Set in a distant world on the verge of collapse, Ciel Nosurge follows the mysterious girl Ionasal as she attempts to recover her lost memories and communicate with a player from another dimension. Combining visual novel storytelling, life simulation elements and music-driven science fantasy worldbuilding, the game explores themes of connection, identity and reconstruction across worlds. Originally released episodically on PlayStation Vita, the story was expanded over multiple downloadable chapters and world packs.
