Unable to withstand his sisters' teasing any longer, Yu-yu ran away from home and was brought to an abandoned amusement park by a member of Team Blackout. And that is also where Danji is aiming to get his 20th consecutive win, with Tohya standing in his way for that record.

It's the anniversary of the day Megumi and Danji met. However, Danji shows no signs of any intention to celebrate it, and seems to have completely forgotten about it. Seeing that Megumi has started sulking in disappointment, Tomari takes action to lift her spirits.

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.

Urara is unable to focus on the fight because of the "annoying sounds", and wishes to hear the sounds she heard when she first fought with Yu-yu once more. Mirei, her opponent, comes to understand Urara's feelings. Sounds heard by the heart, and lights seen by the heart. A real fight between the two begins.

Final match of Deluxe. Yu-yu, who never forgets to "enjoy the fight" no matter which strong opponent he faces, and Raika, a genius who values winning above all else. The fight between the two with different beliefs leads to a development beyond imagination. Who will be known as history's strongest fighter?!

Uniformers is a group that trains on the basis of data with the goal of having the "Ultimate Fight". Urara hits it off with one of their members, Halona. And the person Halona introduced as one who knows true power is none other than the organiser of Deluxe, Jinki Mukae.
