The Slitterhead Concept Art Exhibition—originally held in July 2025 in Ginza, Tokyo and met with enthusiastic response—will now open in Osaka’s Nipponbashi district. Titled “The Concept Art of Slitterhead in Osaka,” the exhibition begins on Saturday, November 8, 2025.

In addition to the original merchandise scheduled for sale at the Shinjuku POP-UP STORE “MongTsui Night Market,” the Osaka venue will feature exclusive items available only at this exhibition. On opening day, November 8, a special talk event with director Keiichiro Toyama—complete with drinks—will offer a closer, more personal look at his creative process.

The exhibition will showcase a wide range of previously unreleased concept materials: early rough sketches, design documents for Echoes of Love Society, the mysterious cult that plays a key role in the story, and even plans for “Human Farm,” a concept ultimately not implemented in the final game.
One of the highlights is the never-realized “fourth boss,” Harley. With character design by Tatsuya Yoshikawa and creature design by Keisuke Yoneyama, the exhibition reveals Harley’s full visual evolution—from human disguise to its “complete form.”

A must-see special exhibition that delves into the deepest layers of Slitterhead. Don’t miss it.
