"Dimension Police" (ディメンジョンポリス Dimenjon Porisu) is a clan from the Star Gatenation, which has Imaginary Gift. This clan is themed around an interdimensional police force, as well as the villains and monsters they protect the universes from.
Dimension Police focus on having an immensely powerful Vanguard with high-powered and difficult-to-guard attacks. They have dangerous Vanguard effects that activate when they hit certain power thresholds, such as extra criticals or even a second Vanguard attack. In order to reach these power thresholds, Dimension Police rely on their rearguards to increase their Vanguard's power.
Dimension Police has the ForceImaginary Gift, which they can use to further increase the Vanguard's power.
