Haruto Tsukishiro wakes up inside a vivid dream world where powerful beings known as Witches pull the strings of reality. Surviving this place means playing by its strange rules and solving its puzzles. Haruto teams with Katsumi Kanzaki, a practical research professor who studies these unusual phenomena, and Lily, a white haired girl whose mysteries deepen the stakes. Together they weave through shifting landscapes that fuse science, magic, and danger as they search for a way back to the real world. The more they learn about the witches, the more Haruto questions who he is and why this realm has chosen him. The plot centers on mind games rather than straightforward battles, inviting viewers to piece clues alongside the characters.

The show is an original concept created by Atsuhiro Tomioka and released in 2017. It features Nobunaga Shimazaki as Haruto Tsukishiro, with Takehito Koyasu, Kaori Nazuka, Ai Kakuma, and Aya Endo among the cast.

Critics described the series as brisk and stylish, pairing action and mystery with a sci fi sensibility. It invites questions about identity, reality, and the cost of escaping one's problems, while balancing fast pacing with a dreamlike atmosphere.

Among fans, 18if has a small but active online presence with discussions about its dream landscapes and the Witches. The striking visuals and voice performances left a mark on viewers who enjoy surreal fantasy anime.
