The Holy Grail War is a battle between seven magicians who each summon a mythical hero to fight for their cause. Shirou, a twice orphaned high school boy, had so little magical talent that his foster father did not bother teaching him about the war and its meaning. Thanks to that lack of foresight, Shirou finds himself in a bit of a pinch when he accidentally summons a hero of the strongest class, and is sucked into the fray. The Grail grants the winner any wish they have. But driven by an unyielding sense of justice and self-sacrifice, for what will Shirou fight?
It is said that humans fear what is different, and that such fears drive much of human behavior. Naoto and Nayao learned the brutal truth of this statement when they see the looks on their parents’ faces, the day they were sent to an isolated laboratory to live out their youth. Their crime? Possessing inherent psychic abilities. Yet now, the brothers have escaped and are at last free to experience the world, but they soon discover that their prison was also their protection from the outside world. The question is, are their powers more dangerous to themselves, or those around them?
On the eve of nobleman Oz Bezarius's fifteenth birthday, he and his loved ones gather to celebrate in a coming-of-age ceremony. But after Oz steps under a long-stopped clock and the hands finally move once more - thus fulfilling a mysterious prophecy - he is violently thrown into the legendary prison known as the Abyss by three cloaked intruders. Existing in another dimension, the Abyss is home to lifeforms born within its walls known as Chains; these beings can only live in the real world if they make contracts with humans, binding their power to the person's body. However, there's a catch - in time, the human will be overcome by the Chain's power and then thrown into the deepest level of the Abyss. When Oz wakes up in the Abyss he is quickly attacked by hungry Chains, only to be saved by one named Alice - a Chain who appeared just before he was thrown into the prison. Together, the two make a contract and return to the real world, where they are enlisted into the Pandora organization - a group researching both the Abyss and the trio that threw Oz into it. Along with members of Pandora, the duo searches to find Alice's lost memory fragments that are scattered throughout the world, to discover the secrets of the Abyss, and to determine if there's a way their contract can be broken without killing either Oz or Alice.
PH and F/SN definitely top some of the more similar anime I've seen in a long time. Usually I have trouble thinking of recommendations, but not for thse two. For one, they both involve a male protagonist who... is "coming of age" and through a series of events, ends up having a very strong female lead protecting them. And what I like best is that, they clearly establish that Saber/Alice both dominant the world they're in (and they don't just fall over when their opponents come at them). They focus more on Oz than Shirou (I think) in terms of character development but they both pretty much grow on you.
In terms of plot though, they both involve some sort of "save the world" theme, although I think PH is more about revealing the past while F/SN is more about saving the future. PH definitely has a stronger mystery feel and (despite the poor animation) the ending isn't the most conclusive. On the other hand F/SN is based off a game, so it definitely has a conclusion and romance to boot!
