Gang King Vol. 18 (Kodansha, 2024)

Jimmy and Belo arrive at the battleground between Bara High and the Workmen, and decide to settle the score by one-punch rules: Each of them takes turns punching the other until either of them can't stand back up. Watching two of their generation's strongest fighters duke it out, the two gangs cheer their leaders on with all their hearts. As the punch-out intensifies by the moment, the two leaders take this chance to speak to their respective members from the heart.
