Seaside Cafe is hardly what comes to mind when one thinks of a maid cafe. Hastily rebranded to jump in on the maid trend, Seaside Cafe carries no tea, offers very little in the way of service, and only gets customers from the local shopping district. Despite the cafe's humble offerings, this is where Hotori Arashiyama chooses to secretly work after school. Balancing high school, work, family, and a love life can be difficult, and Hotori manages to stumble through without the slightest bit of grace. With the help of her friends and family, she tries to navigate her way through the wild world of adolescence where barely anything normal occurs.

When middle school kendo champion Ayumu Tanaka begins his first year in high school, he does not take the expected route of joining the Kendo Club; he signs up for the unofficial Shogi Club instead. His sole motive is falling in love at first sight with Urushi Yaotome—the club's president and only member—and will do anything to get closer to her. However, Ayumu decides not to confess to Urushi until he can beat her in a match of shogi fair and square. Naturally, this self-imposed hurdle is a formidable challenge for Ayumu to overcome, as Urushi is far more experienced at the game and sees through his every strategy. Nevertheless, this does not stop him from praising her looks, her skill, or even her smile, which, coupled with Ayumu's expressionless face and direct approach, makes Urushi constantly blush beet red. Learning more about shogi and the charming player sitting across from him, Ayumu inches toward making his confession with each exciting round they play together—even if it is one pawn at a time!

Long before the era of prehistoric man, an advanced alien species inhabited Earth. Negligent of the power they held, these beings ultimately caused their own demise. However, the aliens left behind a warning to future civilizations on indestructible tablets: to destroy any remains of the ruinous technology created by their kind. In modern times, the ARCAM Corporation and their paramilitary unit—the Spriggans—seek to seal the relics away and prevent renegade actors from exploiting their powers. Following ARCAM's recent discovery in the Ararat Mountains of what is believed to be the mythic Noah's Ark, Spriggan Yuu Ominae has been dispatched to investigate. However, the site is ambushed by the US Machine Corps—a radical faction of the Department of Defense led by Colonel MacDougall. On the Pentagon's orders, MacDougall seeks to secure ARCAM's lead scientist and seize the artifact. Teamed up with fellow Spriggan Jean Jacquemondo, Yuu must stop MacDougall and the Machine Corps' elite soldiers from advancing on the Ark before it is too late.

In the Victorian era, the British Empire is bustling with the energy of the steam-powered industrial revolution. Following in the footsteps of his famous family of inventors, James Ray Steam enjoys his youth in Manchester helping at local factories and stealing components for his own creations. One day, he receives a package containing a strange ball with an attached valve from his grandfather, who has been working in the United States alongside Ray's father. However, it is not long before people from the O'Hara Foundation storm into his house demanding he hand it over. Confused and afraid, Ray attempts to flee to the home of his grandfather's colleague, Robert Stephenson, with pursuers hot on his trail. While Ray seeks to piece together the secret of the ball and discover the power it contains, it seems practically everyone in the British Empire is ready to seize it from him.
