Ryu is having a nightmare. He sees Akuma, and rages under the influence of the dark hadou. His own master, Gouken, briefly appears.

At a dojo, some of the walls are suddenly blown apart. Ryu walks outside, wondering about this evil ki he can sense. Is it something to do with Akuma?

The next day, Sakura Kasugano and her friend Kei Chitose are talking about what they want to do. Kei wants to go shopping, but Sakura says she can't as she's got special training to do -eating hot dogs. Someday she wants to go to America and enter a hot dog speed eating contest, and win it so she can get into the Guinness Book of World Records. Kei thinks there really is something wrong with her, but Sakura maintains she will train really hard. Nearby, Ryu is looking out at the sea. He thinks about how Akuma used the dark hadou, and killed his own master, Goutetsu. Ryu also believes Akuma probably also killed his master, Gouken.

Back at Ryu's dojo, the caretaker is sweeping up, when he sees a boy has appeared. The boy says he is here to see his big brother: Ryu!

Back at the docks, Interpol agent Chun-Li and her partner, Wallace, engage some criminals. But the criminals start using guns, and as they run past some people, Sakura thinks it's way awesome. She wonders if this is for a movie shoot.

But then she realizes that there are no cameras around. One of the criminals takes a kid hostage, and tells the cops to back off, otherwise he'll blow the kids head off. Before he gets the chance to fire, Ryu drops down and takes him out.

Ryu grabs the kid and takes him over to where Sakura and Kei are, asking them to watch over him. He then runs straight back towards another guy, who starts shooting at him. But he dodges between the bullets with ease.

Chun-Li is amazed that this guy can slip between the bullets like it's nothing at all. Ryu easily takes down another two guys, whilst Chun-Li defeats a third.

Ryu beats up the remaining men, but one manages to get back up and grab his gun. He doesn't get a chance to fire it though, as Ryu kicks him away.

Chun-Li wonders who that man was, and returns to the Interpol HQ to do some research. She finds out that the martial artists she saw was Ryu, a man who defeated Sagat, the powerful Muay Thai Emperor.

Wallace then comes in, and thinks Chun-Li is up to something naughty judging from how quickly she turned off her laptop. But he then tells her that the criminals they've caught were working for Shadowlaw. He mentions that the criminals have told them that Shadowlaw is sending large amounts of money to Professor Sadler, a biologist. And it seems that this Sadler is gathering together martial artists from around the world, in one of his labs. Chun-Li wonders if her father could also be there.

Elsewhere, Ryu is heading back to the dojo with some water, when a card falls into his bucket. Suddenly, he seems to be somewhere else, as a woman appears before him.

But she suddenly somehow manages to duplicate herself, and starts laughing. He can tell that most of them are just images, and quickly finds the real one, but he can't hit her. She tells him he certainly gets worked up easily, and thinks he's still a child. He tries to attack, but she uses a projectile attack to blast him back.

She tells him she has something to say about his future. She says that he will soon meet someone who will change his destiny, and through that meeting, he will change. Will he grasp the light, or be swallowed by darkness? Ryu says he doesn't get it, and wants to know who she is.

She says her name is Rose, and she summons a card which Ryu takes. She explains that the card is meant to call up the devil. Rose says that some people can overcome suffering and grasp their heart's desire, but only if they can overcome all. She tells Ryu to become even more powerful, as if he can overcome... before she can finish, the card vanishes, and so does she.

As the scenery returns to normal, Ryu sees that Ken has appeared. He says hi and notices that Ryu looks a little out of it. The two of them walk towards their master's grave. The devil card is still on the ground, as Rose says an interloper interrupted her. She wonders if Ken will be the trump card, or someone else.

Ryu finds out that Ken came all this way just to pay his respects to their deceased master, but he says he has some other business to also take care of. He can tell something is wrong and asks Ryu what's on his mind, but he doesn't mention it. Instead, Ryu says how their master, Gouken, was like a father to him, as he never knew his real parents. Everything he knows in life, he learnt from his master. Ken says he'll go and get some more water and runs off with the bucket.

Seconds later, Ryu suddenly feels how the blood in his body is boiling, and a voice calls out to him. The voice tells him to open his eyes to the evil hadou, which lies within him. Ryu can't tell what is happening to himself.

Ken hears an explosion and runs back, finding Ryu face down in a crater. As he tries to get him back up, he senses someone else nearby. He turns around to see a boy looking at him.

Later on, the three head back to the dojo, where Ken learns that the boy's name is Shun -and he is Ryu's brother! Shun says he's been dying to meet his big brother, and shows a photograph of their mother. The picture has the name "Ryu" scrawled onto it in the bottom left corner.

Ken thinks she's not bad looking. Shun explains that he used to live with her in Brazil, and she used to tell him that his big brother, Ryu, lives in Japan. Ken doesn't think that proves anything.

Shun says his mother also told him that she had a good reason for doing what she did, which was leaving Ryu in the care of Gouken right after he was born. Shun then says that story was all she left him -she died 6 months ago. So he came in her place.

Later on the trio have a quick meal, and whilst Shun wants more, Ken wonders why he has to eat with them. Shun says he's Ryu's little brother, so he gets to hang out with them. The next day, the three head out to a beach to train, and Shun shows that he is also a martial artist. Shun says he started to learn ever since he found out that his big brother was raised by a martial artist.

He then mentions their father, but then trails off. Ryu asks if their father is dead too, but Shun isn't able to answer that with what happened to him. Ryu says it doesn't matter -it just doesn't matter to him. Shun then challenges Ryu to a sparring match, and two start to fight in the sea.

Elsewhere, Sakura is trying to find Ryu, and runs around town bothering people. She keeps seeing potential Ryus around the place, but they are never the genuine article. Kei asks her why she went running off like that, and Sakura says it's because she's looking for him -that guy from yesterday, who wore a headband.

Sakura does a few moves, kicking one of her sneakers off in the process. She says she wants to see that man again, she just has to. She then sees another possible Ryu, and hobbles off to talk to him. Kei sighs and says she can't keep up.

Back at the dojo, Ryu and the others are on the roof, as Shun brings them some food: pork and beans. He says it was his mom's specialty, and Ken tries it. He says it's not bad! Shun wonders why they are up here, but Ken tells him to keep quiet and to enjoy the view. As they watch the sun set...

...Shun says that their mother would look towards the setting sun. She would pray, asking for tomorrow to be a good day for her, for Shun, and for Ryu, who was so very far away. That night, Ryu is looking at the picture of his mother when he suddenly feels the dark hadou again.

Ken wakes up, feeling the evil ki, and sees that both Ryu and Shun are gone. He runs outside and sees Ryu.

Ryu is screaming, and releasing projectiles. Ken avoids them and takes cover behind a tree, knowing that this is something his master told him about -this is the dark hadou.

He runs forward and punches Ryu in his stomach, telling him to snap out of it. Ryu seems to calm down, and as Shun appears, he walks up to his brother. But Ryu tells him not to touch him.

Ryu returns to the dojo, and thinks about what Gouken told him. Their style was originally used for killing. The wish to become the strongest of all... Gouken told Ryu that he must never let such a desire rule him, or allow the dark hadou into his fists. Akuma chose this path, and his hands are now stained with the blood of his own master, Goutetsu. Ken then enters, and asks why the dark hadou has started to awaken inside him. Ryu says he doesn't know. He asks Ken to kill him, should he be unable to break free from the dark hadou.

Back at the Interpol HQ, Wallace tells Chun-Li that Sadler is going to Japan. It seems a street fighting competition is being held in Kabuki Town, and the winner will receive a large amount of prize money. Chun-Li asks if Sadler will be there, and Wallace believes he will.

Back at the dojo, Ken happens to be talking to Ryu about the same competition, and how he came here to enter it. Shun then appears, and asks if he can enter the competition as well. Ken is amused by the headband he is wearing.

Shun asks if Ryu is going to fight, but Ryu hesitates to answer. Ken thinks the two of them could be his cheerleaders. Shun asks if Ryu isn't going to fight, and Ryu says he's not. Ken says he'll show him some way cool moves, but Shun pouts at him. As he does, his headband slips down over his eyes, which Ken mocks him for.

Ryu comes over, and tells him to try tying it again. He takes his own headband off, then puts it back on. He says that that he always asks himself a question whenever he does this...

...is he worthy of this fight? He asks Shun if he understands. Shun ties his headband back on, and looks at his brother.
