Enter Sex Pistols (5) (セックス・ピストルズ登場 その⑤ Sekkusu Pisutoruzu Tōjō Sono 5), originally A Bad Omen! (縁起悪ィぜ！ Engi Warii Ze!) in the WSJ release, is the four hundred sixty-sixth chapter of the JoJo's Bizarre Adventure manga. It is also the twenty-seventh chapter of Vento Aureo.
Mista begins worrying over having only four bullets left. He rides the truck on a different route heading back to the port. However, to the shock of Mista, Sale appears up the road. By using stones stopped in space, Sale was able to get ahead of the truck, and quickly approaches Mista. By continuously poking a stopped bullet, Sale is able to build up a large amount of energy into the bullet.
He releases the bullet, hitting Mista in the abdomen. In retaliation, Mista shoots three bullets, all missing. Sale, feeling confident, prepares to finish Mista, however this was all part of Mista's plan. The number four is an unlucky number. By wasting three, Mista now has only one bullet. With Lady Luck on his side, Mista assumes his victory.
