Raika receives an invitation and has a choice to make. Meanwhile, Urara misses her stop and finds herself alone. Until Megumi takes her to the nearby amusement park, that is.

"Deluxe", the tournament that would decide the strongest fighter commences. The opening ceremony takes place at Ariake Arena. Shortly before, the Top Fighter Michiru Hazama challenges Danji Momoyama to a fight. As two old acquaintances, what is it that Michiru entrusted Danji with?

Noteworthy battles unfold among the chosen participants at "Deluxe". Among them, is a battle between Yu-yu and Student Council President, Raika Koshiba. Yu-yu was looking forward to a match with Raika, who is an active pro as a Front Fighter on stage.

Yu-yu is overwhelmed by the serious battle with Raika. Mirei visits Yu-yu to cheer him up and brings him a gift. The next opponent is his team mate, Zakusa Ishigame. As Zakusa pushes him with his all, what is this new power that Yu-yu is clad in?!

Megumi's opponent is none other than the one known as Japan's Number 1, Michiru. Ever since deciding to participate in "Deluxe", Megumi has been determined to put in more than twice the effort and training. Megumi, inheritor to the Legend of Kaga; her will gives rise to a marvelous onslaught!

It's time for a match between Front Fighters Raika and Taizo Kiyokura, a hotshot businessman who's in to both beautiful ladies and Vanguard. Taizo is a powerhouse fighter who has a history of wins under his belt. Can the talented young Raika see the path to victory?!

Yu-yu faces Taizo with the entry to Top 8 on the line. Yu-yu, who fights while receiving support from his friends, is a fighter different from those that the cheerful Taizo usually faces. There seems to be a reason that Taizo is fighting for amidst admiration from his employees in this tournament.

After the fierce battles, fighters who won their way into the remaining 8 spots spend their time thinking before the next round begins. Yu-yu welcomes an unexpected guest, Tohya departs on a long journey, and Raika shows a new side apart from that which Urara wasn't good with.

First match of the "Deluxe" tournament quarterfinals. Yu-yu vs Urara. To Urara, it feels like a rematch of when she first encountered Vanguard. However, Urara receives support from the people around her and becomes too conscious of wanting to win, and begins to show Yu-yu an unexpected development of the fight.

First match of the semifinals has two powerhouse fighters facing off. It is a ferocious fight between fellow knights Bastion and Tohya with a "thirst for strength" against Youthberk and Raika who thinks "there's no meaning apart from winning". What lies beyond this fight, and what does Raika's Skyfall aim to achieve?

Yu-yu and Michiru face off in the second match of the semifinals. Taizo says that Michiru's loneliness is due to his overwhelming strength. Without flinching against the strongest fighter, Yu-yu has decided to proceed to the finals in order to have a rematch against Raika. Michiru discovers something amidst the fight against Yu-yu.
