JoJo's Bizarre Adventure

Season 4: Diamond Is Unbreakable

Episode 26: Janken Boy Is Coming!

Yoshihiro decides to use the arrow to make more Stand-wielding allies, first using it on a boy named Ken Oyanagi. Ken then pesters Rohan to play Janken with him, losing his first match after Rohan uses Heaven's Door to figure out his move. As Ken continues to force Rohan to play Janken with him and manages to win his third match against him, his Stand, Boy II Man, appears and tries to suck in Heaven's Door. Rohan soon learns that Ken's Stand allows him to steal energy from others and keep it if he wins three times out of five, discovering that he has already gained a third of Heaven's Door's ability. Ken then wins the fourth match, gaining more of Heaven's Door's ability and evening the score. After holding on with a pair of ties, Rohan manages to win his third match and retrieve Heaven's Door after borrowing Shizuka the invisible baby from Joseph and having her change what Ken attempted to throw out. Ken attempts to kill himself by jumping in front of the truck, but Rohan manages to use his own brand of luck to save him, convincing Ken to stop using his Stand for evil.
