Sugar Mountain (シュガー・マウンテン Shugā Maunten) is the title of a tertiary character featured in the seventh part of the JoJo's Bizarre Adventure series, Steel Ball Run, introduced in the "The Land of Promises: Sugar Mountain" story arc. An old woman with the appearance of a young girl, she is trapped by and made the current guardian to a Large Tree possessing a Stand of the same name.
Sugar Mountain is a pretty, petite girl, with dark hair in a bob cut and straight, eyebrow-level bangs. She wears a bonnet, and a grape-shaped necklace; a short dark dress, a light one underneath; cougar-patterned sleeves, and long socks with a pair of leather boots.
Her real age roughly 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. She holds Johnny and Gyro in high regard for their ability to escape the Tree's ability.
At one point in the past, Sugar Mountain and her parents encountered the great tree. Her father had dropped an axe and managed to acquire it back from the guardian, plus a golden axe for being honest. However, Sugar Mountain's family failed in using it up before sunset and their were turned into tree fruits, slumbering for so many years Sugar Mountain lost count of the time. It is estimated that she was prisoner of the tree for about 50 years. At one point, it is Sugar Mountain's turn to be the guardian of the tree.
She encounters Gyro and Johnny while they search for the ears and right Arm of the Saint's 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, Sugar Mountain, along with her parents, is released from the Tree.
- “My name is Sugar Mountain. This doll is called Candy. It’s nice to meet you… please make yourself at home.”
- “Those that are willing to lose… they’re the ones that ultimately gain everything. That’s the one thing I’ve come to understand since I’ve been guarding this spring. That’s the truth… and those two have earned that right.”
- Throughout the ages, each watcher over the Stand of the large tree is named Sugar Mountain, making it more of a title than an actual name.
