Takuya Yamamoto/Synopsis

Toman Arc
Takuya and his friends leave the train and decide to eat hamburgers. While sitting in the restaurant, Atsushi comments that he is surprised that Takemichi's cousin is the leader of Shibuya Third Middle School. Kazushi comments that if third years appear, they will drop Masaru's name, so no one would mess with them. Takemichi wonders what they mean, which surprises everyone, and Makoto reminds him they are going to fight the second years and hype themselves even more.

They reach the school, but are unable to find any second years. Takuya wonders if they are avoiding them and Kazushi guesses they heard they were coming and ran away. A moment later, third years led by Masataka Kiyomizu appear, stating they heard they are looking for the second years, but they are on a school trip right now. Kazushi drops Masaru's name, but that causes the delinquents to laugh as they reveal Masaru is their errand boy. Masataka's gang then proceeds and beats Takuya and his friends, and tell them that they are not soldiers in Tokyo Manji Gang. Beaten up, they head home, but on midway Takemichi leaves them to go visit Hinata.

The next day, after Takemichi looses in Masataka's fight club, Takuya approaches him and wonders how he lost against that opponent, but Takemichi just apologizes. They meet the rest of the gang and get into the bathroom. Atsushi reveals that there will be another fight club today and Takuya will participate. That surprises everyone as Takuya is fragile and not a good fighter, but can't do anything as its Masataka's orders. Atsushi would even take his place, but Masataka won't listen. Takuya states he will win and tells Takemichi to treat him so gyudon. The rest give their support to Takuya and leave for the fight club.

Takuya faces Kojima from the Sakura Middle School, with odds 4 to 6 in Kojima's favor. Just before the fight starts, Takemichi interrupts it and challenges Masataka to a fight. Eventually Manjiro Sano and Ken Ryuguji show up and beat Masataka, while take a liking to Takemichi. Takuya and the rest then are happy that Takemichi became friends with Toman leaders and imitate Manjiro and Ken and what they said.

After Toman gets in conflict with Moebius and Takemichi spends sometime in the hospital, Kazushi and the rest visit him at home. They are surprised to see Ken coming in too an as Manjiro also shows up, Manjiro and Ken ends up fighting.

On August 3rd, during the festival, Atsushi receives a call from Hinata, who informs him the situation with Ken. Atsushi then gathers Makoto, Takuya and Kazushi and head towards the festival. They manage to come in time and stop Masataka's gang from attacking Takemichi and Ken. They get easily beaten up, but inspired by Takemichi challenging Masataka to a fight and not giving up, they refuses to give up and continue standing up against Masataka's gang until the ambulance arrives.
