Symphony No. 9 (交響曲第9番 Kōkyō Kyoku Dai Kyū-ban?) is the fifty-nineth chapter of the Dandadan manga series.
Summary[]
With the conductor eliminated after Aira attacks him, the Music Room Portraits lose their ability to levitate and shifts the environment to a large chorus who surround Okarun and Aira. While fighting them off, Aira uses her Acrobatic Silky hair to lift the Turbo Granny in the air to find the Music Room Portraits hiding behind four giants and then has her hair wrap around one of the giants to swing herself on top of its head along with Okarun. Okarun and Aira then avoid an attack from two of the giants after they notice them, which ends up hitting the giant they were standing on. While still in the air, Aira kicks Okarun away to have him target the Music Room Portraits and is caught by one of the giants next strike. Despite taking damage, Aira remains conscious after remembering the incident between Momo and the Evil Eye and uses her Acrobatic Silky hair to blind the giants and have them attack each other as she moves around. As he dodges the explosive musical notes to get close to the Music Room Portraits, Okarun is instructed by the Turbo Granny to defeat them all with a single attack, as she states that her power would allow her to easily hit five notes in one beat, and attacks them simultaneously with a succession of headbutts per Musician.
