Takemichi is the main character of Tokyo Revengers. At the beginning of the anime, he goes back in time after almost getting hit by a train. Realizing that he could stop the deaths of his loved ones by going into the past, Takemichi does anything that he can in order to save them by learning how his power works to prevent future tragedy.
However, Takemichi changes the timeline in many ways besides saving people, which he isn't even able to do as much as he hoped he would. From changing the careers that people have to the relationships that people have with each other, there are multiple ways that Takemichi changed the timeline from the anime.
10 Naoto Becomes A Police Officer
In the original timeline, Naoto dies the same day as Hinata. When Takemichi first goes back in time, he met a younger Naoto and warned him about what would happen. Wanting to save himself and his sister, Naoto decides to become a police officer. As a result, he's able to save Takemichi from being hit by the train that would have killed him but revealed that Hinata still died. Takemichi and Mikey work together afterward in order to make sure that they can save her and anyone else that the evil version of Toman in the future kills.
9 Akkun Never Stabs Kiyomasa
At the beginning of the series, Takemichi and his friends are forced to fight in Kiyomasa's fight club. Akkun planned to stab Kiyomasa, and did so in the original timeline, resulting in him going to prison. However, Takemichi challenged Kiyomasa to a fight, which caused him to become close friends with Mikey and Draken. Akkun became part of Toman's upper echelon as a result. He eventually becomes very scared of Toman's new leader, Kisaki. He follows all of his orders and attempts to kill Takemichi, as well as himself.
8 Mikey & Draken Become Friends Again After Pah's Arrest
After Pah is arrested, Mikey and Draken have completely different views on the situation. Mikey wants to save Pah while Draken wants to respect the decision that Pah made. In the first timeline, they never became friends again.
However, with Takemichi being their friend, they both went to his house at the same time and the two of them fight. Takemichi was able to get them to stop fighting and become friends again while also proving to be a great friend to both of them.
7 Draken's Life Is Saved
Draken originally dies on August 3rd. While Takemichi thought that he'd stopped Draken's death by ensuring he and Mikey were friends again, he discovers that Kiyomasa, Peh, and the members of Moebius are still a threat to Draken's life. Kiyomasa is even able to stab Draken. Takemichi desperately wants to save his friend and does everything he can to make sure he won't die. By fighting Kiyomasa and making sure that Draken safely gets to a hospital, Takemichi is able to save his life.
6 Kazutora Lives Beyond The Bloody Halloween
Kazutora is another founding member of Toman that Takemichi saves. Kazutora, Mikey, Draken, Baji, Mitsuya, and Pah were childhood friends that formed Toman together. However, after Kazutora kills Mikey's brother, he leaves the gang. Kazutora is originally supposed to be killed by Mikey in the Bloody Halloween after he murdered Baji. However, in the hopes that it would stop his old friends from fighting and killing each other, Baji takes his own life. Mikey ends up letting Kazutora go and forgives him.
5 Members Of Valhalla Join Toman
In the timeline where Mikey kills Kazutora, he falls into darkness, allowing Valhalla to take control of Toman. However, after Toman wins the Bloody Halloween and Kazutora lives, Kisaki and Hanma decide they'll have Valhalla join Toman. The members of Toman find out when Hanma goes to one of their meetings. While they're confused at first, they're thrilled to learn that Toman gained 300 more members. But they didn't know that, regardless of how the Bloody Halloween ended, they would have all played into Kisaki's hands anyway.
4 Takemichi Becomes The First Division Captain In Toman
Baji is the original captain of Toman's First Division. After he dies, Chifuyu is supposed to take over. However, because Takemichi goes back in time, he's able to become close friends with Chifuyu.
The two of them agree to help each other out and Chifuyu decides that Takemichi should take Baji's place as the First Division's captain, and Mikey agrees. Takemichi wants to become Toman's leader. By earning an important position in the gang, he's one step closer to reaching that goal.
3 Takemichi Never Has His Job At The DVD Store
When the series began, Takemichi feels like a loser, partially due to his hatred for his job. He works at a DVD store and is a bad employee. He even gets fired due to spending so much of his time in the past rather than going to work. However, because he becomes Toman's First Division captain, he never works at the DVD store. Although he visits the DVD store when he goes back into the future at the end of season one, he's a regular customer instead of an employee.
2 Takemichi Becomes A Toman Executive
Takemichi is very confused when he goes back to the future in the last episode of Season One, and not just because of how he's treated at the DVD store. His appearance had changed, he had his own limo and fancy home, and a lot of strangers respected him, doing whatever he wanted. While he's not sure what's going on at first, he soon learns that he became the top executive of Toman, with other members such as Kisaki, Pah, Yasuhiro, Nahoya by his side.
1 Chifuyu Betrays Toman In Order To Avenge Baji
During a Toman executive meeting, Hanma reveals that some of their locations have been raided by the police at the same time, meaning that they have a traitor among them. When Kisaki asks to speak with Takemichi and Chifuyu in private, he confronts them about being the traitor. While Takemichi has no idea what was going on, Chifuyu confesses that he betrayed Toman in order to avenge Baji, which he'd wanted to do for twelve years. Although he tells Kisaki that Takemichi has nothing to do with his betrayal, Kisaki shoots both of them.
