Overview
#

Agent Aika (also known as AIKa) is a unique blend of action and science fiction set in a world where a catastrophic earthquake has submerged Tokyo and much of the Earth. The story follows Aika, a professional salvager who dives into the watery ruins of the city to retrieve lost remains. The plot thickens when she takes on a high-stakes mission to locate the mysterious “Lagu,” only to find she has plenty of competition.

If you are looking to dive into this series, you can watch the anime on Prime Video to see Aika’s underwater adventures for yourself.

Is Agent Aika Finished?
#

For those wondering if the anime is finished: Yes, the animated production cycle for the series has concluded. The project spanned several years, beginning with the original series in 1997 and concluding with the release of AIKa ZERO in 2009.

Because the anime consists of a primary series, a prequel, a sequel, and a side story, viewers who watch the entire anime collection will get a complete experience of the animated narrative. While there are manga adaptations—such as AIKa Zero—that provide more content, the anime journey itself reaches a definitive end with the later OVA series.

If you enjoy deep-diving into the lore beyond the screen, you can buy the manga to expand your knowledge of this sunken world.

Audience and Appeal
#

Agent Aika is best suited for viewers who enjoy the “treasure hunting” trope combined with high-energy action. However, it is important to note that the series leans heavily into ecchi and fanservice. From the character designs to the specific marketing (such as special edition novel bundles), the series is designed for an older audience that appreciates adult-oriented themes alongside its sci-fi premise.

If you’re a fan of the series and want to collect some memorabilia, check out the available Agent Aika merchandise.
