Living by the sea, protecting the sea, and journeying across the sea... They're the Blue Mermaids! Because of a shift in tectonic plates around 100 years ago, Japan lost much of its area to submergence. To preserve Japan's territories, coastal cities sprung up, one after the other. Eventually, they became marine cities, and along with the expansion of sea-lanes to connect them, the need arose for a sizable staff to protect the seas. At the same time, maritime jobs were becoming more popular among women. Hence, the Blue Mermaids, tasked with keeping the seas safe, had become every female student's dream job. This is when childhood friends Akeno Misaki and Moeka China enroll in a marine high school in Yokosuka, along with other girls who share their goal of becoming a Blue Mermaid. (Source: Aniplex USA)

Saki Miyanaga is a high school freshman who doesn't like mahjong. Ever since she was a child, she would lose her New Year's gift money during her family mahjong game. If she won, her parents would be upset, and if she lost, well, she lost. As a result, she's learned to play in such a way that her score differential always remains ±0: not good enough to win, but not bad enough to lose. When we meet her, she's being dragged to her school's mahjong club by an old friend. How will a girl who hates mahjong, yet has become adept at the game as a result of her upbringing, survive in this environment? (Sources: ANN and AniDB)

With the seas under constant threat from the hostile "Abyssal Fleet," a specialized naval base is established to counter them. Rather than standard naval weaponry, however, the base is armed with "Kanmusu"—girls who harbor the spirits of Japanese warships—possessing the ability to don weaponized gear that allows them to harness the powerful souls within themselves. Fubuki, a young Destroyer-type Kanmusu, joins the base as a new recruit; unfortunately for her, despite her inexperience and timid nature, she is assigned to the famous Third Torpedo Squadron and quickly thrust into the heat of battle. When she is rescued from near annihilation, the rookie warship resolves to become as strong as the one who saved her. [Written by MAL Rewrite]

Strike Witches is set in an alternate version of 1944, where the events of World War II are very different than what we know to be true. Alien invaders known as the Neuroi came to Earth in 1939. This is not the first appearance of the Neuroi as they have appeared at seemingly random intervals throughout human history. While the Neuroi primarily attack humanity using aircrafts, their mothership is able to produce a deadly miasma, a chemical that is fatally poisonous to humans, forcing the populations of affected areas to flee their homes. The Neuroi then use the poisoned areas to plunder Earth's natural resources to use against humanity. Luckily the miasma cannot spread across water, making the ocean humanity's main line of defense against the Neuroi. With normal humans unable to fight in the miasma, witches have become the forefront of military defense against the Neuroi. Each witch is able to deploy a defensive field around themselves that not only blocks the miasma but protects them from physical attacks as well. Utilizing leg mounted machines called Striker Units to fly into combat, the witches use their magical abilities to wield devastating weapons too large and ungainly for a normal person. The series follows the battles fought by the 501st Joint Fighter Wing, who battle on the front lines to defend the British Isles from the Neuroi. Will humanity be able to take back Earth and bring peace to their home? Find out in Strike Witches!
