Fanfic / Fate/stay night: The Dragon of the Seventh Heaven

Go To

Fate/stay night: The Dragon of the Seventh Heaven is an Alternate Universe Crossover between the Fate/stay night and High School D×D written by Starlight's Poet.

Issei Hyoudou was always normal. And a pervert. The odds of him ever finding a girl were slim. So when Yuuma Amano approached him, there were no words that could describe the happy feeling in his heart.

And then she attempted to kill him, revealing her true nature.


At that moment, however, Issei's desperate pleas for someone to save him woke something inside of him. A secret that he was not aware of. Something that a certain vampiric troll is watching with great enthusiasm.

As for Raynare...the last thing she could have expected was to find Tamamo-no-Mae before her, proclaiming Issei Hyoudou her husband and ready to kill her.

This story contains examples of the following Tropes:

  • Accidental Marriage: What Issei's summoning of Tamamo essentially counts as. Not that Issei is complaining.
  • Action Girlfriend: Or Action wife as Tamamo would claim. As a Servant, regardless of class, she would easily be regarded as being very powerful in the DxD universe. However, thanks to the Heaven's Feel, she's been revived in her complete state.
  • Adaptational Badass: Tamamo, if you can believe it. All variants of Tamamo-no-Mae are fragments of the actual character, known as the Tamamo Nine, and each wants to become the true Tamamo-no-Mae. Thanks to Issei reviving Tamamo-no-Mae via Heaven's Feel, the Tamamo Nine have been gathered, thus unlike in Fate/EXTRA, she's at full power constantly. Meaning she can trounce virtually almost anyone easily, except perhaps barring the likes of Great Red or Trihexa.

  • Adaptational Early Appearance: Lint Sellzan. She first appeared in Volume 22 in the main series. Here, she's with the Stray Exorcists tasked with stealing Asia's Sacred Gear and kill Issei.
  • Adapted Out: The Riser Arc is not going to be featured in the story, or at the very least is going to be postponed, as the Arc following the Holy Maiden storyline focuses on the ramifications of Issei reviving one of the most prominent figures in Shinto myth.
  • Admiring the Abomination: Nothing could possibly play this trope straighter than Issei finding Fou, AKA Primate Murder adorable.
  • Ambiguous Situation: In Chapter 7, shortly after Issei informs Tamamo that Asia is dying, Tamamo has a conversation with the Nine. Near the end of the conversation, the Tamamo in charge orders her Shark, Cat and Tamamo-vitch selves to go help the others restrain her. It's unknown who she is referring to, but given that Tamamo is technically a Beast, it's possible she has her other seven aspects working to keep the Beast variant under check.
  • Ascended Extra:
    • Issei's classmate Aika Kiryu ends up getting dragged into his adventures and learning about the supernatural.
    • Lint Sellzan also somewhat applies. She was introduced fairly late into the story, near the end in fact, but here she has a more prominent role as one of the Stray Exorcists asked to kill Issei. She later accepts Rias' offer to become a member of Peerage, taking Issei's place as her Pawn.
  • Back from the Dead: If you're familiar with the magical lore of Type Moon, then you'll remember that Heaven's Feel is the power to revive a deceased soul with negative consequence. In an AN , the reason why Issei has Heaven's Feel is because of the events of Fate/Grand Order have weakened the boundaries between universes, with the Nasuverse's influence leaking into DxDs. Additionally, because he summons Heroic Spirits, the individuals in question are revived at full power, rather than being limited to a specific skillset that their Servant body forces on them.
    • Tamamo is the first Heroic Spirit summoned, due to Issei thinking about his ideal girlfriend and wishing someone would save him before he's killed by Raynare.
    • Issei himself undergoes this when he's shot and killed by Freed. The Heaven's Feel constructs a new body after his old one died. Hilariously, he was Naked on Revival.
    • Jeanne d'Arc follows Tamamo when Issei Rage Against the Heavens before he breaks down and tearfully begs Him to save Asia as she is about to die after the botched attempt from having her Sacred Gear removed.
    • According to Word of God, the next Heroic Spirits to be revived are Musashi, who will act as Issei's teacher, and Frankenstein's Monster, who's role has yet to be revealed.
  • Badass Normal: What the author claims Issei will be. Starlight's Poet, the author, promised that he wouldn't remain weak and the constant Distressed Dude while being coddled. Makes sense, as compared to everyone else, who is a supernatural being, Issei is still a normal human who does not have a Sacred Gear in this story. Word of God even states that his teacher will be Musashi, who is stated to be summoned next after the next arc is complete.
  • Beware the Nice Ones: Tamamo may be all smiles, but she is the Avatar of Amaterasu-no-Mikoto for a reason. Rias and Sona and co. learned that the hard way. And Issei fears what may happen if he ever tries to mention having a harem before her, fully aware that she does not like the idea of sharing.
  • Berserk Button: For the author. People constantly sending him suggestions on what Heroic Spirits he should summon is enough to tick him off.
  • Brought Down to Normal: By ripping off Raynare's wings - the symbol of her power - Tamamo effectively rendered her to the level of the average human being. It's also played as being a Fate Worse than Death, as Raynare has admitted she hates humans and is now on the same level as they are.
  • Came Back Strong: What Issei's Heaven's Feel does for Heroic Spirits. Rather than being summoned as Servants, and therefore with their powers limited to a specific load out, they're summoned at their peek when they were alive and have all powers accessible.
  • Dramatic Irony: No one, not even Tamamo herself, except for Zelretch is aware yet that Tamamo is from another universe.
  • Eldritch Abomination: Fou. There's a reason it's called Primate Murder.
  • Fate Worse than Death: What Tamamo believes to be Raynare's fate after defeating her. With her wings ripped from her back, she has virtually been stripped of all of her power as a Fallen Angel, and is now reduced to a human - the same beings she detested so much.
  • Fish out of Temporal Water: Since there is no Holy Grail to provide her with information, Tamamo doesn't know anything about the modern world and needs Issei or others to explain things to her like schools. Much to the Devils' surprise, she doesn't even know about modern magical terms like Sacred Gears, of the three-way war between Angels, Fallen Angels, and Devils, or of the current state of the Youkai, but this is understandable because Tamamo is from the Nasuverse where these terms and events do not exist.
  • Freak Out: The Devils and Tamamo of all people have one when they see Fou, one of the Beasts of Gaia and the infamous Primate Murder on Issei's shoulder.
  • God in Human Form: Tamamo-no-Mae. She is the avatar of the Japanese goddess of the sun.
  • How Do I Shot Web?: Issei has no idea how to activate Heaven's Feel at will.
  • Identity Impersonator: Issei introduces Tamamo to his parents as Yuma Amano, aka Raynare's human alias.
  • Info Dump: Zelretch explains the Heaven's Feel to Issei and its applications, though most of it goes over his head.
  • In Spite of a Nail: Despite many factors being present, such as Issei possessing Heaven's Feel, which can revive anyone without consequence, Asia still dies and is Reincarnated by Rias. At that point in time, Issei still doesn't fully understand how to use the Heaven's Feel, or that it has rules in place for it to be used.
  • Killed Off for Real: Freed, courtesy of Issei chopping off his head.
  • Late-Arrival Spoiler: Anyone who hasn't reached the end of the first act of Fate/Grand Order will be shocked to learn that the tiny white fluffy ball of cuteness that is Fou is, in actuality, one of the Beasts of Gaia.
  • Mind Hive: Since Tamamo was revived in full, rather than in the body of a Servant, the Tamamo Nine are all sharing the same body, with the Caster Servant aspect being the dominant persona in control. That said, Tamamo-vitch implies that any of the Nine can take the driver seat.
  • Mistaken for Cheating: When Issei ends up summoning Jeanne d'Arc, Tamamo angrily thinks he's cheating on her. Jeanne puts a stop to it by clarifying she is not interested in Issei and came to help.
  • Mistaken for Gay: Jealous of Issei's relationship with Tamamo, Matsuda and Motohama start spreading rumors that he is gay when they see him hanging out with Kiba.
  • Mistaken Identity: Several of the supernatural factions think that Tamamo is the DxD verse's own Tamamo. Some don't believe it, however, citing the Killing Stone, DxD Tamamo's resting place, as being still intact.
  • Mythology Gag:
    • When Issei gives Tamamo a tour of his school, Tamamo says the school environment seems vaguely familiar somehow, a reference to Fate/EXTRA.
    • Zelretch, when explaining things to Issei in their meeting, mentions an event in one of his dimension's parallel worlds that resulted in human history being incinerated and a cataclysmic event, referring to the events of Fate/Grand Order.
  • Nosebleed: Issei tends to get these when Tamamo's seductive antics push him too far. They even knock him out, much to his frustration.
  • Not-So-Imaginary Friend: Fou starts appearing in Issei's dreams, which he thinks is strange but doesn't think much off. Imagine his surprise when he appears in real life and the others can see him.
  • Off with His Head!: How Freed goes out. Issei chops off his arm to prevent him from fighting back, and then proceeds to lop off his head. Toyohisa would be impressed!
  • Oh, Crap!: Several.
    • In Chapter 1, when Raynare's attempt to kill Issei fails thanks to him inadvertently summoning Tamamo-no-Mae. And Raynare promptly receives this beautiful gem:
      Tamamo: Prepare to die, bitch.
    • Another one happens in Chapter 2, when the Devils of Kuoh confront Issei and Tamamo, with the latter becoming furious that the Devils had the audacity to claim a part of Japan as their own. The Devils realize they have pissed off a being who could easily kill them all.
  • Powerful and Helpless: Tamamo realizes she never learned any healing spells, so for all her godly power, she can't do anything to stop Asia from dying, forcing Asia to be reincarnated as a Devil. Issei possesses Heaven's Feel, but since he is still figuring out its kinks, has no idea how to use it to heal Asia. Issei ends up summoning Jeanne d'Arc, who doesn't have any healing powers either, but she convinces Asia to let Rias Gremory reincarnate her as a Devil.
  • Rage Against the Heavens: Issei angrily rants against God for the fact that Asia is dying, plus everything Asia suffered in her life. Fortunately, this activates Heaven's Feel and summons Jeanne d'Arc. While Jeanne lacks the ability to heal her, she manages to soothe her and convince her that being reincarnated as a Devil, which Asia had been reluctant to do, will not be a betrayal of God.
  • Royal "We": Invoked by Tamamo, when all members of the Tamamo Nine agree on something. Usually doubles as an Oh, Crap! moment, because when you hear Tamamo talking like that, you know you are screwed.
  • RPG-Mechanics Verse: Sort of. The story's setting isn't remotely like that of a Video Game, but the Heaven's Feel seems to work like this.
    {{Error. Connection lost.}}
    {{Attempting reconnection...}}
    {{Error! Reconnection impossible. Cause: Severe Brain Injury.}}
    {{Odds of survival: zero.}}
    {{Opening Circuit Pathways...}}
    {{Circuit Connection Established.}
    {{Beginning Reconstruction.}}
  • Shout-Out: Issei dreams of being in what can only be described as a Station of Awakening knock-off, complete with a stained glass mural for a floor and a door of heavy significance.
  • Spared by the Adaptation: In a sense. Tamamo is summoned in time to stop Raynare from killing Issei. This means Rias doesn't have to revive him as a Devil and he remains a human. Raynare and the other Fallen also count, though Tamamo inflicted a Fate Worse than Death on Raynare by ripping out her wings and reducing her to a feeble state.
  • Speaks Fluent Animal: Tamamo can understand what Fou says, while Issei can't.
  • Superpower Lottery: Issei has Heaven's Feel. I repeat. Issei. Has. Heaven's Feel.
  • The Great Political Mess Up: Tamamo clearly is not happy with the fact that Devils have established themselves in Japan. In fact, when she first hears of it, she goes ballistic.
  • Zettai Ryouiki: A few female students have this, such as Aika. Special mentions go to Tamamo, however, who has Grade B.
