Down the alley, a masked gang creeps through the streets armed with...paintbrushes? They find their target and begin their work of tagging the walls. They finish, and leave as quickly as they came.

Jin, Mugen, and Fuu are at the counter of a restaurant going over the menu. Mugen has his face planted in the menu and Fuu is deciding. Jin orders seafood, and Mugen unable to concentrate. Instead, he says he will have the same thing. Fuu picks up that Mugen always orders the same as Jin all of the time. He says he cant understand. She concludes that he cant read.

He points to a letter and says it's a "no," and points to another one. Fuu quizzes him about "me" and he gets it wrong. Fuu makes fun at his expense, but Mugen blows it off. She and Jin share a laugh.

Just then, a wild drunken man grabs Mugen and puts him in a headlock. He exclaims that words have a soul and emotion. Mugen is an idiot and will always be one. Then,...he passes out on the floor.

The owner shows Fuu the bill and they're short of cash. Jin heads out and Mugen says to add the bill to the drunken man's tab. No problem. The owner wakes up the man and shows him the bill. He's furious.

Along the street, a curious man examines some street graffiti before it is painted over by some cleaning people. He inquires about the artists, but the cleaners scream at him.

The trio are in the street. Jin interupts that he has an old friend to see. He lives in Mihara and helped him out one time. Jin says Mihara is a sacred place for excellence in the martial arts. There are 50 dojos, and he goes on to talk about Niwa Juunosuke dono. Fuu has heard enough and tells him to just leave and ask them about the Sunflower Samurai.

Mugen is stairing at the graffiti. Fuu says that she can teach him to read. She reads the numbers that sound out "remember me." However, in a flash, the drunken man whisks Mugen away.

Jin arrives at Gojuu Hall to find it tagged with graffiti. A street gang wanders up and demands Jin to get off their territory or pay a fee. He teaches them a quick lesson, and they learn to give him some respect. He inquires about Niwa-dono. They say that "the heads" are on the side.

Fuu comes upon a large crowd in the street. Two "simalar" men are arguing about who is "the head." They say that they are brothers and clash their weapons. Fuu interrupts them, and the gang turns their attention on her. Momo-san gets defensive and hisses at the heads.

The brothers attitudes suddenly turn comical as they have fallen for her beautiful eyes, sweet voice, and button mouth. Fuu is taken back by their appeciation. The brothers then say that they will fight for her. Jin arrives and says "its been awhile Tatsunoshin, Kazunosuke." They halt their fighting and are in awe to find Jin-nii.

The drunken man dumps Mugen down, and Mugen draws his sword. The man introduces himself as Bundai. He says this is a school and will be referred to as professor. He says strength is not enough to make the world stop. You need the tools to get there. Mugen's friends do not give repect to an idiot. And, Mugen agrees to learn.

Jin tells the brothers that they should master the path laid out by there father. The should settle their battles with swords out of respect for the Gojuu Hall. But, they are arrogant and fight like brothers do. They dont want to be forced to field a sword. Tagging is more honorable.

Jin disregards their passion to create, so Fuu says that they should have a tagging competition. Who ever paints in the most dangerous spot wins. They ask for a prize and stare at Fuu. She blushes.

Bundai teaches Mugen with hard discipline. He should appeciate the curve of the letters. Bundai says he will not bother listening to Mugen's excuses.

Jin and Fuu are walking to pay their respect to Niwa-dono. Fuu says it's unlike Jin to intervene like this. But, he tells her that their father once helped him out.

Jin and Niwa-dono are sparring. Niwa-dono says he has nothing left to teach Jin. He should return to his dojo to "walk" his path. Niwa-dono requests that Jin should look after his sons if anything were to happen to him.

An old priest appears to find Jin and Fuu at Niwa-dono's grave. The priest says that their offering is very warming, even if though its not much. Jin asks what happened to Mihara. The priest said jealousy was the motive. The surrounding dojos were jealous of the Gojuu Hall's skill. They complained until the the feudal lords intervened. Rather than give up his dojo, Niwa-dono took his life so that his sons would inherit it. However, his son's were not old enough to understand the importance of the dojo.

Bundai now test Mugen with rapid fire learning, until he has finally learned to read. He tells Mugen to go out and show off his magnificent talent. He returns to Fuu, and she tells him how terrible it is to have two men fighting over her. They are going to have a tag war, and this sparks a note with Mugen.

The gangs hit the streets with their scribbling. They mark walls, bridges, bells, shrines and statues. But, the police are always one step behind. However, the winner cannot be decided, because they tag the same spots. Hiroshima Castle is the one place that they dare to tag.

The gangs now target the castle. Some members are caught, but the brothers move farther up the castle tagging story by story. Jin says that tagging Hiroshima castle is the brothers way of revenge for their father. The public disturbances attracts a large crowd. Bundai screams from below that the letters are wrong. The brothers near the top to find someone already there.

Mugen has already reached the top and has tagged the castle with his own art, an infinity symbol. He acknowledges his victory and flees.

Fuu asks who won, but the brothers said that they lost to someone else. They now realize that the world is a big place and there will always be someone better. But they still want their prize!

Momo-san appears and dances around the boys. They were talking about how cute Momo-san was the entire time, not Fuu. Jin's look is priceless.

However, the man from the street arrives with his own crew. He loves the brothers style and wants them to create fashion with him. The man introduces himself as Uhori of Andouya. But, Bundai gets to the boys first. They plead that their grammer is art, but are taken away.

The next morning Fuu wakes to find that all their belongs have been tagged with their own names (even Momo-san). They confront a jubilant Mugen. Jin asks what the infinity sign means. He says it stands for Mugen.

The two boys made a fresh wind in the fashion industry. Their styles reached the entire country. They were known as "the Charismas of Scribbling."

Notes:
The Japanese edition begins with a continuation theme from the first season. Jin, Fuu, and Mugen are simulated in a drive through theater watching the past episodes in B&W. They're in a convertible and you can only see the outline of their heads. They talk about the title and Jin tells a recap for newcomers.

The story begins in Aki, which is the former name of Hiroshima.

It's apparant after the drunken man that the episode is about writing. Otherwise, Mugen would have clobbered the man or killed him for messing with him.

One of the gang members has a butterfly knife.

The brothers must be twins, because one brother says that he is older by one minute. They however give much respect to Jin and call him their brother.

Fuu tries to hide her vanity that the two brothers are fighting over her.
