Satoru Akefu (Wonder Of U disguised form)

Satoru Akefu (明負 悟) is an antagonist featured in JoJolion.

Satoru is the head doctor of TG University Hospital, and mastermind of the Rokakaka Organization. He is also one of the organization's four researchers. Supposedly 89 years old, he's an illusive figure with no public presence despite being in charge of a major institution of medicine.

Appearance
Satoru's face has yet to be fully revealed. However, he is an elderly-looking man with a slightly stocky build. His arms and legs are noticeably slimmer than the rest of his body. He wears a dark-colored hat and suit, along with a lightly colored scarf with a pattern of irregular "-" shaped slits cut in it. He also wears dress shoes and uses a cane to walk.

Personality
Satoru's personality is currently a mystery. He's a rather illusive figure despite holding an incredibly prestigious title. Similarly to other Rock Humans he demonstrates antisocial behavior, completely ignoring, Yasuho, and Rai Mamezuku. While he avoids direct confrontation with the trio, he ruthlessly uses his Stand ability to stop them from pursuing him.

Abilities
Satoru is shown to be unexpectedly nimble and fast for a man that uses a cane to walk and is also approaching his 90s, a fact which caused Rai to question the doctor's alleged age on multiple instances. Satoru is the user of a currently unnamed humanoid. The head doctor's stand is mechanical in appearance, and seems to be capable of functioning at a fairly long range and attacking enemies without engaging them directly. While this stand's ability has not been elaborated on or defined, it would seem that it attacks by causing nearby objects to collide with its victims with an amplified force that causes greater injury than would be possible under normal circumstances. This is best demonstrated when a discarded cigarette imbued with the Stand's power strikes Josuke's hand with enough force to impale him.

It seems as though this Stand functions by transferring a force from an object to a person, and that the force this Stand embeds in people is transferable. A bystander was shown to suffer a sudden injury after coming into contact with Josuke's blood within moments of the latter being hit by a car that was presumably affected by the head doctor's ability.

Background
As the leader of the Rokakaka organization, Satoru oversees the research on the Rokakaka fruits and gives orders to his fellow Rock Human doctors, such as Wu Tomoki, Urban Guerrilla, and Poor Tom.

Ozon Baby's Pressure
Satoru along with his colleague Wu Tomoki attempt to meet with Poor Tom to retrieve the grafted Rokakaka branch. They disguise as ambulance drivers and arrive at the Higashikata orchard. However, they are tricked by Jobin and Tsurugi Higashikata into getting an ordinary pear branch from Poor Tom instead. They realize it was someone else other than Josuke and Poor Tom who lit the orchard on fire and that the other party now has the real Rokakaka branch.

The Wonder of You (The Miracle of Your Love)
Satoru is pursued by Josuke Higashikata, Yasuho Hirose, and Rai Mamezuku. Completely ignoring them, Satoru sends his Stand after the three and makes his getaway on a bus. He's later spotted by Mitsuba Higashikata at both her son's elementary school and on the property surrounding the Higashikata House.

Trivia

 * The revised chapter titles of Satoru's introduction arc in JJL Volume 21 implies that his Stand is likely named The Wonder of You (The Miracle of Your Love).
