I'm an Alien (Episode)

I Am an Alien (ぼくは宇宙人) is the one hundred first episode of the JoJo's Bizarre Adventure anime and the twenty-seventh episode of Diamond Is Unbreakable. It covers Chapter 377 through Chapter 381 of the manga.

Summary
In search for other Stand users, Yoshihiro Kira is guided toward a strange-looking teenager. When the Arrow touches the man, it bounces back down the high herb, leaving only a scratch, to Yoshihiro's stupor.

Summer has arrived, and many tourists are coming to town as Jotaro Kujo and the Speedwagon Foundation's investigations are fruitless. One night, Yoshikage Kira practices Kosaku Kawajiri's writing while struggling against his murderous impulses, with his nails growing at an unnatural pace. When Shinobu enters to give him some tea, Kira almost strangles Shinobu, but she recoils in surprise at his touch. Shinobu mistakes it as a gesture for sexual advances. Unbeknownst to the two, a camera is hidden at a top corner of the room.

The next day, Josuke Higashikata and Okuyasu Nijimura spot a series of crop circles in the middle of which is laying the strange man from earlier. The man wakes up, and presents himself as an alien coming to Earth. Josuke and Okuyasu first take his claim as a joke, but cannot understand how that self-proclaimed alien swallowed a box of tissue, mistaking it for food. As the "alien" follows them, eventually proposing chilled ice-cream cones from his bag, the duo begin to think of him as delusional and try to debunk his claim. When some firetrucks pass near them, the siren causes the man, Nu Mikitakaze Nshi, to panic and transform into sneakers, and propel Josuke away from it. Now on the roof of his high school, Josuke tries to punch Mikitakaze with Crazy Diamond, but the alien doesn't even see it, convincing Josuke that Nu is an alien and not a Stand user. Nu is grateful, and wants to reward Josuke for "saving" him from the siren. Josuke, who laments that his mother froze his bank account after finding out about his lottery winnings, asks Nu to transform into a die, managing with difficulty to explain him its looks and its use.

Later, Josuke heads to Rohan Kishibe's house, begging the manga artist to play a game of dice in order to make money. Rohan accepts because he wants to take all of Josuke's money, but insists on using his own dice. Unbeknownst to Rohan, Josuke planted Nu in Rohan's house already. Setting the rules of a game of cee-lo, Josuke rolls first and obtains a triple six, winning the triple of his wager and thus six thousand yen. Rohan plays and obtains a 1-2-3, and loses the double of his ten thousand yen wager. As Nu has no sense of subtlety, Rohan is now suspicious that Josuke is somehow cheating.

 * Removed Rohan talking about the history of Cee-lo, and taunting Josuke about what the yakuza does to cheaters (shove two dice into your eyes and dump your body in the river; before they kill you, they stab you 21 times because 21 is what you get when you add up each side of the die).

Trivia

 * Although Rohan talking about the history of Cee-Lo was cut from the episode, it was in the episode's trailer.
