Event Details: Step into the Game
The “Tonari no Bukeya” event is designed to bring the digital realm of “Duet Night Abyss” to life, offering a tactile and engaging experience for its growing fanbase. The event features several activity corners, reminiscent of a traditional Japanese festival fair (ennichi), where visitors can test their skills and luck to win unique prizes.
-
Rin’s Training Ground: Participants can join Rin’s shooting training. With five shots, hitting just one target guarantees a random acrylic stand from a selection of four, along with a gachapon lottery ticket.

-
Maggie’s Treasure Hunt: Grab a shovel and embark on an exciting treasure hunt! Finding a specified gem within a 30-second time limit earns a random can badge (one of four designs) and a gachapon lottery ticket.

-
Rebecca’s Fluffy Challenge: A playful twist on the classic Japanese super ball scooping game. Using a poi (paper scooper), players have 30 seconds to scoop multiple super balls to win a weapon-themed keychain and a gachapon lottery ticket.

Each mini-game offers a gachapon lottery ticket as a participation prize, leading to the Gachapon Lottery Corner. Here, accumulated tickets can be used for a chance to win even more exclusive items:
-
First Prize: Duet Night Abyss Gift Box (1 item)
-
Second Prize: Fina Mouse Pad (1 item)
-
Third Prize: Sticker Set (1 item)

For those who enjoy a mental challenge, the Mystery Challenge invites participants to solve a crossword puzzle using hints scattered around the venue. The first 100 clearers each day will receive a “Luna Tribe Hammer Plush Pillow.”

About Duet Night Abyss: Redefining RPG Freedom
“Duet Night Abyss” is an action RPG that challenges conventional mobile game models. It notably abolishes character and weapon gacha systems and stamina requirements. Players can acquire characters and weapons freely through gameplay and a crafting system, allowing for a largely free-to-play experience. Set in a continent where magic and machinery coexist, the narrative unfolds from the perspectives of two protagonists with vastly different backgrounds. This dual viewpoint offers a rich, multi-angled story as they meet various companions and fight for survival. The game also boasts a highly flexible weapon system, allowing any character to wield any weapon, combined with 360-degree exhilarating combat. Its parkour-like movement system offers a sense of freedom and gravity-defying action.
A unique “Wedge of Demon” growth system allows players to customize and enhance character skills and combat motions to suit their preferred playstyle. The “Wedge of Demon” items, obtained through “Request” quests, utilize a fixed numerical system, making them universally applicable to all characters and weapons. This design significantly reduces the need for random farming and grinding, promising a more streamlined and enjoyable gameplay experience.
