Rokakaka Smuggling Organization

The Rokakaka Smuggling Organization is the tentatively-named mysterious, secret smuggling operation formed of a select group of Rock Humans and humans. The group's members are the current main antagonists of JoJolion.

Description
The Rokakaka Smuggling Organization is a covert group whose goal is to illegally make a profit out of the trade of the Rokakaka fruits. One of its higher-ranking members was Tamaki Damo, and his only known subordinates and/or associates were Yotsuyu Yagiyama, Aisho Dainenjiyama, the A. Phex Brothers, and Jobin Higashikata. It is currently unknown who leads the organization, but they reside in society seemingly unnoticed and will stop at nothing until the Rokakaka fruit is theirs. 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 cell. 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 to unseen force to protect Rai.
