Momoka features across the Hamatora franchise, appearing in *Hamatora: The Animation*, *Re:_Hamatora*, the recap film *Fw:Hamatora*, and the spin-off *Mini Hamatora: Minimum Hamatora*.

She drives the core narrative by publicly exposing confidential details regarding Facultas Academy and the identities of Minimum Holders. This leak sparked widespread societal upheaval, fueling hostility from non-Minimum Holders towards Minimum Holders and provoking retaliatory actions from Minimum Holders asserting their right to exist. Her revelation intensifies the central conflict over Minimum abilities and their societal standing.

The spin-off *Mini Hamatora: Minimum Hamatora*, which reimagines the characters in an academy setting, features Momoka among the cast.
