Kokkoku

When her nephew Makoto and brother Tsubasa are kidnapped, Juri Yukawa's family is given only thirty minutes to deliver the ransom. Her grandfather responds by revealing a secret he has kept for years: a stone capable of sending them into Stasis, a world where a single moment is frozen and almost everyone else stands motionless. They expect stopped time to give them an easy advantage in rescuing the captives, only to discover that other people can move there too and that mysterious beings enforce its rules. A desperate ransom attempt becomes a conflict trapped inside one suspended second, where waiting solves nothing and finding a way out may prove harder than entering.
