Chapter 2: That Man, Like A Dragon
Phoenix and Maya are stuck in front of Club Sega in a monster-infested Kamurocho, which has been sealed off by a set of walls (to keep the monsters inside). They are to meet with their newest client, but are cornered by a couple of zombies. Then their client arrives and saves them. Heihachi Mishima (Tekken) says he's being framed for the happenings in Kamurocho and he wants Nick to prove his innocence. Majima (Yakuza) arrives too, demanding to know who's behind the chaos in Kamurocho, to which Heihachi answers it's Shadaloo (Street Fighter). Majima knows Nick and Maya, as Nick has represented the Tojo Clan previously and even helped prove Majima's innocence. Reiji and Xiaomu of Shinra arrive as well as Jill and Chris (Resident Evil) and finally the Dragon of Dojima, Kiryu (Yakuza). They tell Phoenix and Maya to hide in the sewer while they take care off the monsters. After the fight, Kiryu tells the group about an urban legend that the manhole Phoenix and Maya entered connects to another dimension, and indeed, the two aren't there. The group enters the manhole to save Phoenix and Maya.

Chapter 3: The Family Together, And Turnabout
Phoenix and Maya find themselves in the Demon World, where they arrive just as Demitri and Morrigan (Darkstalkers) are about to fight. Morrigan offers to send them back to the human world. Meanwhile, Heihachi Mishima finds his son Kazuya Mishima and grandson Jin Kazama (Tekken) in the Demon World, who are about to fight, but they get surrounded by demons. Reiji, Xiamu, Jill, Chris, Kiryu and Majima arrive to fight off the monsters.

It's then that Demitri and Morrigan arrive, together with Phoenix and Maya. Finally, Bulletta/Baby Bonny Hood (Darkstalkers) also pops up, saying she's here to kill Phoenix. Bulletta is hired by Shadaloo to kill Phoenix, so he can't defend Heihachi (and it's easier to kill Phoenix than Heihachi). There are too many monsters, so the fighters can't send Phoenix and Maya away. Morrigan notices Maya's magatama, and says she'll infuse it with demon power. She orders Maya to infuse the magatama with the wish to become stronger (Maya wishes she'll be as strong as the Steel Samurai and the Pink Princess, and for Nick's "objection" to be able to hurt the monsters), after which Morrigan infuses her demon powers in the magatama, making Phoenix and Maya available for battle (as support characters to Demitri and Morrigan). After defeating Bulletta, Reiji thinks it's wise to have Shinra take custody over Phoenix and Maya.

Chapter 31: Dancing Turnabout
The heroes arrive at the Dragon Palace, where they discover they've been too late: the Golden Seed has been stolen from the Dragon Palace. They find Tarosuke (Youkai Douchuuki) in front of the palace, argueing with one of the bad guys. Apparently, Otohime had the complete palace sealed the moment she noticed the Golden Seed was gone (making it only possible for people to enter, not to leave), and none of the bad guys managed to escape before that. From the conversations between Shadow (Space Channel 5) and Sigma (Megaman X), we learn that they apparently already managed to send the Golden Seed away before the place was sealed however.

Otohime declares that nobody is allowed to leave the palace until the whole deal is cleared up, when one of the bad guys accuses the heroes of having taken the Golden Seed. Otohime conjures up a courtroom in the Dragon Palace court, and the heroes ask Phoenix to defend them. In the meanwhile, Tarosuke has gotten Edgeworth from the human world, and he is to do what he's best at: prosecute. Court is about to open when a decisive witness appears on the scene, who clears the whole thing up. And then the battle begins.

After the battle, the heroes (and Edgeworth) are invited to a party in the Dragon Palace. The next day, the heroes leave again, and Tarosuke mentions that Edgeworth was still sprawled over the floor and that he'd send him back home when he'd get up.

Dammit, Edgeworth. Is this how you act with children around? Use some discretion, man! >:C

Yet, I can't help but get the feeling that Dante had something to do with it.

All the girls in a hot spring!

What the heck did Tarosuke say to Edgeworth that convinced him to show up in a place like this!?

And I get the feeling the real reason Otohime summoned him was so she could be a good hostess... for the party.

"Golly, I get to follow a mysterious young boy to a differrent world to prosecute, with Phoenix as my opponent? Count me in!"

Why he showed up for the epilgue, that's a riddle...

Is that KOS-MOS on the left there?
