Huaxu Final Chapter "Soten no Hen" Begins Distribution on Tuesday, April 7!

In "Soten no Hen," where the story of the Huaxu arc reaches its climax, the genius Karakuri master "Sui" makes her appearance in an exclusive mecha costume! A teaser video for the theme song and various events will also be released simultaneously.

■ New Area "Kokyo" Unlocked! Main Story "Asking the Azure Sky as the Great Wind Rises" Commences

The mystery surrounding Huaxu is finally nearing its core. As the "Bokyo no Gi" (Incense Offering Ceremony) begins and the Celestial Tomb appears, Shiryu moves alone. Is his true intention that of an ally or an enemy? Amidst uncertain circumstances, the protagonist challenges the two dragon gods, "Taikou" and "Shokuin," to a decisive battle.

In "Soten no Hen," Huaxu's capital, "Kokyo," will be unlocked as a new adventure stage. In contrast to the lush natural scenery of "Entsuto," areas where you can enjoy the unknown aspects of Huaxu will appear one after another, such as "Kokyo Inner City" with towering dragon statues, "Shoran Village" with tranquil rural landscapes, "Sangaizan" where the secrets of Karakuri techniques lie, and "Taikeiryo" filled with mysterious light.

A 19-year-old genius Karakuri master responsible for material management in "Sangaizan," the rebel organization of Huaxu. While saying, "It's you again... I guess it can't be helped," she works tirelessly for her comrades, a true unsung hero. Despite her small stature, she sometimes speaks with an air of importance, but at her core, she is kinder than anyone. What she fears most is being told, "We don't need Sui anymore." Her hidden goal is to restore the honor of her benefactor, who was falsely accused.

What is "Duet Night Abyss"?

✦ All Characters and Weapons FREE! Break the "Ceiling" of RPGs!
This title overturns the conventional wisdom of traditional social games, completely abolishing character gachas, weapon gachas, and stamina systems. You can acquire characters for free through gameplay, and weapons can also be obtained for free through the crafting system. Most content can be enjoyed without in-app purchases.

✦ Two Protagonist Perspectives × Multi-Angle Story
The story takes place on a continent where magic and machinery coexist. Players take on the roles of two protagonists with completely different backgrounds and positions, meeting various companions, fighting to survive, and experiencing the story from two perspectives.

✦ Free Weapon Configuration × All-Direction Exhilarating Battle
A highly flexible weapon system where all characters can wield all weapons, and exhilarating battles that allow for 360° all-directional action. You can experience the exhilaration of being freed from gravity with free and stylish movements like parkour.

✦ Cultivation System "Demon's Wedge" That Unlocks Potential
With the special cultivation system "Demon's Wedge," you can strengthen and customize your character's skills and combat motions to suit your preferences and playstyle. Notably, the "Demon's Wedge" obtained through "Request" quests uses a fixed numerical system and can be used in common for all characters and weapons. This significantly reduces the cost of sifting through random elements and repeated grinding, allowing for a more comfortable gameplay experience.
