Toru

"Yasuho-chan, [...] it looks like we ran into each other at a good time... Seems that's always the way with us..."

- Tooru to Yasuho Hirose, JJL Chapter 84

Tooru is the main antagonist of JoJolion. He is Yasuho Hirose's ex-boyfriend from high school and a part-time worker at TG University Hospital.

He is eventually revealed to be a Rock Human and a Stand user, wielding the calamity-causing The Hand.

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 is a meticulous and somewhat manipulative individual, proving himself as a person to be strategic. Like most villains in the series, he puts his goals above everything and everyone else. Therefore when he uses or sides with a person he uses them as pawns of his own interest with little to no regard for them unless it affects him or what he desires. For example, Tooru used Yasuho (her stand) when she was little by giving Tooru somebody for Wonder of U to impersonate. He claims that he loves Yasuho and that he wants to be in touch with her again. But it is later revealed that he was trying to use Yasuho and her stand again to contribute more to his scheme. For when Yasuho was dying at the estate, he shown almost no concern for her. Another example of manipulating a character might be how he shot Poor Tom likely because he didn't want his plans to be foiled.

He also seems to be a bit carefree and collective, most likely because of the ability of his stand. While his stand was getting attacked and he was about to get spotted by Jobin, he listens to some music instead of losing his composure. When he knows that Josuke has an ability that can possibly bypass the calamity and prove a threat, he tries to retreat and take the fruit instead of risking the fight. Which, during the retreat, he politely asks Yasuho for the New Rokakaka instead of trying to fight her and/or simply taking it away.

Early Life
Tooru was abandoned by his mother as a newborn, and left to survive in the wilderness. He continued his physical development inside a wasp's nest. Around 17 years later, he grew into his adult body, and killed the entire wasp's nest in the process. He then became a citizen of Morioh, and entered society undetected.

At some point during Yasuho's childhood, he appeared to her and tricked her into helping him find an elderly doctor for Wonder of U to impersonate. Yasuho, possibly with the help of Paisley Park, identified Satoru Afeku. Yasuho did not realize this was Tooru until much later.

During his high school years, Tooru dated Yasuho and the two seem to have been very close. One year before the events of JoJolion, he broke up with her. The reason Tooru decided to enter high school is unknown. He then became a part-time worker at TG University Hospital at an undisclosed date.

The University Hospital
He teases Yasuho and hints that their previous relationship was somewhat sexual, 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 path 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. Ultimately, he calls Yasuho and leaves a message declaring his love for her and saying he wants to get together with her again. When Josuke gets into trouble as a patient with a broken neck dies near Josuke, making it look like Josuke was the culprit, Tooru comes to the forefront again. Reassuring Yasuho as he promises to testify in favor of Josuke, Tooru gets again closer to her.
