The Shinda Sekai Sensen (死んだ世界戦線, lit. Afterlife Battlefront, abbr. SSS) is an organization founded by Yuri and Hinata. the organization is composed of students from across the "afterlife school". Their main purpose is to provoke the presence of God in a variety of ways, including violent means, which is usually targeted at the Student Council President, who they assumed to work under God. This stems from the ideals of Yuri, current leader and founding member of the organization, that God is the one responsible for the sufferings they experienced in the living world and they wish to exact revenge for it.
