■ Concept Art Exhibition “The Concept Art of Slitterhead” in Osaka

The highly praised “Slitterhead” concept art exhibition, which previously took place in Ginza, Tokyo this July, has now been confirmed for Osaka!
Titled “The Concept Art of Slitterhead in Osaka,” it will begin on November 8, 2025.
In addition to merchandise available at the Shinjuku pop-up store “Wangzui Night Market,” exclusive items made specifically for this Osaka exhibition are also planned.
Furthermore, a special talk show titled “A Night Drinking with Keiichiro Hayaishi” will be held on opening day (November 8), where attendees can enjoy more personal insights from the director over drinks.

Featuring never-before-seen concept materials—from rough early designs to detailed sketches of the mysterious religious group “Aimeikai,” which radiates an eerie presence within the story, and even speculative concepts like the unreleased “Human Ranch” that were not included in the final game—this exhibition offers a rare glimpse into the deeper layers of Slitterhead.
Among these highlights is the unrealized fourth boss character, “Harley.” Character designer Tatsuya Yoshikawa and creature designer Keisuke Yoneyama will reveal visual materials tracing Harley’s evolution—from human disguise to its full “true form,” showcasing its complete design.

An exclusive exhibition for fans seeking deeper insight into Slitterhead. Don’t miss this must-see event!
