I Am an Alien, Part 5 (ぼくは宇宙人 その⑤ Boku wa Uchūjin Sono 5?), originally I'll Take Your Pinky Finger! (小指をもらう！ Koyubi o Morau!) in the WSJ release, is the three hundred eighty-second chapter of the JoJo's Bizarre Adventure manga. It is also the one hundred seventeenth chapter of Diamond Is Unbreakable.
With Nu mimicking the dice in Rohan and Josuke's game of cee-lo, but having no idea how unreasonable his rolls are, Josuke's plan to rip off Rohan begin to fall apart as Rohan grows more suspicious. Rohan orders Josuke to get away from the dice and takes them to his house, soon coming back with a magnifying glass and the dice.
Rohan examines the dices, then tries to bite them to test their hardness, prompting Josuke to claim to have forgotten to wash his hands after going to the toiler to ward the mangaka off. The dice begin to sweat, making Josuke sneeze on them as a diversion. Bankrupted, Rohan takes another 60,000 yen and rolls a normal result of 2-3-5, but Josuke rolls another triple 6. Rohan is initially surprisingly calm, and jokes with Josuke before violently cutting off one of his fingers with a pen. Josuke is shocked, but Rohan forbids him from healing the finger, and declares it as punishment for not figuring out how Josuke cheats.
Rohan ominously wages 2,000,000 yen, saying that they will play one more time. If Rohan cannot discover how Josuke cheats, Josuke fixes his finger and gets the 2 millions as fee, but if he does, Josuke's finger gets cut off. Josuke refuses, but Tamami Kobayashi barges in, having been called by Rohan to put The Lock on Josuke to ensure he honors his promise. Cornered, Josuke has no choice but to play and win.
