Demon Blade Guide Hub

Demon Blade is a Demon Slayer-themed Roblox action RPG from DemonCube, a verified Roblox group, where players choose to become a demon or a demon slayer. Every figure on this page comes from Roblox's own public API rather than a tracker's paraphrase, and each one is stamped with the moment we read it. At 13:40 UTC on August 17, 2026 the game was live as [🩸UPD]Demon Blade with 1,982 players in game and 226,244,929 lifetime visits.

Both links open the live JSON, so you can re-run our reading yourself rather than take our word for it — the numbers will have moved on since we read them, which is the point:

• games.roblox.com/v1/games — players in game, visits, favourites, created and updated dates, live title.
• games.roblox.com/v1/games/votes — the up and down vote counts behind the approval figure.

What These Numbers Actually Mean

Raw counts are easy to quote and easy to misread. These are the three derived figures we use internally to judge whether a game is durable, and what they say about Demon Blade.

• Favourites as a share of visits — 0.204%. This is a retention signal: how many of the people who showed up cared enough to bookmark. Demon Blade's 0.204% sits well under the 1.5% level that would signal a favourite-gated in-game reward, and the description does not mention any such reward, so we read this as ordinary retention rather than a manipulated count.
• Favourites per concurrent player — about 233 to 1. This compares the size of the returning population to the size of the room at any one moment. That figure sits inside the 150-to-300-to-1 band we treat as a durable, rotating audience rather than a short-lived spike.
• Approval at 96.5% across 727,842 votes. The vote count matters as much as the percentage — 702,558 up against 25,284 down is a settled verdict from a large sample, not a handful of early raters.

Put together: nearly three years old, still carrying a rotating audience roughly 233 times the size of its concurrent player count, a retention ratio with no sign of being gamed, and a large-sample approval rating. We are not putting an all-time platform rank on the visit count, because we did not verify one.

What Is Live Right Now

Everything below comes from the game's own description field on the Roblox API, read August 17, 2026 — first-party, not a tracker's paraphrase.

• Faction choice. The description opens by billing the game as a "Demon Slayer Adventure" and instructs players to "Choose to become a demon or a demon slayer."
• Breath and BDA rosters. The description lists a "Current 18 Breath" roster — Water I, Thunder I, Water II, Flame, Beast, Wind, Mist, Flower, Love, Flame II, Rock, Serpent, Moon, Sun, Insect, Sound, Thunder II, Sun II, Serpent II — and a "Current 16 BDA" roster — Arrow, Stain, Spider, Nightmare, Reaper, Destroy, Element, Pot, Ice, Black Thunder, Biwa, Blood, Wolf, Bewitchment, Reaper II, Demon King. We reproduce both lists as written and are not expanding "BDA" or explaining how either roster is unlocked, because the description does not say.
• Secret Traveler. The description states a "Secret Traveler" spawns in the map every hour.
• Latest patch note. The update line reads "New Breath: Blood BDA rework!" verbatim. The description does not clarify whether Blood is being added as a new Breath or reworked as a BDA — "Blood" appears in the BDA list above, not the Breath list — and we are leaving that contradiction exactly as written rather than resolving it ourselves.
• Live codes named by the developer. The description lists three codes directly: DEMONBLADE for "+3 Reset States, +5 Race Spins", DEMONBLADE300 for "+5 Race Spins, +100,000 Money", and DEMONBLADE500 for "+10 Race Spins, +100,000 Money". Our codes page lists DEMONBLADE's reward slightly differently — "5 Race Spins and 3 Stat Refunds", sourced to a tracker — which matches the developer's quantities but not the developer's own wording of "Reset States"; we flag that rather than pick one term.
• Milestone code. The description promises "800K Likes for New CODE." The votes endpoint above shows 702,558 up-votes at this reading, 97,442 short of that threshold, so the milestone code cannot exist yet — any list offering one today is publishing something the game has not reached.

The description does not name an event beyond the roster update and the Secret Traveler, so that is where this section stops.

Background

Demon Blade launched on October 9, 2023 — about two years and ten months before this reading — and the most recent developer update the platform recorded was August 14, 2026, three days before we read it. Across that span it has accumulated over 226 million visits, which averages out to roughly 216,900 visits per day of its life, though real traffic is far from evenly spread. We could not source a date for when the code system itself began, so we are not stating one.

The developer's description carries no anti-cheat or photosensitivity warning, so unlike some other Roblox hubs we cover, we have nothing first-party to report on that front.

How the Game Works

Demon Blade is a Demon Slayer-themed action RPG: players choose to become a demon or a demon slayer, and the developer's own description names a roster of 18 Breath styles and 16 BDA styles currently available in the game. Servers hold up to 12 players. That is the honest limit of what we can state. We have not played the game and we are not describing how the Breath or BDA rosters are unlocked, how the demon-versus-slayer choice changes play, or what a Race Spin or a Reset State actually does beyond the reward text quoted above — none of that is in the developer's description, so it does not go on the page.

Official Channels

Where to go for first-party information. We link these without nofollow because we have checked them and we do stand behind them, unlike the third-party trackers we cite on the codes page.

• Demon Blade on Roblox — the game itself, and the description field that most of this page is sourced from.
• DemonCube — the verified developer group behind the game.

The description invites players to "Join our community for updates, codes, and more!" but does not link a Discord or social account, so we have nothing further to point to here. The raw API endpoints behind our figures are linked in the Live Snapshot section above rather than here, because they are a verification tool rather than somewhere a player would go.

Codes

Demon Blade's own Roblox description names three active codes directly — DEMONBLADE, DEMONBLADE300 and DEMONBLADE500 — and our codes page adds a fourth, BLOODREWORK, sourced to three independent trackers. Codes are redeemed through the gear icon in the top-left corner of the screen, not a menu button. Full detail, sources and the open reward-wording dispute are on the codes page.

Update Rule

We do not mark a code as active just because another page says it is active, and we do not quote a player count without saying when we read it. This page records what was checked, when it was checked, and where the evidence runs out.
