If you enjoyed the recent crossover with the webtoon "Return of the Blossoming Blade," Netmarble has just launched a fresh collaboration event in Seven Knights Idle Adventure. This update introduces Biya alongside a series of limited-time summer-themed activities.
This marks the second partnership with the renowned illustrator and cosplayer, bringing two new Legendary heroes—Mariner Biya and Hellenia (Swimsuit)—into the RPG.
With the latest version of Seven Knights Idle Adventure, you can dive into the Hot! Special Summer Check-In event, running until July 23rd. Notably, Mariner Biya is available as a free reward simply by logging in daily to collect bonus items.

Meanwhile, the Hot! Summer Festa: Seaside Dungeon challenges you to clear stages and earn event coins. These coins can be exchanged for rewards like the Summer Festa Hero Summon Ticket. Also available is Elke's Cauldron Event, where you gather event materials to redeem a Summer Festa Event Summon Ticket until July 23rd—plenty of time to participate.
