Toru

Tooru (透龍 Tōru) is the main antagonist in the eighth part of JoJo's Bizarre Adventure, JoJolion.

He is Yasuho Hirose's ex-boyfriend from high school and a part-time worker at TG University Hospital.

He is a Rock Human and a Stand user, wielding the long range Stand, Wonder of U.

Background
Tooru, like other Rock Humans, was abandoned by his mother as a newborn and left in the wilderness. He shortly after infiltrated a wasp nest to continue his physical development. Approximately 17 years later, he rapidly matured into his adult body, killing the wasp colony in the process. He then traveled to Morioh and entered society undetected. It is implied that he had a hand in killing Rai Mamezuku's father as Wonder of U's human form was briefly seen at Mamezuku's Father's funeral.

Roughly ten years before the events of JoJolion, Tooru meets a young Yasuho Hirose, then a little girl. Noticing how she used her Stand Paisley Park to search through her mother's phone, Tooru impresses her by scraping two rocks together to make a fire while assuaging her doubts about him. Tooru asks for a favor and tells her to help him find someone, stating that he doesn't know their name but that he knows they are an elderly with a medical license and that they live alone and are isolated from their family. Yasuho finds him a suitable person for his Stand to impersonate, Satoru Akefu. Tooru gives Yasuho the rocks to impress the other children at Yasuho's summer camp and disappears into the trees, wishing to meet Yasuho again after she'll have forgotten about him.

It can be inferred that he began impersonating Satoru Akefu with his Stand Wonder of U after that.

Tooru and Yasuho were revealed to have dated in High School, although it is unknown why Tooru decided to attend the institution. Apparently, Yasuho never looked up his last name. He then became a part-time worker at TG University Hospital at an undisclosed date.

JoJolion (2011)
Tooru encounters Yasuho during her confrontation with Wu Tomoki at TG University Hospital. He teases Yasuho about their previous relationship, but otherwise, the two are on good terms, as he is shown following through his promise to relay her message through to Josuke.

Afterward, Tooru repeatedly crosses paths with her as Yasuho follows Josuke and Rai across the hospital. Each time, he flirts with Yasuho and tries to remind her of their time together. He ultimately calls Yasuho and leaves a message declaring his love for her and says he wants to get together again. When Josuke gets into trouble after being accused of murdering a patient who died near him, Tooru reassures Yasuho as he promises to testify in favor of Josuke.

Tooru later meets Yasuho by the doorsteps of her house. After a speech about Tooru's aspirations and relationship regrets, Tooru asks her again to get back together but Yasuho is distracted by her investigation. Tooru offers his help and shows Yasuho a photograph of Satoru Akefu. Having seen the doctor's face, as well as confirming a link between him and Mitsuba, Yasuho decides to go to the Higashikata House.

Tooru doesn't accompany Yasuho but instead eats fast food for lunch. Yasuho calls him and asks him for help since she's injured at the Higashikata estate. Tooru says that he'll call an ambulance but Yasuho refuses, saying that she has a way to heal herself. Interested, Tooru departs for the Higashikata estate. Once there, Tooru ignores Yasuho's suffering and simply observes the estate from the surrounding forest while listening to music. When Satoru realizes Josuke's plan of "inviting" the head doctor to come to him, Tooru shows great intrigue at the sudden development.

Joshu comes out of the house with the Locacaca plant in his hands and Tooru retreats into the forest to remain unseen. Observing Joshu and Yasuho, Tooru decides to let Yasuho eat the fruit to confirm its power. Plus, he doesn't feel threatened by her. While hiding, Tooru makes some noise, and unwittingly allows Yasuho to realize that he's her enemy.

Yasuho confidently claims that he is the user of the calamity-causing Stand and a rock human. She dwells on their strange past together such as their first meeting when a young Yasuho was out with her troop. Tooru tells Yasuho that he appreciates her and has fond memories with her, warning her about the danger of her seeing him, since it would activate a calamity, killing her instantly. He then goes on explaining how the Higashikatas are already under this affect, as well as Rai and Josuke who he claims will die soon as well. Yasuho takes Joshu's phone and begins scrolling through the contacts. Tooru again warns her, asking for outsider assistance would count as a pursuit and lead her to be the first to die. Yasuho continues with her action and Tooru states that Yasuho has changed the order of death, meaning that she will die through calamity soon.

Tooru tells Yasuho that she is going to die next, but Yasuho doesn't listen to him and continues to talk with Kei Nijimura in order to find Josuke. Moments later, Tooru receives a wound to the head thanks to the combination of Soft & Wet's bubbles and Born This Way's wind power. Tooru realizes that there is indeed a hidden power in Soft & Wet's bubbles.

Appearance
Tooru appears to be a slim man on the shorter side, being just slightly taller than Yasuho. He has curly hair styled in an afro on his head, with two white swirls on either side. He has thick eyebrows which he constantly throws up to show cluelessness or general happiness (usually around Yasuho).

He wears a dark vest over a sweatshirt that ends halfway down his torso, leaving his lower abdomen exposed. On the right breast of the vest, there's a symbol for the letter "S" with a sun surrounding it. A similar yet smaller "S" can be located on the crotch area of his pants. On either shoulder of his sweatshirt are two teddy bears. His pants have a floral pattern on them, showing what appear to be grape vines and leaves.

Personality
Tooru appears as an amiable teen who longs to rekindle his relationship with Yasuho. Having already been her boyfriend, Tooru is not only friendly but also flirty with her. For instance, he doesn't hesitate to touch her in an intimate manner and isn't disturbed that Yasuho openly rejects his advances, being sure that she has feelings for him. He occasionally teases her too, openly reminding her of their experiences together. His love for Yasuho then pushes him to openly tell her he wants to get back together.

Otherwise, Tooru is cordial to those around him, even to Josuke who is suspicious about him. He also acts on his own initiative to save a child from choking, alluding to a heroic side.

However, Tooru seems also linked to Satoru Akefu's consciousness and is aware of what Akefu knows, showing that they have a unique relationship. Tooru's benevolence is thrown into question when he reappears at the Higashikata Estate and lets Yasuho die on the ground, instead listening to music and waiting to take the Locacaca.

Wonder of U
Although its powers have not been fully explained, it appears to be an automatic Stand that manipulates luck and karma in disfavor of anyone who thinks about pursuing, watching, or even hindering Akefu. The pursuer will get targeted by improbable disasters, to the point even normally harmless objects such as cigarette butts and raindrops can cause wounds as severe as bullet holes or improbable strings of events cause a worst case scenario. The ability's trigger is sensitive, as Mitsuba simply questioning the presence of Akefu was enough to activate it. The range of the ability is unknown, but it appears to be extremely large, as Josuke and Mamezuku were affected despite being nowhere near Akefu's whereabouts. In JJL Chapter 94, Mitsuba describes that the Stand's ability causes unforeseen bad things to happen again and again when someone see Akefu's back, making them feel like misfortune is chasing them down.

Rai Mamezuku theorizes that the head doctor everyone keeps seeing from the back is actually the Stand itself, and that the user is hiding. Moreover, he theorizes that the Stand is made of "calamity energy", whose power is directly related to the actions of the victim. For instance, Mamezuku's cellmate tried to stab Rai with a knife, but instead stabs himself because of the karmic retribution cast by the Stand.

Finally, the Stand seems to be able to cast illusions of its user. These illusions can appear on transparent surfaces such as windows, similar to Hanged Man's ability.
