Rinne no Lagrange, Senki Zesshou Symphogear Recommendations
Crazy over-the-top action and heavy themes of friendship and hope.
Girls who have some sort of power that they use against an other-worldly enemy. Both shows have dark undertones, female protagonists who's goal in life is to help others, mecha/mecha-like devices, and sci fi mixed with slice of life comedy. Symphogear is focused on singing in suits that grant them powers while Rinne is focused on piloting mechas.
