Bloody Halloween

The Bloody Halloween refers to the fight that happened between Toman and Valhalla that happened on 31st of October. This fight was spectated by many delinquents/delinquent gangs like Haitani Brothers, Leanman, and Hansen from the Ikebukuro Criminal Black Members who was overseer for the fight that day.

Summary
On the day of the battle, spectators gather at the abandoned car lot to watch the fight between Toman and Valhalla, as the victor of the fight will be one step closer to ruling Tokyo. Hansen, a member of the Ikebukuro Criminal Black Members, acts as an overseer for the fight and calls for both gangs to enter. Mikey thanks Hansen for overseeing the fight.

The representatives for Toman and Valhalla, Draken and Kazutora, respectively, step up to Hansen in order to determine the format of the battle: a five-on-five fight, or an all-out fight. Draken tells Kazutora to decide, as Valhalla started the conflict. Draken however states that they just have one condition: if Toman wins, they will take Baji back, however, Kazutora responds that Baji joined Valhalla on his own, so they cannot take Baji back now. Draken still insists on his goal, which angers Kazutora. Seeing Kazutora's temper, Hansen warns him not to start fighting yet. In response, Kazutora punches him telling Toman that Valhalla's goal is to torture them to death. Both gangs run towards each other, ready to fight and the fight begins.

As the fight between Toman and Valhalla begins, Takemichi searches for Baji, but gets caught in the brawl. Kazutora tries to punch Mikey, but is blocked by Draken, who tells him he is nowhere near Mikey's level. However, Draken is then preoccupied by Hanma, who kicks him, engaging him in a fight, which leaves Kazutora with Mikey, who tells Kazutora he will not hold back.

Momentarily distracted by seeing Kazutora with Mikey, Takemichi is beat up by a Valhalla member, but Mitsuya saves him, admonishing him for coming without being prepared to fight. Although Takemichi sees the necessity in fighting to achieve his mission, his lack of fighting skills lead him to become scared, especially when he sees two Valhalla members ready to fight him and begins to cry. Chifuyu appears behind him, reassuring Takemichi by offering to watch his back, and tells him to focus on the current objective. He says that though everyone gets scared during a fight, the important thing is how you handle it. Invigorated by both Chifuyu's words, as well as his drive to save Hina, Takemichi becomes eager to fight.

Takemitchi Hanagaki
After Takemichi helps resolves their dispute and prevents Draken's death, he returns to the present only to find out that Hinata and his friends still die in the current timeline. With only the clue that Tetta Kisaki transformed the Tokyo Manji Gang into a violent organization, Takemichi learns that the gang was absorbed into Valhalla and Mikey has become violent, having killed Kazutora over murdering Keisuke Baji on October 31, 2005. In the event called Bloody Halloween.

Baji Keisuke
The former 1st Division captain of Toman who recently changed sides to Valhalla a few days prior to the fight. But in the end, Baji was still fiercely loyal to Toman. He was willing to cast himself as the villain in his friends and comrades' eyes in order to protect them. In the end, he is even willing to sacrifice himself to ensure that Toman does not lose its way.

Aside from Takemichi(who is a time traveler in the series) Baji was the only one who suspected Kisaki to be the villain and enemy of Toman, Baji tells Takemichi that Kisaki is the enemy, something he realized when he witnessed Kisaki offering Mikey Pah-chin's freedom in exchange for the position as Third Division Captain

Even after being stabbed by his old friend Kazutora seeing that Mikey would've beaten him to death Baji stands up and stabs himself and nearing death he says the six founding members of Toman are his treasure, and although he was unable to fix Toman on his own and Mikey has no reason to kill Kazutora now, as Baji died by his own hands.

Even on his deathbed he warns Takemitchi about how Kisaki was the enemy and says that he is leaving Mikey and Toman in Takemichi's hands, to which Takemichi cries, telling Baji not to die. Baji lies in Chifuyu's arms, telling him that he would like to eat Peyoung Yakisoba somewhat comforting him in this grimsome situation. As he cries, Chifuyu tells Baji he will buy some, and Baji tells him they will split it like old times, thanking him with a smile as he dies. Chifuyu screams in agony.

Result
Toman wins the battle. Baji Keisuke dies.
