Summary
Josuke and Rohan have to play a last roll of cee-lo, with Rohan not knowing that his die are the shape-shifting alien Mikitaka, who works for Josuke and Tamami acting as an arbitrator. Rohan rolls first a 3-3-4, a normal roll, but with Josuke's relief being visible, Rohan guesses that Josuke has an accomplice. When Josuke takes the dice in his hand, he sees that Mikitaka is throwing up for having been thrown so many times and cannot roll yet. Rohan grows more suspicious and orders Josuke to show the dice.

Josuke slowly opens his palm, but a siren is suddenly heard. Blisters appear on the dice and Josuke cannot buy time anymore. Hoping that Mikitaka overcame his motion sickness, he rolls the dice, and gets another triple 6. Tamami confirms with The Lock that Josuke has cheated, and asks Rohan if he's discovered how Josuke cheats. With the firetruck approaching, the dice begin to distort itself, fortunately, in a way Rohan can't see from his side of the table. However, the situation is dire as Rohan prepares to pick up his dice and when Mikitaka finally gives in to his allergy to siren and motion sickness, the dice transform back.

Tamami distracts Rohan by pointing out the fire inside his house, saying that Rohan's magnifying glass must have started it. Both cannot see Mikitaka transforming, and Josuke manages to hide him against his body when Rohan turns his head, and proceeds to take the 2 million and heal Rohan's finger before fleeing. Josuke and Mikitaka get away scott free while Rohan's house has partially burned down, greatly increasing his grudge against Josuke.
