Natsuki Subaru, an ordinary high school student, is on his way home from the convenience store when he finds himself transported to another world. As he's lost and confused in a new world where he doesn't even know left from right, the only person to reach out to him was a beautiful girl with silver hair. Determined to repay her somehow for saving him from his own despair, Subaru agrees to help the girl find something she's looking for.
The players of a virtual reality MMORPG, Sword Art Online, are trapped and fighting for their very lives. After it is announced that the only way to leave the game is by beating it, Kirito—a very powerful swordsman—and his friends take on a quest to free all the minds trapped in Aincrad.
Kanie Seiya, a smart and extremely narcissistic high school student, believes that the beautiful but reserved Sento Isuzu has invited him on a date at an amusement park called Amagi Brilliant Park. Much to his chagrin, not only is the location a run-down facility, the supposed date is merely a recruitment tour where Sento and Princess Latifa Fleuranza, the owner of the theme park, ask him to become the park's new manager. Their cause for desperation? As stipulated in a land-use contract, Amagi has less than three months to meet a quota of 500,000 guests, or the park will be closed for good and the land redeveloped by a greedy real-estate company. Seiya is won over by the revelation that Amagi is no ordinary amusement park; many of its employees are Maple Landers—mysterious magical beings who live in the human world and are nourished by the energy created by people having fun. Entrusted with the hopes and dreams of this far-off enchanted land, Seiya must now use his many skills to bring Amagi back on its feet, or watch it crumble before his eyes. [Written by MAL Rewrite]

The setting is a parallel world to Fate/stay night where the Greater Grail mysteriously disappeared from Fuyuki after the Third Holy Grail War. After many years of silence, around the same time as the Fifth Holy Grail War would have happened, the Yggdmillennia, a family of magi, openly declares their secession from the Mage's Association, and that they are in possession of the Grail. The Association dispatches fifty magi to retrieve it, and all but one are instantly slaughtered by a mysterious Servant. The one remaining manages to activate the reserve system of the Greater Grail, allowing for the summoning of fourteen Servants in total. In the city of Trifas, two factions will fight for the control of the sacred relic, each of them possessing their own team of seven Servants: the Black Faction whose members are part of Yggdmillennia, protecting the Grail, and the Red Faction whose members were sent by the Mage's Association, trying to take the Grail back. For an event of this scale, the Grail itself summons its own Servant, the holy Ruler, to oversee the conflict. This marks the start of the Great Holy Grail War.
