Shuuten Kyoudan

With only 168 days until humanity's end, a mysterious cult called the Shuten Order rises from despair, orchestrating civilization's collapse. They establish their own nation state, Shuten, only for its Founder to be assassinated during the inaugural festival. The protagonist awakens amnesiac—two ethereal figures reveal she is the slain Founder, miraculously resurrected yet fatally incomplete. Her memories are gone, and she has mere days to live. To survive, she must uncover her murderer among the Shuten Order's five ministers and execute God's judgment. Racing against time under the alias Rei, she becomes an unlikely detective navigating a fractured city of secrets. With limited hours to investigate, every choice carries devastating consequences. Can she solve the mystery before her borrowed time expires?
