About にじさんじ公式
PARALLEL CASE: 2434 is an interactive story project created in collaboration between NIJISANJI and Fourth Boundary, scheduled to launch in summer 2026. It invites participants into a mysterious narrative in which unexplained events affecting NIJISANJI livers begin to cross into the real world. The experience unfolds through BPS, a system that connects users with the story’s parallel world, and D4-Bird, that world’s social network.
Players investigate posts, real websites, and, at times, physical items delivered to them, gathering clues to help resolve the cases. BPS also lets users save investigation records and check their progress after creating an account and logging in. The project brings together NIJISANJI, a VTuber and virtual-liver initiative whose talent activities include video streaming, events, merchandise, digital content, and music, and Fourth Boundary, a creative group specializing in alternate reality games that blend fiction with everyday life.
Together, they offer a story experience designed to blur the boundary between virtual and real
