The Fourth Boundary Launches Apparel Brand 'The Fourth Boundary'! Outerwear Designed by Kai Mochizuki Also Confirmed

The creator collective The Fourth Boundary, behind the ARG 'Everyday Erosion Game,' is pleased to announce the launch of the first season collection of its apparel brand 'The Fourth Boundary,' now open for pre-orders.

'The Fourth Boundary' is an apparel brand that expands the universe of The Fourth Boundary.

Staff and Interstitial Agents of The Fourth Boundary

While the weavers, who are staff members of The Fourth Boundary, wear 'white,' the 'black' worn by interstitial agents symbolizes those who walk the boundary and exist between two worlds.

What 'The Fourth Boundary' proposes is not special equipment or uniforms detached from daily life. It is clothing designed to blend into the streets as everyday wear, yet quietly bring forth the silhouette of the 'interstitial agent' within the wearer.

Through silhouettes, textures, and details, multiple senses are interwoven to signify that the wearer is an 'interstitial agent.'

Now, for the first time, key visuals of 'The Fourth Boundary' and its interstitial agents, illustrated by artist Kai Mochizuki, have been unveiled. Additionally, the production of the outerwear worn by the interstitial agent in the illustration has been confirmed.

Alongside the launch of 'The Fourth Boundary,' The Fourth Boundary's official Instagram account has also been launched.
