Smilegate participated in Anime Expo, North America's premier subculture festival held at the LA Convention Center from July 2 to 5 (local time), showcasing 'Miraesi' and 'Chaos Zero Nightmare.' The company engaged with fans on-site through various events, including demo stations, immersive booths, and photo zones featuring cosplayers. During a panel talk by Super Creative, the developer of Chaos Zero Nightmare, some details regarding Season 4 were unveiled.

The upcoming Season 4 update, titled 'Broken Light and Claws,' is set to launch on July 28 and will begin to shed light on the story of the cosmic gods associated with the new 'Flash' mechanic. Alongside this announcement, three new combatants—Hilde, Arabella, and Olga—were introduced.

Hilde is a member of Iron Rain, like Luke and Beryl, and serves as the leader of the 'Fox Squad.' Unlike most Iron Rain combatants who typically use heavy weaponry, she wields a massive bow as her primary weapon and is equipped with a suit that emphasizes mobility and tactical movement.

Arabella is the leader of the notorious mercenary group 'Black Spica,' to which Veronica also belongs. Her design is themed around a dangerous and precarious allure, and she fittingly uses a sword-whip as her primary weapon. The final character introduced, Olga, wields a giant scythe and possesses the ability to manipulate steel at will. She is also a key character who will play a central role in the unfolding story involving the cosmic gods.

The 'Casual Outfit' system, which will be added in Season 4, was also unveiled. This is a skin system that changes a character's appearance, complete with dedicated voice lines and stories tailored to each outfit. When equipped, these skins are applied not only to general content but also within the Ark City. 'Full party' casual outfits are being prepared for the new Season 4 characters. For existing characters, upcoming additions include Heidemarie's beach cafe uniform, Sereniel's swimsuit, and the disguises worn by Tiphera and Rita in the Season 2 story.

Meanwhile, Chaos Zero Nightmare will hold a three-week pre-season following the end of Season 3 on July 8. This pre-season will introduce 'Fei,' a Void-attribute Ranger previously released on the CN server, and will also feature a revamp of the Act 1 story based on user feedback. Further information regarding future seasons of Chaos Zero Nightmare can be found on the official community.
