Villain Overview
The head doctor... has no face. I've met him countless times. That's the kind of person he is. That's the kind of ability he has.
~ Holy Joestar-Kira on Satoru Akefu.
Whomever it may be, they would be always better off without pursuing me...
~ Satoru Akefu

Satoru Akefu is the secondary antagonist in JoJo's Bizzare Adventure: JoJolion.

An extremely enigmatic doctor, Satoru is the head doctor at the TG University Hospital and secretly the mastermind behind the rock human Locacaca Organization, the most prominent antagonistic faction in the story, which uses the fruit for research and smuggling purposes, and wants control over the New Locacaca for it's own ends.

It is also revealed that Satoru himself is a Stand named Wonder of U that is powered by the "calamities" of those who witness him, and that his Stand User is Tooru.


In his first appearance, he tries to meet up with Poor Tom to get the Locacaca branch, disguising himself as an ambulance worker alongside Wu Tomoki. However, he is foiled by Jobin and Tsurugi Higashikata, who give them a pear branch instead. He is later chased after by Josuke and his allies, who he escapes by sending out his stand and hopping on a bus. He is then found at both Mitsuba Higashikata's son's school and nearby their house. Later on, Josuke and Rai Mamezuku decide to ambush the doctor as he's giving a lecture about the announcement of Locacaca 6251, which causes his Stand form to attack.

On the day of the harvest, Satoru is seen by Mitsuba, Yasuho, and Rai, somehow lurking around the Higashikata's house and the police station. In the house, his ability, through a chain of events, reveals the new Locacaca. After Norisuke dies, Satoru jumps into action, entering the house. As he passes through objects towards the heroes, Jobin is warned by Mitsuba of him hiding under the bed and attacks. The doctor, however, disappears, leaving a can of hair spray. The can later bursts, injuring Jobin enough to knock him out. Later on, Satoru heads to a bike station, assisting a reporter named Taoka with a interview. After said interviewer grows curious on Holly Kujo, the Locacaca, and possibly being in pursuit of him, Satoru kills him, decapitated by the Stand's abilities. He then heads after Josuke inside the labrotory, but knowing something might harm him if he does, he sends a Rock Insect known as Dododo De Dadada to attack Josuke and Rai, and revealing his identity as Wonder of U in the process.

After Dododo De Dadada is killed, Rai confronts Satoru. Surprised that Rai could get so close to him, Satoru taunts him about his parents' deaths, angering him. Rai grabs Akefu by the neck, and threatens to impale him. However, Rai misses, and he realises spherical chunks of his shoulder had been removed. It's revealed that it was Josuke's soap bubbles responsible for harming Rai, using a technique he hoped would kill Akefu. Rai collapses, but reveals the existence of the Spin to Josuke.


Satoru is a enigma personality wise, but what is known about him is that Saotru is elusive, calm, professional, and anti-social. He usually doesn't fight directly, but he does send out his Stand form to attack people. Satoru seems surprised when Rai is able to get within a centimetre of him. He is also very confident that he is invincible.

Powers and Abilities

The "flow", you see... is that you will get up from that chair, it is certain that you will stand up to pursue me. I am "Wonder of U", and the "flow" is always a calamity.
~ Satoru Akefu on himself.

As a Stand himself, Satoru's mainly attacks people trying to pursue it's master or the Stand itself. His main ability is to cause someone to undergo a large amount of unlucky experiences, with these experiences being called "calamities". This ability can range from causing things that could reasonably happen (Such as one cutting themself when making food) and cause things that are near impossible (Such as small, normally harmless things to forcibly collide with targets with great damage, or cause objects to suddenly explode). The size of the object also affects the general danger of it, with smaller objects being more effected and more deadly compared to larger ones. This ability, once previously activated, remains dormant on the attacker, and it reactivates when the afflicted tries to pursue or hurt Satoru. This ability can be mitigated by forcing Satoru to come to the attacker, rather than the other way around. He can also generate illusions of the head doctor that are able to phase through objects (Anyone who attacks one of these illusions is able to be attacked by the Stand itself or have the Stand ability activate), and use his human disguise to have one live a second life under it, with even non-Stand Users being able to see it.

Satoru himself is also a master at his medical craft.
