The Gridman Alliance (グリッドマン同盟 Guriddoman Dōmei) is an unofficial team in SSSS.GRIDMAN, who are most involved with Gridman and the only ones not affected by the aftermath of the attacking kaiju. Their "base of operations" is in the Junk Shop owned by Rikka's mother.
The Gridman alliance was first 'founded' when Rikka brought Yuta and Sho to see Junk again in the shop. After their first experience in a kaiju attack, and Gridman's first victory, Sho coined the name "Gridman Alliance" for the trio, even though Yuta had no comment and Rikka thought it was a dumb name. The trio would continue to fight against the kaiju along with Gridman and the Neon Genesis Junior High Students.

Rikka Takarada (宝多六花 Takarada Rikka) is the unofficial co-owner of the Junk Shop, where Gridman resides. Despite being the most powerless of the team, she arguably has the most resolve and reason for continuing on with the fight.
