Seven Knights Re:Birth is launching its collaboration with Demon Slayer: Kimetsu no Yaiba on Thursday, October 1. Tanjiro Kamado and Zenitsu Agatsuma will be the first to arrive, followed by Giyu Tomioka and Shinobu Kocho joining on October 15. All four heroes are Special Legendary grade—often called "True Specials" by players—and players who log in and play consistently during the collaboration period can acquire all four heroes, four types of exclusive weapons, and the Nezuko Kamado pet for free.

On the official broadcast "May's Breaking News: Collab Summary," skill animations, battle characteristics, acquisition methods, and exclusive content for the four heroes were revealed. The presentation highlighted each character's distinct combat style reflecting their unique traits: Tanjiro becoming stronger after overcoming crises, Zenitsu focusing firepower on single targets, Giyu building strength through offense and defense, and Shinobu accumulating and spreading poison.

Tanjiro, Zenitsu, Giyu, and Shinobu, who arrive with the collaboration, can all be acquired through regular gameplay. Executive Producer Son Geun-hee stated, "This decision was made with the hope that more adventurers will join Seven Knights Re:Birth through this collaboration." By playing consistently throughout the event period, players can obtain all four heroes, their respective exclusive weapons, and the Nezuko pet. Detailed event information will be made available through future official announcements and in-game notices.

Tanjiro and Zenitsu, appearing in the first update, are both Attack-type heroes, but they excel in different ways during battle. While Tanjiro is a comeback dealer who boosts his firepower after surviving a crisis, Zenitsu serves to quickly neutralize key enemy heroes with powerful single-target attacks.

When Tanjiro's HP falls low during battle, his potential awakens and his combat power increases. Once he survives a crisis, both his offensive ability and survivability are enhanced simultaneously. The development team explained that they focused on enabling him to turn the tide of battle with strong late-fight firepower, preparing him for use in both PvE and PvP.

Zenitsu focuses on burst damage and single-target control. The core of his kit is the ability to cast powerful single-target attack skills multiple times, taking down key enemy heroes quickly to shift the momentum of battle. The developers stated that he was designed as an ace capable of cutting off the enemy's main forces. The animations for his skills, including Thunderclap and Flash, reflect his signature fast and powerful attacks.

The second update will feature Water Hashira Giyu Tomioka and Insect Hashira Shinobu Kocho. Giyu is prepared as a Universal type who powers up by cycling through offense and defense, while Shinobu is a Magic type who accumulates and spreads poison. The key to Giyu's kit is accumulating offensive and defensive stacks. He gathers power not only when attacking enemies but also while enduring incoming hits. As combat continues, fulfilling certain conditions allows him to enter an empowered state.

Supporting this mechanics is high damage reduction. Since he must withstand enemy attacks while building power, he possesses high damage mitigation. The developers explained that he was designed to shine brighter as fights drag on, introducing a combat style tailored for prolonged battles alongside skill animations utilizing the flow of water.

Shinobu appears as a Magic-type hero. Reflecting her characteristics from the original work of utilizing thrust attacks and poison, she focuses on stacking damage over time rather than landing a single heavy hit. Players will make use of a unique stacking mechanism as she stacks and spreads poison.

The development team explained that they brought out Shinobu's signature trait from the original work—compensating for her physical stature with poison. Skill names featuring the word "Dance" and her dazzling movements were mentioned on stream, showcasing a combat concept centered on pressuring enemies with poison. Notably, a hint was provided that she will possess a poison stacking mechanism that cannot be easily cleansed by debuff removal.

Trial stages where players can test out collaboration heroes directly and the tower-climbing content "Trial of Infinity" are being prepared. Upper Rank demons Akaza and Doma from the original work will also appear as bosses. In the trial stages, players can try out collaboration heroes they have not yet acquired. Week 1 unlocks trial stages for Tanjiro Kamado and Zenitsu Agatsuma, while Week 3 opens trial stages for Shinobu Kocho and Giyu Tomioka, aligned with their hero release schedules on Thursday, October 1 and Thursday, October 15, respectively.

Akaza will appear as a boss in Week 1, and Doma in Week 3. The developers explained that each stage features four difficulty levels, with higher difficulties yielding greater currency rewards. The structure allows players to test collaboration heroes while engaging in boss battles across different difficulty levels.

Trial of Infinity is tower-climbing content similar to Tower of Trial. Akaza appears as the 5th floor boss, and Doma as the 10th floor boss. The video introduced the placement of both bosses and the basic structure of the mode, noting that detailed progression rules and rewards can be checked through update announcements and in-game.

A dynamic day-and-night cycle will be applied to the collaboration-exclusive lobby. Based on the user's device clock, the atmosphere of the lobby will shift according to real-world time. During the broadcast, the host expressed particular fondness for the night background. The development team explained that this feature was created to give players an enjoyable visual variation every time they log in. Detailed event information not revealed during the broadcast will be disclosed through future official announcements and in-game.
