Mystery of Soft Machine (2) (ソフト・マシーンの謎 その② Sofuto Mashīn no Nazo Sono 2), originally 5 Minutes Ago! (5分前！ Go Bun Mae!) in the WSJ release, is the four hundred fifty-ninth chapter of the JoJo's Bizarre Adventure manga. It is also the twentieth chapter of Vento Aureo.
As Giorno is stabbed and pulled into the boat by the enemy Stand, the fly made from Narancia's shoe continues flying around in search of its owner. Bucciarati uses Sticky Fingers to open a zipper in the floor where the fly was heading, but they were not below deck. Heading to the other side of the ship, Abbacchio reveals his Stand, Moody Blues, and uses its replay abilities to examine what happened to Narancia. The replay shows that Narancia received a circular wound in the back, dragged to the ground, and deflated.
