With a boisterous merman as his new roommate, Tatsumi's normal life won't be returning anytime soon, not to mention Wakasa's aquatic friends—Takasu, Mikuni, and Maki—often show up uninvited, making them all quite a handful for the high school student.

From the depth of the seas rises an evil monster, bent on taking over the human world: Ika Musume. She's ruthless. She's menacing. She's... an adorably non-threatening little girl who makes an awesome squid-ink spaghetti?
Ika Musume has come out of her home in the ocean on a quest to punish humanity for polluting her waters. With squid tentacles for hair and some pretty useful ink-spitting skills, Ika Musume is sure she'll have no trouble invading Earth. What she didn't account for were the Aizawa sisters, rough and tumble Eiko and deceptively mellow Chizuru, who immediately bully her into working as a waitress in their seafood restaurant by the shore.
Ika Musume decides to take this chance to learn more about the human world, having silly adventures, meeting lots of strange characters, and never once letting world domination out of her sights.

Many years ago, after the end of a bloody world war, mankind took shelter in six city-states that were peaceful and perfect... at least on the surface. However, Shion—an elite resident of the city-state No. 6—gained a new perspective on the world he lives in, thanks to a chance encounter with a mysterious boy, Nezumi. Nezumi turned out to be just one of many who lived in the desolate wasteland beyond the walls of the supposed utopia. But despite knowing that the other boy was a fugitive, Shion decided to take him in for the night and protect him, which resulted in drastic consequences: because of his actions, Shion and his mother lost their status as elites and were relocated elsewhere, and the darker side of the city began to make itself known.
Now, a long time after their life-altering first meeting, Shion and Nezumi are finally brought together once again—the former elite and the boy on the run are about to embark on an adventure that will, in time, reveal the shattering secrets of No. 6.

*The Second OVA of Kono Dan series.
They say look before you leap and make sure you can swim before you go in the deep water, but when a picture of his late grandfather falls into the ocean, Shima jumps in after it without thinking. Nearly drowning as a result, he is instead saved by a very perfect stranger... one whose strangeness extends to only being human from the waist up!
For Shima, who's always felt like a fish out of water himself, it's more than just a revelation, and the young man and merman quickly begin to bond in ways neither anticipated. And yet, it's going to be far from easy sailing. After all, Shima and Isaki aren't just from opposite sides of the tracks, they're from entirely divergent species, and swimming in separate gene pools may make maintaining a long term relationship a whole different kettle of fish!
