Look, let us be honest: Netmarble has rolled out a collaboration update featuring the anime Demon Slayer for the collectible RPG Seven Knights Re:BIRTH on the 1st.

This initial update introduces two new heroes—Kamado Tanjiro and Agatsuma Zenitsu—alongside the legendary pet Kamado Nezuko, meaning players can finally encounter these iconic Demon Slayer characters within Seven Knights Re:BIRTH. To celebrate the crossover, everyone who logs into the game during the event period will secure Kamado Tanjiro simply as a Day 1 attendance reward. Furthermore, Kamado Nezuko and Agatsuma Zenitsu can also be earned entirely through in-game play.

Alongside this, a fresh piece of content called Infinity Castle has been unveiled. Infinity Castle is a special event mode akin to the classic Infinite Tower, dishing out various rewards for every single floor cleared. On top of that, Akaza steps up as a boss monster in the event challenge stages, promising players a rather novel combat experience.

This collaboration runs in two waves across a four-week span until October 29. The second wave is scheduled for October 15, at which point the heroes Tomioka Giyu and Kochou Shinobu are set to join the roster.
