Chapter 171

Kakyoin's Conviction (Death 13 (4) in the JoJonium release) is the one-hundred-seventy-first chapter of the JoJo's Bizarre Adventure manga. It is also the fifty-eighth chapter of Part III: Stardust Crusaders.

Summary
After Kakyoin's previous outbreaks, the group questions his sanity and wonder if he is still fit to continue the journey. Joseph decides to cook some baby food over the fire, while the baby contemplates his plan to annihilate the group in their sleep. Polnareff tries some of the baby food recipe and upon finding it delicious, tries to eat more of it to Joseph's dismay. The baby becomes angry at Polnareff, but is interrupted by the discovery of a scorpion that had crawled onto front end of his bed. Before the scorpion attacks, the baby takes out a safety pin and quickly stabs it in the blink of an eye.

Nearby, Kakyoin had been watching the entire event and immediately informs the group of the baby's unnatural actions. They decide to check the baby's basket for the scorpion, but are unable to find it, further questioning kakyoin's stability. Joseph tries to feed the baby but Kakyoin smacks the spoon away and proclaims that the baby is a stand user. He shows the others the words etched into his arm as proof, but instead of believing him, they think that Kakyoin was the one who harmed himself. Fearing his credibility at stake, Kakyoim decides to attack the baby head on using Heirophant Green. Before he's able to act, Polnareff comes from behind and uses Silver Chariot to knock Kakyoin out with silver chariot. The group agrees to figure out what to do with Kakyoin in the morning and all decide to go to sleep. The Baby reveals that he had the scorpion inside his mouth the whole time and prepares to make his move.
