The Rokakaka Smuggling Organization is a covert group whose goal is to secretly obtain and sell Rokakaka fruits. The group was lead by Tamaki Damo. Working under him were Yotsuyu Yagiyama, Aisho Dainenjiyama, and the A. Phex Brothers. Jobin Higashikata served as a buisness partner who used his family's business to launder money for Damo. The group's primary goals were monetary, wishing to market the Rokakaka fruit to sick or injured clients willing to pay a high price for an opportunity to recover. Spikes or bulbs similar to those found on the Rokakaka fruits themselves seem to be a recurring design element among those involved in the smuggling operation.
The organization secretly imports Rokakaka fruits from New Guinea with the help of Jobin, who transports the Rock Humans and the fruit in and out of Japan as shipments from and to the Higashikata Fruit Company. In Japan, the fruits are transported in various ways and between members of the organization, until they are sold to wealthy clients afflicted in normally untreatable ways. The Rokakaka's miraculous properties allows it to heal anything, thus it is highly sought after by whoever knows of its existence. It is sold at 200,000,000 yen for each fruit. During the transaction, the clients are required to be alone and pay in cash.
The organization seeks to preserve the secret of the Rokakaka to themselves, and thus restricts its customer base to a few wealthy people. In order to notice thefts, each tree is weighted at every step of a transaction. When someone discovers the Rokakaka, the Organization tracks down the culprit with the full intention of killing them.
After they robbed branches from the organization, Tamaki Damo went after Yoshikage Kira and Josefumi Kujo and almost killed both. However, extraordinary circumstances led to Kira and Kujo escaping, resulting in the birth of Josuke Higashikata. Josuke's inquiry about his past led to fights between him, Yasuho Hirose, Norisuke Higashikata IV and Tsurugi Higashikata against Yotsuyu, Aisho and the A.Phex Brothers. Damo was forced to confront the Higashikata family alone and was killed by Hato Higashikata and Josuke's concerted efforts.
Jobin eventually becomes the last remaining member of Damo's underground trade opperation. Although he clearly showed signs of distress over Damo's death, he has continued the former's hunt for the stolen branches for his own covert motivations. Rai Mamezuku later reveals that although he heard news of Damo's death, Damo himself isn't the only enemy. There are others that have slipped into society unnoticed and won't stop until they have the Rokakaka in their possession. As such, this new threat obtains info on Rai's existence and pursues him, leading to Josuke and Yasuho having to battle the Rock Humans Urban Guerrilla and Doremifasolati Do to protect Rai.
It is later implied by Urban Guerrilla that Damo's organization was separate from the group Rai theorizes about, however Urban Guerrilla and his associates chose to peacefully coexist with them, as the nature of Damo's buisness did not pose any form of serious threat from their perspective. However, members of this group seemingly look down upon Damo's behavior, viewing them as no better than common drug dealers.
