At first, she wanted to destroy Earth due to its civilization being at far lower level than hers, but begins to rethink her plan after stopping by a café and encounters a cat, a creature that is "too cute" and could not be found on any other planet in the universe.

[7] Four voiced comic videos were released on Jump Square's official YouTube channel between July and October 2021 to promote the series, featuring Yumiri Hanamori as Liza Luna.

[18] The series is directed by Jun Hatori, with scripts written by Aya Satsuki, character designs handled by Mayumi Watanabe, music composed by Shun Narita and Yūsuke Seo, and Yumiri Hanamori respiring her role as Liza Luna.

Rebecca Silverman was positive towards Liza Luna during her adventures on Earth but was critical of the art not displaying her "intense cuteness" properly and the plot lacking enough substance to fill the half-hour runtime, saying "This really would have worked better as half-length episodes because the good moments get lost in the drawn-out nature of the whole."

[28] She commended the show for capturing the "joys and anxieties of being a pet parent" but criticized the lackluster art and animation, overdone jokes and the story being unable to keep viewers past the three-quarters mark of its full-length run, concluding that "if you can get past the lackluster visuals and discombobulated start, Too Cute Crisis confirms what many of us already know: that pets truly may save the world.
