Battle Tendency - Chapter 21 
Ultimate Warriors from Ancient Times, Part 1 (太古から来た究極戦士 その① Taiko kara Kita Kyūkyoku Senshi Sono 1), originally The Truth That Hides in the Mouth of Truth (真実の口にひそむ真実 Shinjitsu no Kuchi ni Hisomu Shinjitsu) in the WSJ release, is the twenty-first chapter of Battle Tendency and the sixty-fifth chapter of the JoJo's Bizarre Adventure manga.
After Caesar flamboyantly sits down at a table, he and Joseph start up a game of poker. Both end up cheating and start to argue aimlessly until Speedwagon interrupts to ask why they've been waiting around for 8 hours. A moment later, a car arrives to take them to the other Pillar Men. Caesar explains that he had formed an alliance with the Nazis due to their common interest in the Ripple and in finding a way to defeat the Pillar Men. He introduces the driver as a young German soldier named Mark, who is betrothed to his girlfriend and planning to marry in the following week.
The group arrives at the famous tourist attraction, "The Mouth of Truth", which serves as a secret entrance into the Pillar Men's resting place. Upon entering, they stumble upon the corpses of the other Nazi soldiers, which puts Mark in a panic. Suddenly, the Pillar Men appear, walking towards Mark, who does not have enough time to react as Wamuu walks straight into him, absorbing a large portion of Mark's body without noticing, causing Mark to experience immense pain.
