Stratos 4

Tokyo has been sunk into the ocean, along with most of the world, during a large-scale land subsidence! Aika Sumeragi is a salvager who works for a small company run by a father and daughter tandem. Alas, the company isn't exactly successful, and money is needed desperately. Thus, Aika accepts the very dangerous job of acquiring an artifact called Lagu for a hefty sum. The boss's daughter Aida Rion joins Aika on this particular mission, and the two set off.

Renton Thurston is a 14-year-old boy who lived with his mechanic grandfather in a backwater town. Every day he dreamed of being with the mercenary "Light Finding Operation (LFO)" aircraft pilot group "Gekkostate" and riding "Trapar" particle waves-- a sport called "Riffing"-- with their charismatic leader Holland, especially when faced with his father's acclaimed past or his grandfather's desire to protect him. When a young girl named Eureka riding the original LFO, the "Nirvash typeZERO", asks his grandfather for a tune-up, she inadvertently brings the attention of the military to the garage; as a result, the garage is destroyed and Renton is forced to deliver a new type of interface-- the "Amita Drive"-- to the Nirvash. After a heated fight in which the Nirvash destroys the military LFOs by unleashing an immense amount of power, Renton is invited into Gekkostate. However, he quickly realizes that behind the facade of a traveling group of mercenaries is a very bitter reality.

When Keitaro was a child, he was friends with a little girl. When the girl had to move away, the two made a promise to meet each other at Tokyo University when they grew up. Years later, Keitaro has failed his entrance exam twice, and his parents refuse to support him any longer. His grandmother gives him refuge and employment as caretaker of her inn, which just happens to serve as a female dormitory. The eclectic group of tenants tease, annoy and berate him to no end. Still, Keitaro won't ever give up his promise to meet his childhood friend again, even though he can't remember her name.

The future Earth; with over 80% having been annihilated in a great war, the rest live under the dominion of a race known as The Third. These beings possess a third Space Eye on their foreheads, and watch over the Earth and it's remaining populace, granting it a limited amount of technology; those who infringe on the so-called Technos Taboo are harshly dealt with. Meanwhile, Honoka, a desert wanderer, along with her sand tank's sentient AI, Bogie, makes her living as a jack-of-all-trades, performing whatever tasks folks may require. This ranges from simple deliveries and escorts to giant insect exterminations. The only task she refuses to do is take human life. Nonetheless, her skill and grace with the katana has earned her the name "Sword Dancer". However, upon rescuing a quiet wanderer named Iks, who also holds the attention of the Third, she finds herself starting to think more deeply about her own inner thoughts and emotions.

Nichijou primarily focuses on the daily antics of a trio of childhood friends-high school girls Mio Naganohara, Yuuko Aioi and Mai Minakami-whose stories soon intertwine with the young genius Hakase Shinonome, her robot caretaker Nano, and their talking cat Sakamoto. With every passing day, the lives of these six, as well as of the many people around them, experience both the calms of normal life and the insanity of the absurd. Walking to school, being bitten by a talking crow, spending time with friends, and watching the principal suplex a deer: they are all in a day's work in the extraordinary everyday lives of those in Nichijou.

The reformed marionettes Tiger, Luchs, and Panther are sent to stay with Otaru to learn more about being human. A new mysterious marionette named Marine also appears.
