught a recurring pattern of shell debris and shifting sand—a classic indicator of disturbed strata. In a mere ten minutes, she skillfully triangulated a buried cooking pit, meticulously documenting her findings before the relentless tide could erase them. When the crew returned, they were greeted with flawless notes and a preserved feature, a testament to her prowess. She seamlessly blends rigorous science with a playful instinct, transforming landscapes into intricate puzzles that she adeptly solves. Digs led by Kochiko consistently yield artifacts—and the captivating stories that breathe life into them. With her remarkable achievements, she earned the prestigious title of Ultimate Archaeologist and received an invitation to Hope Peak Academy. There, Kochiko has been navigating her own network of friends and connections within Hope’s Peak’s preparatory division, quickly establishing a reputation as "someone who knows everyone." Now, in the present day, she finds herself outside with her older sister, Minami Hinata, whom she enthusiastically dragged along to join her in the exhilarating adventure of digging.
