Sugar Mountain

Sugar Mountain (シュガー・マウンテン) is a minor, neutral character featured in Part VII: Steel Ball Run.

An old woman with the appearance of a girl, along with her parents and others, she is trapped by and made guardian to a large Tree possessed by the Stand, Sugar Mountain.

Appearance
Sugar Mountain is a pretty, petite teenage girl, with dark hair in a bob cut and straight, eyebrow-level bangs. She wears a bonnet, and a grape-shaped necklace; a short black dress, a white one underneath; cougar patterned sleeves, panties, and long-socks with a pair of leather boots.

Personality
Her real age 66, Sugar Mountain has made a home inside the Tree, in which she passes time role-playing with dolls, in the manner of a young child. Johnny deduces that she is sight impaired, noticing the mark of a cane around her abode. Otherwise, she is conscious of her history, her role as captive and guardian to the Tree, and the nature of its Stand.

Synopsis
She encounters Gyro and Johnny while they search for the Ears and Right Arm of the Corpse after she steals one of Gyro's Steel Balls. After a brief introduction, Gyro attempts to search for it in her Tree. She asks the pair a series of questions, offering in an exchange not only Gyro's Ball, but money, a piece of gold ore and a few gemstones.

A sort of game emerges to Gyro's understanding. When he severs the ears of the rabbit Johnny caught earlier and drops it into the spring by the Tree, Sugar Mountain produces the Ears of the Corpse, to her surprise. At some point before departing her, Gyro also drops the rabbit's (right) arm, retrieving the Corpse's Right Arm.

As per the rules of the Tree's Stand, Sugar Mountain; Johnny and Gyro are obligated to use or spend everything they gained in their exchange with her before sunset, under threat of the both of them joining the the Tree's collection of inanimate human "fruits".

When they succeed, along with her parents, Sugar Mountain is released from the Tree.

Trivia

 * In both appearance and her capacity as blind or severely sight impaired, Sugar Mountain bears a strong resemblance to Daiya Higashikata of JoJolion.
