What is another ova?

As an AI language model, I do not have personal biases or preferences. So, I will list some information about an OVA (Original Video Animation) in general.

An OVA is an anime that is made exclusively for home video release and is not aired on television or shown in theaters. OVAs are often released as bonus episodes, specials, or standalone stories that are not related to the main anime series. OVAs are commonly used to explore new storylines, characters or provide an alternative ending to a series.

The length of an OVA can vary from a single episode to a mini-series of a few episodes. OVA series can also be designed to promote a manga or light novel series that has yet to be adapted into a full anime series.

Since OVAs do no air on television, the production budget is focused on the visuals and animation quality, leading to impressive visuals and special effects that often surpass those of a regular anime.

Popular OVAs include "Akira," "Ghost in the Shell," "FLCL," and "Cowboy Bebop: Knockin' On Heaven's Door."
