Does 'I Cast Fist (Celestial Grimoire - DxD)' Follow Canon Or Diverge Early?

The uniqueness of 'I Cast Fist (Celestial Grimoire - DxD)' lies in its bold fusion of the 'Celestial Grimoire' system with the high-energy world of 'High School DxD'. Most fanfics either stick to canon powers or borrow from mainstream crossover universes, but this one introduces an entirely new magic framework that operates on conceptual levels. The protagonist doesn't just punch harder or fly faster—their abilities rewrite the rules of engagement entirely. Imagine facing a devil who can suddenly manipulate 'the concept of distance' to make your attacks never reach, or an angel who enforces 'the law of silence' to disable all sound-based magic. The story thrives on these unpredictable power interactions while respecting DxD's power hierarchy, making every battle a chess match rather than a slugfest.

In 'I Cast Fist (Celestial Grimoire - DxD)', the MC throws down with a rogue exorcist first—some hotshot who thought he could bully weaklings. This guy’s got holy energy blades and arrogance to spare, but our protagonist shatters both with bare fists. The fight’s brutal; no fancy magic, just raw power meeting holy tech. The exorcist’s armor cracks under punches that feel like meteors, and his smug grin vanishes when he realizes he’s outclassed by someone who fights like a raging storm. It sets the tone for the whole story: no frills, just overwhelming force against anyone dumb enough to pick a fight.

The protagonist in 'I Cast Fist (Celestial Grimoire - DxD)' evolves from a scrappy underdog to a force of nature. Early on, he’s just a guy with enhanced martial arts skills, but the Celestial Grimoire changes everything. His power isn’t linear—it’s exponential. By mid-story, he’s trading blows with mid-tier devils and angels, his fists carving craters into battlefields. What’s wild is how his abilities synergize. The Grimoire grants him magic resistance, letting him bulldoze through spells that would vaporize others. His signature move? Channeling raw cosmic energy into his strikes, turning punches into localized apocalypses. Late-game, he’s borderline invincible, shrugging off dimensional attacks and rewriting reality with his knuckles. The scaling feels earned, not cheap.

while it's primarily an action-packed crossover, there's definitely romance sprinkled throughout. The protagonist's interactions with certain characters from the 'High School DxD' universe carry that classic will-they-won't-they tension. Rias Gremory's usual charm gets interesting counterplay from the OC's grimoire powers, creating some hilarious yet sweet moments. What stands out is how the romance doesn't overpower the plot—it feels organic, like when combat partners gradually develop deeper bonds during life-or-death situations. The fic handles attraction through subtle gestures rather than grand confessions: shared glances after battles, playful teasing about each other's fighting styles, and those quiet moments when they patch each other up. If you enjoy action with a side of slow-burn relationship development, this delivers.

The blend of comedy and action in 'I Cast Fist (Celestial Grimoire - DxD)' is pure genius. The protagonist's ridiculous ability to solve problems by literally punching them creates hilarious scenarios—imagine someone defeating a demon lord with a well-placed jab to the nose. The action sequences are over-the-top, with flashy martial arts moves colliding with supernatural powers, but the comedy comes from how absurdly straightforward the MC's approach is. He doesn't need elaborate spells; his fists *are* the solution. The contrast between the serious, high-stakes world of 'DxD' and this guy's unshakable belief in brute force makes every fight both thrilling and laugh-out-loud funny. The supporting characters' reactions sell it—angelic beings facepalming at his methods, devils bewildered by his lack of finesse. It's a perfect mix of hype and humor.

Honestly, when I want something that tracks the anime beat-for-beat, I look for the label 'retelling' or 'canon-compliant' and check the author's notes right away. Those little notes usually tell you whether the writer intends to reproduce events exactly as in 'Highschool DxD' or just use the setting and characters as a springboard. I tend to avoid fics that drop OCs into the main plot early on — faithful retellings usually keep the original cast and only expand internal thoughts, fight descriptions, or background moments. A practical checklist I use: (1) read the first couple of chapters and compare timestamps/events to the anime episodes; (2) scan tags for words like 'canon', 'retelling', 'anime-accurate', or 'episode-by-episode'; (3) look at comments/reviews — readers often call out divergences immediately. Also, platform matters: Archive of Our Own and FanFiction.net both host many 'faithful' retellings, but AO3's tagging system makes it easier to find works explicitly marked as 'canon-compliant'. If you want something that adds flavor without rewriting the story, search for fics described as 'expanded canon' or 'internal monologue retelling' — those keep plot points identical but deepen character reactions and fight descriptions. Personally, I enjoy that blend: it feels like watching the anime with director's commentary in prose form.

I can confidently say 'DXD Scarlet Nexus in DXD' isn't part of the official canon. The original series, penned by Ichiei Ishibumi, sticks to a very specific lore and character roster, and this crossover doesn't fit into that framework. But here's the fun part—just because it's not canon doesn't mean it lacks value. Fan creations like 'Scarlet Nexus in DXD' often explore wild what-if scenarios, blending worlds in ways that official material wouldn't dare. The charm lies in seeing characters like Issei Hyoudai interact with the psychic warriors from 'Scarlet Nexus,' even if it's purely imaginative. What makes these crossovers fascinating is how they reinterpret powers. Imagine Yuito's psychokinesis clashing with Issei's Balance Breaker, or Kasane's time manipulation weaving into the DxD universe's supernatural politics. The dynamics are fresh, even if they don't align with canon events. For fans hungry for more content, these stories are a playground. They might not advance the official plot, but they offer creative twists that keep communities buzzing. The key is to enjoy them as standalone adventures rather than extensions of the original narrative.

I've spent way too much time dissecting crossovers like '[HP X DXD] Master of a Universe,' and whether it sticks to canon really depends on what you mean by 'follow.' The fic doesn’t just regurgitate events from 'Harry Potter' or 'High School DxD'—it bends them until they scream. The protagonist (usually a ridiculously overpowered Harry) doesn’t just stumble into the DxD world; he bulldozes through it, rewriting rules as he goes. Canon characters like Rias or Issei still show up, but their arcs get hijacked by Harry’s presence. Imagine Rias’ peerage suddenly having to deal with a wizard who treats Sacred Gears like party tricks—it’s entertaining, but it’s not the DxD you remember. The author plays fast and loose with power systems too. Magic from HP gets mashed up with DxD’s devil contracts, and the result is chaos. Harry might use a Patronus to scare off a stray devil one chapter, then invent a new spell to counter a Longinus the next. It’s fun, but if you’re a stickler for lore consistency, this’ll give you whiplash. The fic cherry-picks canon moments (like the Rating Game tournaments) but often flips outcomes because Harry’s involvement changes everything. Even the timeline gets shaky; sometimes it feels like the DxD events are happening years earlier or later than they should. That said, the deviations are the whole point—it’s a power fantasy where canon exists to be upended. Where the fic surprisingly holds the line is with character personalities. Rias is still cunning, Issei’s still a lovable pervert, and Dumbledore’s still manipulative (though Harry might call him out on it faster). The dialogue nails their voices, even when the plot goes off the rails. But let’s be real: nobody reads this for accuracy. They read it to see Harry break the DxD universe over his knee—and on that front, it delivers.

Being a die-hard fan of 'High School DxD', I dove deep into 'DxD My Journey' to see how it stacks up. The story definitely takes creative liberties—it carves its own path rather than rigidly following the anime's timeline. Key events like the Rating Games and Rias’s arranged marriage appear, but they’re reshuffled or reimagined. Issei’s power progression feels more personal here, with slower, emotional beats the anime glossed over. The biggest twist? New characters weave into the lore, like a rogue exorcist who challenges Issei’s ideals. The core themes—friendship, ambition, and demon politics—remain intact, but the journey feels fresher, like a parallel universe where choices diverge. Fans of the anime’s fast-paced battles might miss the adrenaline, but this version digs deeper into character flaws and growth. Sacred Gears evolve differently, and even minor factions like the Fallen Angels get expanded roles. It’s not a carbon copy—it’s a love letter with its own rhythm.

Honestly, when I dive into Wattpad and hunt for 'Re:Zero' stories, I find a chaotic but lovable buffet — some dishes try to recreate the original recipe and others throw in pineapple and call it a remix. A lot of fan authors on Wattpad either pick a canon moment and retell it with their own spin or build alternate universes where Subaru’s choices, powers, or relationships are radically different. You’ll see canon-friendly retellings that follow the light novels or the anime beats pretty closely, but even those often compress scenes, change pacing, or amplify romantic angles to satisfy readers who want more emotional beats. Then there are the wildly divergent ones: genderbent Subarus, high-school AUs, crossover fics with other franchises, or stories where Subaru never gets Return by Death. Tags like 'canon-compliant', 'AU', 'fix-it', or 'crossover' are your friends — read the author’s notes and early chapters to judge fidelity. If I want something as close to the original world as possible, I check whether the writer references specific volumes or chapters and how they handle lore. But honestly, part of the charm is stumbling on a take that reimagines a scene I love; it’s just good to go in with expectations so you don’t get disappointed.
