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.
Operation meetings are held in the Anti-Angel Headquarters with traps set at the entrance to prevent Angel from intruding their meetings. The principal's office was their de facto meeting place since its foundation during the events of Heaven's Door manga.
There is no certain number of affiliated members of the organization, but it can be estimated to be a large amount, if the figures of its sub-divisions are also included.
- Yuri Nakamura (leader/founder)
- Hideki Hinata (co-founder)
- Yuzuru Otonashi
- Ayato Naoi
- Miyuki Irie
- Shiori Sekine
- Operation Principal Room Heist
- Operation Tornado
- Guild Descent Operation
- Angel's Assault Operation (/ Operation Angel Area Invasion)
- Operation Monster Stream
- Operation High Tension Syndrome
Although not directly affiliated with the SSS, these two sub-divisions act accordingly with Yuri's plans, assisting in most of the major operations of the organization.Iwasawa on vocals and rhythm, Hisako on lead guitar, Irie on drums, and Sekine on bass.
Their main purpose is to serve as a diversion for missions which require SSS to move without arousing suspicion from other students, particularly "Operation Tornado", which involves taking food coupons from NPCs for their reserves. Their songs are very famous with the students and the band uses this to help out while the rest of SSS covertly proceeds with their plans.
After Iwasawa's disappearance, Yui, the band's promotion assistant, assumes the role of vocals and rhythm guitarist.Chaa, the man who first introduced guns in the Afterlife world.
While Naoi and Takeyama aren't part of a sub-group they do not engage in combat and are both used to gain intelligence through hypnotism or hacking skills. Yusa is rarely seen in the field, preferrring to work alongside with Yuri as secretary and pair of eyes in the field.
- The motto of Shinda Sekai Sensen's coat of arms states, "rebels against the god".
- The three S's of the logo bear structural resemblance, if not reference, to the sig runes in the insignia of the paramilitary organization Schutzstaffel, which was under Adolf Hitler during World War 2.
- Yuri and Hinata were the first official members.
- In the first episode, they change the name of the battlefront (Originally "Like-Hell-I'm-Dead Battlefront"), but they agreed to change it back to the original name: Shinda Sekai Sensen.
- Before every operation, Yuri will announce once and loudly "Operation Start!"
- There is an ongoing joke that the members of the Shinda Sekai Sensen could never agree on an official name, and it was always changed (examples include the "Not Yet Dead Battlefront, "Desperate Battlefront", "Suicide Core Battlefront," the "Afterlife Battlefront," the "Almost Dead Battlefront", and the comical "Barnacle Battlefront").
