A-Ko The Versus

Both of these older OVAs are sci-fi action comedies that revolve around a kidnapping plot. 

There was already a lot of similarities between The Choujo OVA and the Project A-ko movie, but in this sorta spin-off of A-ko the likeness is raised even higher thanks to the change of setting and dinamics, it's happening in a foreign planet and in space, much like in The Choujo, the protagonist is in a mission with her technological partner, kinda like in The Choujo, besides more things that were already familiar in the Project A-ko series and the both are plenty fun short OVAs.
