Sweetpea

Hanagaki Takemichi is a worthless part-time worker who's down in the dumps. One day, he gets pushed off the station platform onto the railroad tracks with a train coming right for him, but the next thing he knows, he's reliving his life from 12 years ago.

Takemichi returns to the present after shaking hands with Naoto and is reunited with Naoto who is now a police officer. Naoto asks Takemichi to go back in time and prevent the two leaders of the Tokyo Manji Gang from meeting so that they can save Hinata.

In order to protect his friend Yamamoto Takuya who's a bit frail, Takemichi challenges Kiyomasa to a fight. Despite being beaten to a pulp, Takemichi doesn't back down, which starts to make Kiyomasa panic.

Takemichi gets to enjoy some happy times with Hinata during their middle school days until he's suddenly sent back to the present. After seeing how Mikey was, he can't imagine that it was Mikey that turned the Tokyo Manji Gang into an evil organization.

Naoto finds out that 12 years ago, the Tokyo Manji Gang had split into the Mikey Faction and the Draken Faction and due to one of their disputes, Draken ends up dying. However, Takemichi refuses to believe that Mikey and Draken would ever fight.

Because Pah-chin's friend was brutally attacked by Moebius, the Tokyo Manji Gang decides to fight Moebius. According to Naoto, Draken doesn't die because of the conflict with Moebius, but rather, an internal conflict between the Tokyo Manji Gang.

Takemichi goes back to the past and tries to stop the upcoming conflict between the Tokyo Manji Gang and Moebius, but Mikey and Pah-chin refuse to change their minds. Meanwhile, Osanai barges in with members of Moebius to launch a surprise attack.

After the attack initiated by the head of Moebius, Mikey and Draken end up at odds with each other and then go visit Takemichi, who was injured. Takemichi is infuriated when the two of them end up fighting and destroying a bunch of his belongings.

After receiving some information from Naoto, Takemichi goes to the parking lot where Draken is supposed to die. He finds Draken taking on Moebius all on his own.

While the battle between Toman and Moebius led by their current leader, Hanma Shuji, is raging on, Draken ends up being stabbed by Kiyomasa. Mikey tries to get to Draken who is gravely injured, but Hanma keep getting in his way.

Takemichi manages to defeat Kiyomasa in their one-on-one by sheer tenacity and with the help of Akkun and the others, they're able to protect Draken until they can get him to the ambulance. However, Draken is still unconscious.

After saving Draken's life, Takemichi returns to the future to find that Akkun made his dreams to become a hairstylist come true and the accident caused by Toman that killed Hina never happened.

After Hinata's funeral, Takemichi tells a grieving Naoto what he plans to do next. Why did the same future happen even though Draken remained by Mikey's side?

The Tokyo Manji Gang welcomed a new captain for their Third Division and it happened to be the former member of Moebius, Kisaki. Some members raise their doubts, but Mikey explains that they need Kisaki's strength to face their new threat, Valhalla.

Mikey asks Takemichi to bring the former First Division Captain Baji Keisuke from Valhalla. Mikey agrees to make Kisaki leave Toman if Takemichi is successful in this mission, but he also threatens to kill him if he fails.

2 years ago, Mikey, Draken, Baji, Mitsuya, Pah-chin, and Kazutora had their gang uniforms made and they all took a trip to Kanagawa on their motorcycles.

Takemichi finds out about Baji and Kazutora's past and realizes how hard it's going to be to bring Baji back to Toman. The next day, Takemichi tries to figure out what to do about his promise to Mikey when Baji's second in command appears before him.

Back in present day, Draken tells Takemichi that Kazutora ends up killing Baji at the Bloody Halloween, the fight against Toman and Valhalla, and Mikey ends up killing Kazutora.

The Bloody Halloween conflict that results in Toman being taken over by Valhalla has finally begun. Hanma and his army of delinquents overwhelm Toman as Draken does his best to try to protect the other Toman members, putting him at a disadvantage.

During the Bloody Halloween, Mikey ended up in a 1v3 fight against Kagetora with his limbs bound. After Kazutora hits him in the head with a pipe, Mikey ends up on his knees. The Valhalla members see this as a chance to finish off the Invincible Mikey.

Baji had infiltrated Valhalla so that he could get to Kisaki. And after a fierce battle, he manages to get to Kisaki, but coughs up blood and falls to the ground. Mikey sees this and takes Hanma out in a second and starts mercilessly punching Kazutora.

Two years ago, Mikey learns that Kazutora is beefing with the Black Dragons, and decides he'd fight them as well. But he wanted a valid sense of purpose to take on a motorcycle gang. Baji then suggests they make their own motorcycle gang.

The conflict between Toman and Valhalla dubbed the Bloody Halloween ends in Toman's victory, but Baji is killed and Kazutora is arrested. Takemichi regrets that he wasn't able to do much, but they managed to avoid Mikey killing Kazutora.

Takemichi heads to his first Toman meeting wearing his jacket and is surprised to see the vice commander of Valhalla, Hanma, and Chifuyu standing next to Mikey. Not only that, but he finds out that it was Kisaki Tetta who arranged all of this.
