Sky High (2) (スカイ・ハイ その② Sukai Hai Sono 2), originally A 'Fast' Foe (「速い」敵 'Hayai' Teki) in the WSJ release, is the seven hundred seventh chapter of the JoJo's Bizarre Adventure manga. It is also the one hundred thirteenth chapter of Stone Ocean.
Jolyne, Emporio and Ermes find themselves unable to open their eyes without knowing why. Jolyne manages to force her eyelids open, and sees that the helicopter is crashing while Emporio is unable to find the autopilot button. Ermes yells that something is inside the helicopter with them, but it manages to avoid Jolyne's string net, making its presence unconfirmed.
Ermes sees that her hand is inflated and cannot understand the nature of the enemy. However, Jolyne decides to use extreme ways and makes everyone jump out of the helicopter. The falling speed allows Ermes to spot a skyfish Kiss crushes, but many skyfishes follow. Having attached herself to the helicopter, Jolyne manages to soften their fall and all crash into the water, unharmed and well again.
They are almost immediately confronted by Rikiel.
