TOKYO – The inspiration for a new menu item at Japanese convenience store chain Circle K Sunkus is courtesy of American rock-and-roll band KISS.

The Wall Street Journal reports that the Geki-kara (extra spicy) Chili Tomato Man bread will go on sale February 24 at the convenience stores. Bamboo charcoal baked into the buns give it a black color, while the tomato-based sauce inside is made “hotter than hell” with red peppers and jalapeno powder.

“The product was made spicy inspired by the hard rock music performed by KISS,” a spokeswoman for Circle K Sunkus told Japan Real Time.

KISS begins touring in Nagoya on February 23 and finishes up in Tokyo on March 3. Circle K Sunkus Co. is selling the black-colored, spicy steamed bread for a limited time to celebrate the band’s 40th anniversary and five shows in Japan.
