Teams are formed through the Reaper Networking Service. Part of this process includes choosing a team name and a team leader. The team name can be changed at any time. A team's goal is to score more points than any of the other teams. Each team wins and loses as a group. When a team comes in first place, the team winner (or another member if they are not present) choses a prize for the whole team. If a team comes in last, the leader is erased along with the rest of the team. A team will also be entirely erased if the leader is erased by other means - the Variabeauties were erased when Plague Noise erased Kanon Tachibana.
Joining a team is not mandatory, however. In the case of Sho Minamimoto, he survived the Reapers' Game a numerous amount of times while not registered to any team. Reapers are also able to make teams and play the Game as is the case with the Ruinbringers, a team consisting entirely of Reapers.
There is seemingly no size limit to a team.

- Teams are only known to be used in Shinjuku's Reapers Game and are not present in Shibuya's rule set. However, teams were used in Shibuya when Shibuya adopted Shinjuku's rules.
- Both Sho Minamimto and Beat played aided the Wicked Twisters in the first week of NEO even though they were not officially registered to their team.
- Strangely enough, the battle fodder of Variabeauties, Purehearts, Deep Rivers Society consists solely of men, with no women being fought in battle. It is unclear if women exist on their teams, with the exception of Kanon.
