From Wednesday, November 5, 2025, the POP-UP STORE “MongTsui Night Market” will open at Kinokuniya Shinjuku Main Store.
The event will feature original merchandise using newly created illustrations by ULTTiVO—the creative unit that includes illustrator superlog. Visitors can also enjoy exclusive items inspired by “Kowlong,” a chaotic city inhabited by Slitterhead, grotesque creatures that disguise themselves as humans and devour their minds.

On Saturday, November 15, a special talk event will be held with director Keiichiro Toyama, producer Kazunobu Sato, and Naoko Sato, the scenario writer known for her work on the SIREN series.

This POP-UP STORE is part of a special celebration marking the first anniversary of Bokeh Game Studio’s debut title, Slitterhead, created by Toyama. Don’t miss this commemorative event.
