Satoru is the head doctor of TG University Hospital, and a member of the Rokakaka Organization. Supposedly 89 years old, he is an elusive figure with almost no public presence despite being in charge of a major institution of medicine.
Satoru 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 into it. He also wears dress shoes and uses a cane to walk.
Satoru is revealed to have a thin furrowed face with prominent cheekbones and sunken eyes. His most notable features are a beard styled into multiple short spikes and a monocle on his right eye. His hair is lightly colored and cut very short, appearing to be divided into small square patches. His sideburns feature the same square pattern, but are much smaller and are far apart.
Satoru's personality is currently a mystery. He's a rather elusive figure despite holding an incredibly prestigious title. Similarly to other Rock Humans he demonstrates antisocial behavior, completely ignoring Josuke Higashikata, Yasuho Hirose, and Rai Mamezuku. While he avoids direct confrontation with the trio, he's the user of a ruthless automatic Stand ability that attacks anyone attempting to chase after or find him.
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.
Unnamed StandSatoru is the user of a currently unnamed humanoid Stand. The head doctor's stand is mechanical in appearance, and possesses an automatic ability that functions at an extremely long range. The ability is activated by any person attempting to pursue Akefu. As estimated by Rai Mamezuku, once a person has been targeted by this Stand, any attempt to pursue its user will cause it to appear and re-activate its ability, regardless of the target's distance from the head doctor. In an extreme display of its sensitivity to pursuit, Satoru's ability was re-activated by the mere discussion of Josuke and Mamezuku attending a lecture by the head doctor with intent to confront him. Satoru's Stand attacks by causing nearby objects to collide with its victims with an amplified force that inflicts greater injury than would be possible under normal circumstances. The exact mechanisms of this attack are unknown. This is best demonstrated when a discarded cigarette imbued with the Stand's power strikes Josuke's hand with enough force to pierce his palm. A bystander was shown to suffer a sudden, fatal 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. Smaller objects seem to cause more extreme and immediate damage (i.e. rain drops striking with the force of bullets) while the impact caused by larger objects takes a bit of time to effect a target (as seen in the aforementioned car example).
As head doctor of TG University Hospital, Satoru seemingly oversees research on the Rokakaka fruits and gives orders to fellow Rock Human doctors, such as Wu Tomoki, Urban Guerrilla, and Poor Tom. Due to his honorary position, he is stated to not be involved in any actual medical practice.
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.
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.
