Hanagaki Takemichi is a worthless part-time worker who's down in the dumps. Takemichi is shocked by news that his ex-girlfriend was killed, but goes about his daily life when he is suddenly pushed onto the railroad tracks.

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.

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. Then, the commander and vice commander of the Tokyo Manji Gang, Sano Manjiro, AKA Mikey, and Ryuguji Ken, AKA Draken show up.

Takemichi gets to enjoy some happy times with Hinata back during their middle school days but then he is suddenly sent back to the present.

Takemichi renews his determination as he goes back in time yet again, but when he opens his eyes, he finds a girl he doesn't know wearing just her underwear looking down on him.

Because Pah-chin's friend was brutally attacked by Moebius, the Tokyo Manji Gang decides they're going 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 returns to the present to talk to Osanai, the leader of Moebius, to find out what really happened that day.

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. Pah-chin challenges Osanai to a one-on-one, but Osanai is two years older than him and beats him to a pulp. Despite this, Mikey doesn't interfere and just keeps watching it happen...

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 precious belongings. Akkun and the others try to stop him, but Takemichi ends up in tears, saying how much Toman means to him. His words get to Mikey and Draken and it seems like the mission was a success because of their reconciliation, but...

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. Takemichi and Mitsuya try to help Draken, but they are overwhelmed by the number of Moebius members. It was then the person behind the "Draken hunting" showed himself.

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. Mikey then asks Takemichi to take care of him instead. While they're waiting for an ambulance, Kiyomasa and his thugs get in their way. In order to protect Draken, Takemichi challenges Kiyomasa one on one to settle things with him once and for all.

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. Meanwhile, The fight between Toman and Moebius came to an end. As he leaves, Hanma warns Mikey of the creation of Valhalla and the fact that he's the vice commander of this new gang.

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 reuniting with Naoto, he finds out that Hina is alive, and they go to see her. Right before they're supposed to see her, Takemichi starts having some doubts because he's embarrassed at the fact that he hadn't changed at all and suddenly says he doesn't want to see her.

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? Takemichi decides he wants to go see Draken and ask him himself, but they find out that he's no longer in Toman in this world and is on death row.

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. But Takemichi knew that Kisaki is the reason that Toman slowly turned evil and Hina and Akkun lost their lives, so he just can't hold back, and...

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. As Takemichi receives a lecture about Valhalla from Yamagishi who is knowledgeable about delinquents, Valhalla's No. 3 Hanemiya Kazutora appears before them.

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. Meanwhile, their commander Mikey rode his moped, Street Hawk. They get surrounded by a local biker gang, but Mikey shows no fear and tells the older gang members that he'll kill them if they lay a finger on his Street Hawk.

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 was trying to figure out what to do about his promise to Mikey when Baji's second in command, Matsuno Chifuyu appears before him. Chifuyu seems to believe that Baji joined Valhalla not to crush Toman, but to infiltrate Valhalla and expose Kirisaki.

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. Because of that, Mikey falls into darkness, and Toman is taken over by Valhalla, which leads to the evil organization that it currently is now, led by Kisaki. Takemichi goes back to the past with a new mission: to protect Baji so that this tragedy doesn't happen.

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. However, the Toman members see how desperately Takemichi is trying to save Baji and Mikey, lighting their fighting spirits once more.

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 and try to get to him. Draken and Takemichi try to save Mikey, but they're too far away. But then, a rather surprising person came to Mikey's aid.

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 over and over. This was the scene that the future Draken had told Takemichi about. At this rate, Mikey will end up killing Kazutora, Kisaki will take over Toman, and the tragic future will still occur. Takemichi tries to stop him, but Mikey's rage is just too great, and...

Two years ago, Mikey learns that Kazutora is beefing with the motorcycle gang, 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. They want to create a gang where they can all put their lives down on the line for each other. Baji had been fighting all alone to protect the promise they made the day they created their gang and put their money together to buy a traffic safety charm.

The conflict between Toman and Valhalla dubbed the Bloody Halloween ends in Toman's victory, but Baji is killed and Kazutora is arrested. Takemichi is regretful about the fact that he wasn't able to do much, but they managed to avoid Mikey killing Kazutora. After going with Draken to visit Kazutora, they head over to Draken's home.

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. Takemichi falls into despair when he realizes he wasn't able to change the future again despite Baji sacrificing his own life to protect Toman. And then, Chifuyu says...

Back in the present, Takemichi is stunned to learn that he has become officer in Toman. Kisaki seizes an opportunity to dupe him, and Takemichi finds himself staring down the barrel of a gun.

Back in the past, Takemichi befriends Hakkai Shiba, and has a violent run-in with Black Dragon.

Takemichi is beaten to a pulp by Taiju Shiba. To save him, Hakkai proposes a bargain to Taiju.

Hakkai decides to join Black Dragon to save Takemichi, but Mitsuya opposes it and confronts Taiju.

Propelled by each their own motives, the alliance members head to the church on Christmas night.

Takemichi gets back in the fight to protect Yuzuha, who is key to changing the future.

After making a bold declaration, Takemichi keeps rising up from Taiju's beatdowns.

Takemichi returns to the past and realizes what he must do after meeting Chifuyu.

Set on crushing Toman, Yokohama gang Tenjiku ambushes Takemichi and his friends in Shibuya. The situation turns desperate for Takemichi when an old foe and one of Tenjiku’s Big Four show up.

At Tenjiku's hideout, Takemichi encounters a childhood friend who gives him disturbing information.

Back in the present, Takemichi and Naoto come under threat while gathering information.

Just when Takemichi's resolve is rekindled, a wrench is thrown into his plans.

While Tenjiku awaits the coming battle, Toman's members flinch at entering into a hopeless fight.

As the brawl begins, First Division tries to clear a path to Kisaki for Takemichi.

Hakkai and Angry must figure out how to overcome the formidable combination of the Haitani Brothers.

With a seesawing battle that may never end, Kisaki steps in, but Takemichi does not flinch.

Mikey and Draken show up at the pier and the battle between Mikey and Izana begins.

Out of desperation, Izana takes rash measures and the situation gets out of control.

With things coming to a close, Hanma and Kisaki escape with Takemichi and Draken in pursuit.

The war with Tenjiku reaches a deadly conclusion. Takemichi takes this chance to tell Mikey he is a Time Leaper, and explains everything he has been through. After hearing the truth, Mikey announces that the Tokyo Manji Gang is disbanding. The legendary organization that once stood at the top of Japan has come to an end.

Following Tokyo Manji Gang's disbandment, Takemichi is about to return to his original timeline, but a forgotten Valentine's gift for Hina leads to an unexpected proposal. After burying a time capsule with his comrades and promising to meet again in 12 years, Takemichi makes a Time Leap. He arrives in a world where all his friends are living happily, but Mikey is nowhere to be found.

Twelve years later, the criminal underworld is ruled by Bonten, an organization far more vicious than the old Tokyo Manji Gang. Takemichi is stunned to learn that Bonten is led by someone from his former life. He wants to go back in time, but the power he once relied on is now out of reach. With no way back, Takemichi meets his friends to open the time capsule they buried 12 years ago.

Takemichi plays the videotape Mikey slipped into the time capsule, which includes a message meant just for him. Mikey from twelve years ago reveals a darkness inside him that Shinichiro, Emma, and Baji had kept at bay. Having lost everyone who could stop him, Mikey has cut ties with Tokyo Manji Gang, distancing himself from his friends. After learning of Mikey's anguish, Takemichi ignores the danger and tries to make contact.

Takemichi desperately reaches out to grab Mikey as he leaps from the rooftop. Thrown ten years into the past, Takemichi lands in a world two years after Tokyo Manji Gang disbanded, where a war for supremacy rages between Rokuhara Tandai, Brahman, and Kanto Manji.

Takemichi lands in a brutal clash between Rokuhara Tandai and Brahman. Both gangs are desperate to recruit him, but Takemichi has his own agenda. He shocks everyone by declaring that he wants to take down Mikey, leader of Kanto Manji. After the police intervene and Rokuhara Tandai retreats, Takemichi comes face to face with Brahman's leader.

After Takemichi awakens a new power, he is haunted by a vision of death. He pushes the dark premonition aside to attend a Brahman meeting, where Senju announces her plan to ignite the War of the Three Titans. With war looming, Takemichi and Senju deepen their bond at an amusement park.
