Vento Aureo - Chapter 21 
Moody Blues Strikes Back, Part 1 (ムーディー・ブルースの逆襲 その① Mūdī Burūsu no Gyakushū Sono 1), originally One More Mystery! (もう1つの謎！ Mō Hitotsu no Nazo!) in the WSJ release, is the twenty-first chapter of Vento Aureo and the four hundred sixtieth chapter of the JoJo's Bizarre Adventure manga.
Moody Blues' replay shows Narancia being deflated like a balloon and pulled into the yacht through a small hole. As a result, Bucciarati and Abbacchio conclude the enemy's Stand ability is to deflate both its opponents and themself and hide in small places such as pipes. Using Moody Blues' playback, Abbacchio begins tracking the enemy. When the enemy seems to get near, Bucciarati opens zippers in the floor, but is unable to uncover the enemy.
Despite its ability being known, it seems the enemy still has another secret keeping him from being discovered. Moody Blues cancels the playback, but gets trapped in a pipe. The enemy attacks Moody Blues and successfully wounds Abbacchio, who now understands the enemy's secret.
