Inven Global

On Thursday, October 1, the Demon Slayer: Kimetsu no Yaiba collaboration launched in Seven Knights Re:BIRTH. Running through October 29, the collaboration offers new heroes, pets, and equipment alongside exclusive playable content. In the Part 1 update released today, Tanjiro Kamado and Zenitsu Agatsuma appeared as Attack-type heroes.

The core of Tanjiro's kit is his passive skill, Hinokami Kagura. Upon death, he revives in an Unyielding state, which grants him Transparent World, giving piercing to all attacks and increasing Weakness Attack Chance by 100%. At Transcendence Level 2, the recovery amount of Unyielding hit counts upon enemy defeat increases, and at Transcendence Level 6, Transparent World is applied from the start of battle. He also provides Attack-type allies with Effect Hit Chance increase and a delayed buff that grants Damage Immunity and Physical Attack increase upon expiration, while inflicting Physical Vulnerability on enemies.

His basic attack can inflict Burn on a single target. Skill 1, Hinokami Kagura: Dance, deals additional damage to 3 enemies based on their number of buffs, while Skill 2, Hinokami Kagura: Dance Flash, removes buffs from all enemies and inflicts additional damage based on their number of debuffs. Skill enhancement adds Ignore Defense and Block Rate Reduction, respectively.

Zenitsu's passive skill, Thunder Breathing, provides Blessing and a Shield; when afflicted with Crowd Control, it cleanses the debuff and grants Crowd Control Immunity. At Transcendence Level 2, cleansing triggers a 26-second skill cooldown reduction and an additional Shield. He also grants Attack-type allies a 21% increase in Critical Hit Chance and decreases enemy Effect Resistance.

Skill 1, Thunder Breathing First Form: Thunderclap and Flash, deals piercing damage to a single target and triggers a consecutive cast up to 1 time upon defeating an enemy. Skill 2, Thunderclap and Flash Eightfold, reduces turn-based buffs on all enemies by 2 turns before attacking. When enhanced, both skills gain Ignore Defense, and at Transcendence Level 6, an Electrify effect is added. Along with Blessing, he comes equipped with the powerful option of consecutive skill triggers.

Awakened Tanjiro features increased basic attack damage and Burn chance, with Burn inflictions added to each attack of Skill 1 and Skill 2. Skill 2 also gains an effect that resets his skill cooldowns whenever an enemy is defeated. The Ignore Defense for Skill 1 and Block Rate Reduction for Skill 2—previously gained through skill enhancement in his base form—are applied as innate default effects in his Awakened form.

His Awakening Skill, Hinokami Kagura: Setting Sun Transform, deals 4 hits of damage to a single enemy and triggers a consecutive cast at equal power up to 1 time if it defeats an enemy. When enhanced, it grants Attack-type allies All Damage Immunity and a delayed buff.

Awakened Zenitsu gains a chance to remove buffs on his basic attack, 3-buff removal on Skill 1, and Defense Reduction on Skill 2. His passive gains a 25-point Awakening Gauge increase when Crowd Control cleanse triggers, and his Critical Hit Chance buff for Attack-type allies increases from 21% to 25%. The Ignore Defense for both skills, previously obtained via skill enhancement in his base form, becomes an innate default in his Awakened form.

His Awakening Skill, Thunder Breathing Seventh Form: Honoikazuchi no Kami, deals 2 hits of damage ignoring 65% Defense to the 2 enemies with the highest Attack, executing targets with 26% or less HP. However, execution does not trigger if the target's current HP exceeds 120% of the caster's Attack power. Skill enhancement adds a 2-turn reduction to turn-based buffs, and Transcendence Level 6 adds an Electrify effect to each attack.

The new Legendary pet, Nezuko Kamado, increases all Attack, Defense, and Max HP for Demon Slayer faction allies. A total of 4 copies of Nezuko can be obtained through events: 1 copy each from completing 150 hero summons in the Demon Slayer Corps Special Duty event and completing 1,000 fodder farming runs, with 2 more exchangeable at the Demon Slayer Corps Supply Depot. This allows players to develop her up to 6-Star rank. Collaboration equipment such as Nichirin Swords is also included among event rewards.

The Trial of Infinity is a 10-floor content mode accessible after clearing Floor 50 of the Tower of Infinity. It has no separate entry limit, with Akaza appearing as the boss on Floor 5 and Doma appearing on Floor 10. Players can adjust the difficulty on each floor by choosing buffs and debuffs, and the number of achievement medals earned varies based on the selected conditions. In essence, the existing Tower of Trial has been transformed into the Trial of Infinity to mark the collaboration.

Rewards are provided based on first-time floor clears and cumulative achievement medals earned. Clearing a floor for the first time grants 5 Hero Summon Vouchers, while medal milestones award Rubies, Tuning Crystals, Exclusive Equipment Wish Summon Vouchers, and more. Reaching 50 medals yields a 4-Star Legendary Accessory Box, while 60 medals offer 1,500 Rubies, 3,000 Inner Embers, and other rewards.

The Demon Slayer Event Dungeon is accessible after clearing Adventure 2-5, with Part 1 unlocking on October 1 and Part 2 on October 15. Entry tickets recharge by 5 each day up to a cap of 5, and up to 5 additional tickets can be purchased per day for 100 Rubies each. Earned Grilled Miso Rice Balls are used in the Event Shop. Both the Trial of Infinity and the Event Dungeon run until maintenance on October 29.

Novice Arena opens for players who unlock Arena content after the October 1 maintenance. Basic rules and entry currency are identical to Standard Arena; upon initial entry, players undergo 3 seasons (including the ongoing season) before being integrated into Standard Arena. Upon integration, tier rank and points are reset, but team formations are retained, and uncollected rewards are delivered to the mailbox. Players who reach Platinum III in Novice Arena can also apply for Total War.

Free Sweep has been added to Advent Expedition: God of Destruction. Entry currency is consumed, with the first sweep calculated at 95% of the all-time high score, and subsequent sweeps calculated at 90% of the previous sweep's score. If players manually play and set a new personal record, they can sweep again at 95% of the new high score. Repeat sweeps are allowed as long as entry currency is available, and high scores persist even when changing guilds.

At the Accessory Rental Shop, players can rent 6-Star +15 enhanced High-Grade Ring of Resurrection, High-Grade Ring of Immortality, and High-Grade Ring of Authority for 1,000 Rubies each. Up to 3 rentals can be used per week regardless of type, expiring every Thursday at 9:00 AM regardless of purchase timing. Renting yields mileage that awards a Legendary Accessory Box. Players lacking Legendary Accessories should consider taking advantage of rentals with Rubies.

Changes have also come to Real-Time Arena. Held on Tuesdays, Fridays, and Sundays, 5 entry tickets recharge at 9:00 AM on active days, and entry is impossible without tickets. On active combat days, up to 15 additional tickets can be purchased daily using Gold, with held tickets and weekly rewards resetting every Monday at 9:00 AM. A total of 1,000 free Rubies can be earned as weekly rewards for reaching 1, 3, and 5 wins.

Total War adds a Mythic tier at 8,000 points, alongside buffed High-Grade Total War Coin rewards. Attention is on whether these updates will ease the burden of Total War, which recently drew critique for a steep difficulty jump. High-Grade Arena shifts to a 5v5 mode, while Castle Rush and Advent Expedition: Shadow of Destruction receive once-per-account milestone rewards based on combined top scores. Guild War gains a flag feature to declare attack intent and a mock battle function utilizing enemy defense team data.

Players can now hold up to 2 copies of identical Exclusive Equipment, with duplicate gains beyond that converted into 500 Tuning Crystals. After tuning, players can choose between the options from before or after tuning. Limited-time Exclusive Tuning Crystals for specific heroes have also been added; collaboration hero currencies can be used until maintenance on October 29, converting to standard Tuning Crystals at a 20:1 ratio upon expiration.

In addition, Advent Expedition kill and ranking rewards have been adjusted, the unlock condition for Melcure's Lab has been relaxed to Nightmare 5-10, and the default medal setting when entering Tower of Trial has changed from 3 to 1. Notification Center and equipment management user-experience enhancements were also applied. Carl Heron's "Guide of Duel" costume was added; upon Real-Time Arena season end, players ranked Master III or higher receive the Rare grade, while Platinum III through Diamond I earn the High-Grade version. The claim period runs from after maintenance on November 12 until before maintenance on November 26.

The Demon Slayer Corps Check-In Event runs for 7 days, allowing players to collect rewards simply by logging in. Day 1 provides a 6-Star Tanjiro, Day 3 awards a 6-Star Zenitsu, and the final day grants 1,000 free Rubies. In the Hero Growth Event, players can earn Collaboration Summon Vouchers, growth materials, and exclusive Nichirin Sword equipment based on their Tanjiro and Zenitsu progression levels.

The Demon Slayer Corps Supply Operation allows players to collect Wisteria Flower Coins from repeat battles and Raids to exchange for Nezuko, collaboration equipment, Awakening Stones, and more. The Demon Slayer Corps Special Duty event progresses through repeat battles, summons, Growth Dungeons, Raids, and Arena; completing 1,000 repeat battles and 150 hero summons awards a 4-Star Nezuko for each milestone. The Supply Depot is open until 4:59 AM on October 29.

The Trial of Infinity offers Summon Vouchers, Rubies, Tuning Crystals, Legendary Accessory Boxes, and more based on floor clears and cumulative medals. A separate Challenge Event awards collaboration equipment and a 6-Star Rare Accessory Selection Box for meeting floor medal requirements. A surprise Push Event is also underway, allowing players who log in before 5:59 PM on October 25 to claim rewards unlocked sequentially from October 1 to 7, including 20 Collaboration Summon Vouchers and 10 Awakening Stones.

There is also the Event Dungeon. By enjoying this content and collecting Grilled Miso Rice Balls, players can exchange 250 currency per piece for the exclusive equipment of both heroes, with Name Cards, Frames, Shining Skill Enhancement Stones, and more available in the shop. Since players can now hold up to 2 pieces of Exclusive Equipment per hero, securing Tanjiro and Zenitsu's hero equipment allows them to swap setups based on content needs.

In addition, be sure not to miss other events, such as a coupon event where players search for hidden hints in the in-game lobby, the "Find the Demon Slayer Corps in the Infinity Castle!" event where players earn rewards after checking notice images, and a PV video milestone event tied to the official YouTube channel.
