Seven Knights Re:Birth x Demon Slayer: Collab Confirmed

Netmarble has confirmed Seven Knights Re:Birth's next crossover: a collaboration with Demon Slayer: Kimetsu no Yaiba, launching October 1. It's the game's second major anime tie-in following its earlier Solo Leveling collaboration, and the announcement trailer leans hard on faithful skill recreations — Tanjiro's Water Breathing forms get their own dedicated spotlight — alongside a promise that every collab character will be obtainable just by playing, not gated behind a pure gacha pull.

Character Rollout by Week

Netmarble's pre-registration page refines the rollout into two hero groups rather than a clean two-phase split:

• Kisatsutai group — Tanjiro Kamado and Zenitsu Agatsuma: available Weeks 1–4
• Hashira group — Giyu Tomioka and Shinobu Kocho: available Weeks 3–4

That means Weeks 3 and 4 overlap, with all four heroes obtainable simultaneously rather than the Hashira pair replacing the Kisatsutai pair. On top of the four heroes, Nezuko Kamado joins separately as a Legendary Pet. Netmarble's own messaging is direct about acquisition: "Just play to get all the collab characters," with logging in during the event granting the Legendary Hero Tanjiro Kamado at ☆6, and general gameplay unlocking the Legendary Pet Nezuko Kamado — no gacha pull required for either.

Pre-Registration Rewards

Players who pre-register before the collaboration launches receive 10 Summon Tickets specifically for the Demon Slayer: Kimetsu no Yaiba banner, giving early sign-ups a head start on pulling for the collab's rate-up pool once it opens.

What the Trailer Shows

The reveal trailer showcases Tanjiro executing Water Breathing techniques in a stylized combat sequence, with an on-screen disclaimer noting the gameplay shown is still under development. Zenitsu and Shinobu both get character-focused close-ups in their signature designs, and the trailer also features a demon antagonist opponent, suggesting the collaboration includes dedicated boss content rather than just adding playable heroes to the existing roster.

Availability

Seven Knights Re:Birth is available on the App Store, Google Play, Galaxy Store, and PC, and the Demon Slayer collaboration is confirmed for all platforms starting October 1.
