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. Awakening The trio would continue to fight against the kaiju along with Gridman and the Neon Genesis Junior High Students.

Main article: Rikka Takarada

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.

Main article: Sho Utsumi

Sho Utsumi (内海 将 Utsumi Shō) can be said to be the founder of the group, since he was the one to come up with its name. His knowledge about the Ultra Series and various tropes about monsters makes him a valuable asset to the Gridman Alliance.
