Is O Story Considered Canon In The Anime Universe?

OADs are such a fascinating gray area in anime! From my experience, whether they're canon depends entirely on the series. Take 'Attack on Titan'—their OADs like 'No Regrets' delve into Levi's backstory and are absolutely considered canon since they adapt spin-off manga written by the original creator. But then you have shows like 'Ouran High School Host Club' where the OADs are just fun bonus episodes with zero plot relevance. What really interests me is how studios use OADs differently. Some, like 'Fate/stay night: Unlimited Blade Works', use them to adapt vital material that couldn't fit in the TV run. Others treat them as pure fanservice—'Food Wars!' has OADs that are basically cooking tutorials with characters. I always check if the original manga author was involved in the OAD script; that's usually the best indicator of canonicity.

The whole 'are OAVs canon?' debate is such a rabbit hole! From what I've seen, it totally depends on the series. Take 'Fullmetal Alchemist'—some of those early OAVs felt like fun side stories, but then 'Brotherhood' later made certain events from them relevant. Meanwhile, the 'Attack on Titan' OAVs dug deeper into Levi's backstory, and since Isayama was involved, they absolutely feel like part of the main timeline. But then you get stuff like the 'Death Note' bonus episodes, which are clearly just playful what-ifs. Studios rarely clarify canon status upfront, so I usually judge by how much the original creator participated. If the OAV ties directly into character development or fills plot gaps without contradicting the source, I treat it as semi-canon until proven otherwise. That 'Durarara!!' OAV about Izaya's younger sister? Chef's kiss for adding layers to his messed-up psyche.

The ONA format is such a wildcard in anime! Some studios use it to drop bonus content that doesn't impact the main storyline, like those hilarious beach episodes in 'My Hero Academia' that got released as ONAs. But then you have cases like 'Attack on Titan: Lost Girls' which absolutely fleshes out crucial character backstories. I binge-watched 'BEASTARS' Season 2's ONA episodes last weekend, and they actually bridged some manga gaps the TV version skipped. What fascinates me is how streaming platforms are changing the game - Netflix's 'Devilman Crybaby' was technically an ONA that became the definitive adaptation. My rule of thumb? Check if the original creator was involved. When CLAMP supervised those 'xxxHolic' ONAs, they felt more authentic than some filler arcs in the main series.

The question of whether 'ona' anime episodes are canon can be a bit tricky, and it really depends on the specific series and how the creators define their own continuity. ONA, or Original Net Animation, refers to anime that's released directly online rather than through traditional TV broadcasts or theatrical releases. Because of this, ONAs often have more flexibility in terms of storytelling—sometimes they're side stories, sometimes they're full-fledged sequels or prequels, and sometimes they're just fun little extras that don't really tie into the main plot. For example, the ONA episodes for 'Attack on Titan: No Regrets' delve into Levi's backstory, and while they aren't part of the main manga, they're considered canon because they were supervised by the original creator, Hajime Isayama. On the other hand, some ONAs, like the comedic shorts for 'The Disastrous Life of Saiki K.', are clearly non-canon and just for laughs. It really comes down to whether the original author or studio confirms them as part of the official story. If you're curious about a specific ONA, checking interviews or official statements from the production team can clear things up. Personally, I love how ONAs can expand a universe in unexpected ways, even if they aren't always essential viewing.

The side stories in 'Omniscient Reader's Viewpoint' (ORV) are absolutely fascinating! From what I've gathered diving deep into forums and discussions, the consensus seems to be that while they aren't *directly* tied to the main plot's progression, they enrich the world-building and character backstories in ways that feel intentionally complementary. For instance, the 'Twilight Fragments' side story expands on Dokja's relationships with side characters in a way that retroactively adds emotional weight to certain main-story moments. That said, the authors (Sing-Shong) have a knack for weaving subtle threads between main and side content—like how some side stories reference 'hidden scenarios' that later gain relevance. It's less about strict canonicity and more about layers of storytelling. Personally, I treat them as 'soft canon': not mandatory, but rewarding for those who want the full tapestry of ORV's universe.

OVAs are such a fascinating gray area in anime! From my experience, whether they're canon really depends on the series. Some, like 'Attack on Titan: No Regrets,' tie directly into the main plot and even adapt bonus manga chapters, making them essential viewing. Others, like many 'Naruto' OVAs, are pure filler—fun little side stories that don’t impact the overarching narrative at all. Then there’s the murky middle ground. Take 'Death Note: Relight.' It’s a recap film with new scenes that slightly alter the ending. Some fans treat it as semi-canon, while others ignore it entirely. Studios rarely clarify, leaving us to debate endlessly. Personally, I love digging into production notes or creator interviews for hints. It feels like solving a puzzle, though sometimes the answer is just 'enjoy it for what it is.'

From what I've seen, OADs can be a mixed bag when it comes to canon. Some tie directly into the main storyline, adding depth or filling gaps—like the 'Attack on Titan' OADs that explore Levi's backstory, which absolutely feels essential. Others, though, are just fun side stories or alternate scenarios that don't impact the core plot at all. I remember watching the 'My Hero Academia' OADs and realizing they were more like bonus adventures than anything plot-critical. It really depends on the series. For something like 'Fate/stay night,' the OADs often adapt material from the original visual novels that didn't make it into the main anime, so they feel more canonical. But then you get shows where the OADs are clearly non-canon gag reels or beach episodes. If you're a completionist, they're worth watching, but if you're tight on time, checking fan forums or wikis to see which ones 'count' might save you some hassle.
