After being freed from DIO's influence, he decides to join Jotaro on his quest to Egypt to save Jotaro's mother and find redemption.

Later, Kakyoin acquires two thin scars vertically crossing both eyes; which he often hides with a pair of dark sunglasses.

He is also referred to as beautiful upon arriving in India by a man trying to sell him a tattoo.

One of Jotaro's own admirers commented on his looks and during the Tower of Gray encounter, he swooned two female stewardesses.

As such, Kakyoin can control how Hierophant Green unravels, creating strong ropes or unraveling them into invisible strings. A single string has the ability to sense when someone is touching it and can attack either automatically or at Kakyoin's command. When a string is broken, Kakyoin is unharmed, but attacking a sufficient number of them or Hierophant Green's main body will harm him.

As Hierophant Green's original appearance is not humanoid, but instead just a group of connected membranes, it is able to unravel itself into multiple long strings for multiple purposes such as acting like ropes, avoid damage without hurting Kakyoin himself (as shown in the battle against Death Thirteen) or weave out a network of sensitive strings that detects the enemy's movements, as during the battle with DIO.

However, Hierophant Green's otherwise straightforward Emerald Splash does not lend itself to imaginative use of it.

Although it is mostly seen as a humanoid, Kakyoin states that its true form is that of a bunch of strings; as such one of his key tactics is to secretly unravel Hierophant Green's tentacles while keeping the main body as a distraction. Thanks to that, Kakyoin can infiltrate bodies, suddenly avoid attacks by unraveling his Stand, use the strings as ropes, and even perform piercing attacks.

Mastery Kakyoin is, due to a lifetime of possessing Hierophant Green, quite proficient at using it.

Kakyoin's long-range humanoid Stand is Hierophant Green; able to extend tentacle-like limbs or unravel to a modest extent; as well as fire a barrage of hard projectiles (an "Emerald Splash"). He is often seen shouting his signature attack (like the Emerald Splash) in fights.
