AltPlus Inc. (Headquarters: Toshima-ku, Tokyo; Representative Director: Takeshi Ishii; hereinafter "AltPlus") announced that a collaboration event with the suspense horror adventure game "Saya no Uta" will be held from Saturday, May 30, 2026, for its operating card RPG title "Boukyaku Zenya." Along with this, the key visual for this collaboration and the illustration of the new collaboration character "Saya" have been unveiled for the first time.
"Boukyaku Zenya" depicts a cruel yet beautiful story set in a collapsing world, where players confront a calamity called "Yushoku" and embark on a journey to challenge lost memories and fate.
And "Saya no Uta" portrays a pure and gruesome love story between a young man who falls into a desperate sensory disorder where "everything in daily life appears as hideous lumps of flesh" due to a traffic accident, and a girl named "Saya," who was the only beautiful thing he saw in that distorted world, and how he descends into madness due to that love.
The collaboration key visual released today expresses the intersection of the worldviews of both works.
Additionally, the illustration of the new character "Saya," who will appear in "Boukyaku Zenya" from this collaboration, is also being unveiled for the first time.
Please look forward to Saya's appearance depicted through this event, and the unprecedented world woven by both works.
