Kate (ケイト, Keito) is someone who seemingly purchased drugs from Jodio Joestar in the past. It is unknown whether she actually exists, but the Undercover DEA Agent claims that she is a friend of Kate's in order to get Jodio to sell drugs to her. However, Jodio denies knowing who Kate is.
Bakin (BAKIN) is Rohan Kishibe's pet dog. Jodio Joestar believes that Rohan must have entrusted his pet dog to someone else in Japan while he is traveling. Rohan keeps photos of Bakin in his iPad, and Jodio remarks that it looks cute.
Leo (レオ, Reo) is a man with a distinctive haircut who buys an $80,000 watch from Diamotch for his girlfriend. He puts sunscreen on her back after she asks him to. He looks around upon seeing a flock of birds fly near them. They return back to their car and he complains to his girlfriend for sticking her fingers in weird places on his body while putting sunscreen on. Leo is unable to drive as Jodio and his friends are standing in front of his car, so he complains to them to move. Paco grabs his throat to check if his skin feels like sand like their enemy, but can't tell because of the sunscreen and his beard. Instead, Paco asks him and his girlfriend to show their ankles so he could see if they're injured.
Jodio opens the door on the passenger side and finds their assailant fused with the door, who is about to stab Leo's girlfriend. Jodio stops him by kicking her away, but the assailant shatters the door's window with his knife and escapes. Leo berates Jodio for assaulting his girlfriend and breaking his car's window, but Paco tells him to stop complaining or he'll give Leo a real injury. Suddenly, his girlfriend's watch falls off her wrist and bounces off Leo's foot, sliding toward the beach. Leo tries looking for the watch in the water while his girlfriend insults him and complains that he lost it. She decides to leave him, announcing she'll get a ride with someone else instead.
Mauka (マウカ) is the younger brother of Charmingman. He is under eighteen years old and lives with his elder brother on a farm. The two of them have a brotherly argument one day on the outskirts of their farm, which someone ends up reporting to the police. The next day, they race each other on their bicycles on a valley at Hualalai. Charmingman taunts Mauka for being too slow, causing Mauka to wonder if he was planning on doing an ironman triathlon. As Charmingman mentions that they'll be racing each other in a 2-mile swim as well once they get to the beach, there is a fallen tree in their path. Charmingman evades it, but Mauka suddenly falls off his bike and slides into a lava tube.
