FateBlack Reflection

Fate/Black Reflection is a Crossover Fanfic between Fate/stay night and Bleach by Nameless Flame Wielder, in which Kurosaki Ichigo is forced to participate in the 5th Heaven's Feel Grail War when he is attacked by Lancer and inadvertently summons a Servant of his own.

The story begins simply enough: Ichigo and his friends are called in to investigate a series of deaths and disappearances in a nearby town, which Soul Society believes to be connected to the events that occurred ten years ago in the same city.

The story appears to be a combination of the Fate and Unlimited Blade Works Routes, with Bleach thrown into the mix. Although the author has mentioned that pieces from the HF route will be incorporated as well. Possibly one of the best aspects of this story is the writing, Nameless has a solid grasp on the characters of both universes, and it shows.

Tropes used in Fate/Black Reflection include:

 * Adaptational Badass:  have individually been developing spiritual powers.
 * Also Tatsuki, who before the story's start, was Yoruichi's apprentice and could focus her spirit energy into her punches and kicks.
 * Big Bad Ensemble: Kirei & Gilgamesh, versus Caster, versus Zouken.
 * Big Damn Heroes: Quite a few instances.
 * The most spectacular of which is
 * Blood Knight: Both Lancer and Ichigo show their Blood Knight tendencies during their Intense rematch.
 * Rider is also this, albeit to a lesser extent.
 * Conflict Ball: Somewhat; see below.
 * Crowning Moment of Awesome: Ichigo. Versus. Saber. What more is there to say?
 * Crowning Moment of Heartwarming: Ichigo's response to Rider's identity. Jerk with a Heart of Gold indeed.
 * Also worth mentioning is Rider's reaction to this moment.
 * Didn't See That Coming: When Lancer and Bazett have their reunion they manage to keep Kirei from understanding what they are talking about by simply speaking in Gaelic, a language Kotomine doesn't know. He's actually impressed that they managed to outwit him so simply.
 * Five-Man Band:
 * The Hero: Ichigo
 * Deuteragonist: Rider
 * The Lancer: Rukia & Tatsuki
 * The Smart Guy: Uryu
 * The Big Guy: Chad
 * The Chick: Orihime
 * Sixth Ranger:
 * Honor Before Reason: Rider observes that Ichigo has a case of this and is worried it will get him in serious trouble, especially considering he's fighting in the grail war.
 * Poor Communication Kills: The two major groups of good guys are trying to kill each other, mostly because they don't seem to know squat about the right way to find out who is a potential ally and who isn't - Ichigo and his True Companions are acting all mysterious and interrogative, with ominous questions being thrown out ("Why do you want the Grail?") Shirou and his ally's aren't much better, since their first response to this is to attack the people who haven't done anything yet. It gets especially bad when Saber  and Ichigo gets pissed off in response.
 * As Chapter 22 shows, the Fuyuki group are worse at it - while they've no reason to trust the ominous people, their first response appears to be "attack first, ash questions later". Especially Archer.
 * Ship Tease: There are a few... suggestive elements regarding Ichigo and Rider's partnership. Not least of all Rider . But it's still too early to tell.
 * Also too early to say for sure but there is a bit between Chad and Ayako as well.
 * And Rider keeps flirting with Tatsuki.
 * Spared by the Adaptation: Bazett manages to survive due to a timely find and heal courtesy of Orihime.
 * Super-Powered Evil Side: Thanks to Caster's experiments on the Hollows,
 * Unskilled but Strong: A majority of Soul Reapers tend to fight using the power of their zanpakutos and their kidou spells rather than their actual weapon technique. Ichigo notices this compared to Lancer, a servant of the spear, who is both strong AND skilled, with unmatched speed and accuracy with the weapon. Not that he's complaining.
 * White and White Morality: Ichigo's group vs. Shirou is made of this, along with Poor Communication Kills - they're definitely all good guys with noble intentions, but because they're being either over-cautious or reckless, they've so far only succeeded in making enemies of each other.
 * Blue and Orange Morality: Ichigo's group vs. All the other magi and all the Heroic Spirits. Soul reapers are trying to achieve balance of souls between the worlds and keep casualties to a minimum. The other participants in the Holy Grail War, excluding Shirou, are here to get the Grail by whatever means and keep anyone from finding out. Their morals aren't just different, they're incompatible.
