The environmental mystery label 'MARGINE', developed by Mirai Accelerate LLC, will begin selling the ARG-style puzzle-solving experience kit 'The Story Beginning from a Teahouse in Akizuki', set in Akizuki, Asakura City, Fukuoka Prefecture, on BASE for 2,500 yen (tax included).
You can get to know Akizuki deeply without visiting the site, and the more you know, the more you will want to go—it is a completely new way of encountering a region where story and history intersect.
■ [An Experience That Seemed Like It Existed, But Didn't]
From the moment you hold the kit, you are drawn into the story.
Following the enclosed map and letters, enter the world of Akizuki where digital and real intersect. The experience of tracing a certain 'memory' carved into the history of the Akizuki clan, in cooperation with the teahouse VTuber 'Akizuki Miihi', is neither a tourist guide nor a history textbook.
The feeling that the town of Akizuki begins to breathe within you little by little every time you solve a puzzle—that is the puzzle-solving of MARGINE.
■ About the Story
A memory related to a certain family heirloom passed down in the lineage of a former Akizuki clan samurai. It is a story where the teahouse VTuber 'Akizuki Miihi' traces that memory with the player to find the 'feelings' hidden within the history and culture of Akizuki.
It is content that people of all ages can enjoy with peace of mind, without any negative elements. Please pick up the kit to enjoy the details of the story.
