"If the world really had ended in July 1999—
Shall we go see the "End of the World" that you never knew, together?
This immersive horror installation invites visitors to experience a story crafted by B3rmuda, a creative
unit formed by novelist Sesuji, SIREN series scenario writer Naoko Sato, and film director Masaki
Nishiyama.
For LASTWONDER, this marks the company’s first exhibition project. We collaborated with B3rmuda from the
inception of the exhibition, taking part in concept development, overall creative production, visual
design for the installations, and the design of the key visual.
The exhibition evoked the tension and anticipation of the eve of 1999, guiding visitors through an
immersive space where fiction and reality intertwined under the lead of the mysterious Apocalypse Girl.
Drawing on its expertise in game entertainment, LASTWONDER embraced the challenge of exploring new forms
of artistic expression to bring B3rmuda’s narrative to audiences worldwide.
