Stardust Crusaders - Chapter 120 
D'Arby the Player, Part 7 (ダービー・ザ・プレイヤー その⑦ Dābī za Pureiyā Sono 7), originally I Know the Rules (ルールは知っている Rūru wa Shitteiru) in the WSJ release, is the one hundred twentieth chapter of Stardust Crusaders and the two hundred thirty-third chapter of the JoJo's Bizarre Adventure manga.
Atum steals Kakyoin's soul and inserts it into a doll. Telence compliments Kakyoin's ability to overcome his fear, and that he will have a special place within Telence's collection. Now that he has Kakyoin, Atum lets go of Jotaro's arm. Jotaro sits down, explaining that Joseph wouldn't stand a chance in a battle of video games. Jotaro picks "Oh! That's a Baseball!!" as their next game. It plays just like real baseball. The two pick their teams, and players. Jotaro's up to bat first, but swings way too early and gets a strike. After the pitch, Jotaro continues swinging. Joseph realizes that Jotaro has never played a video game before and is testing out the controls.
