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.

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.

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...

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 meets Hakkai and Yuzuha Shiba and forms a friendly bond. On the way to the Shiba's home, a chance meeting with Black Dragon turns violent.

Takemichi is beaten to a pulp by Taiju Shiba. In order to save Takemichi, Hakkai proposes a bargain to Taiju.

Disaster is avoided when Hakkai offers to join Black Dragon. However, Mitsuya will not allow Hakkai to leave Toman, and confronts Taiju.

Kisaki and Hanma offer their help to Takemichi and Chifuyu in the rescue of Hakkai and destroying Black Dragon. Takemichi and Chifuyu come to a decision.

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

Yuzuha's surprise attack on Taiju misses its mark. Takemichi realizes Yuzuha is the key to changing the future, so he gets back into the fight.

Mitsuya arrives at the church, but is seriously injured in a surprise attack. Finding himself in another pinch, Takemichi gathers himself and makes a bold declaration regarding the future of Black Dragon. Though Taiju continues to beat him down, Takemichi keeps getting back up to face him again.

After revealing his secret, Hakkai overcomes his fear of his brother and faces down Taiju with Takemichi. Just when defeat looks imminent, the familiar sound of a bike engine heralds Mikey's arrival at the church. However, something seems odd about him.

After defeating Black Dragon, Takemichi finds himself being taken by Mikey to Hina's place, to face the girl he broke up with just the day before.

After declaring victory over Black Dragon at Tokyo Manji Gang's first meeting of the year, Mikey makes an unexpected announcement.

Certain that he has changed the future, Takemichi returns to the present. However, the timeline he returns to is the worst one yet.

Takemichi returns to the past to change the horrific new timeline. After meeting Chifuyu, Takemichi realizes what he must do.

Back in the present, Takemichi and Naoto meet up with Taiju Shiba and learn who is essentially leading Toman. Then Inupi and Koko suddenly barge in there. Takemichi and Naoto try to make their escape but end up jumping from the frying pan into the fire.
