The tagline for the collaboration is "Seikimatsu Kyūseishu Densetsu," which is a pun. It normally means "Legend of the Savior of the Century's End," a reference to one of Kenshiro's titles, but in this case one of the characters has been swapped out for the kanji for alcohol. Instead it reads "Legend of the Saving Wine of Century's End.“
