Funabashi Arc Edit

Nozomi Kaminashi vs Funabashi

Rio and her comrades confronting Nozomi in the finals.

The night before the preliminaries of the Gulf Coast Cup, Rio appeared inside the Funabashi Keijo Stadium. She told Yoshinaga to take a bath immediately. Confused, Nozomi Kaminashi asked to Yoshinaga who she was. In turn, Yoshinaga explained about Rio.[1] After the preliminaries, Rio was taking a bath, accompanied by Aota and Kigawa who washed her butt. Before leaving, she warned Nozomi about how to survive. The next day, Rio and Kigawa oversaw Nozomi when the Hyougo Branch player defeated Doi.[2] The next day, Rio and her comrades, consisting of Aota, Kigawa and Mitsuko Hoshi were advancing to the finals. Rio was surprised that Nozomi managed to reach the finals. As the match started, Nozomi assaulted Rio with her "Meteor Hip". However, Nozomi was unable to push her at all, realizing how strong Rio was. Spininig her boobs, Rio decreased the temperature of the "Hot Smoker" Land type, creating a huge amount of fogs to trap Nozomi.

After Nozomi was assaulted by Aota, Kigawa and Mitsuko, Rio praised Nozomi since she was still able to hold off. When Nozomi declared that she wanted to take down the Five Butts, Rio laughed out loud before landing a fatal blow onto Nozomi's backhead. Along with Aota, Rio tried to finish Nozomi off. However, both of them were ambushed by Kazane Aoba.[3] Rio questioned if Kazane wanted to talk about the dreams that couldn’t be attained so easily. In turn, Kazane stated that nothing could change if they didn’t take a try. Realizing that it’s pointless to talk with both Kazane and Nozomi, Rio was pissed off and blew Kazane away. After Aota and Kigawa prevented Nozomi to move, Rio assaulted her with the "Water Moon Killer". Despite this, Nozomi was still able to survive. Shortly after, Kazane returned to rescue Nozomi, and both of them were able to defeat Aota. [4]

After Mitsuko was defeated by Nozomi, Rio recalled her past when she was hospitalized. Ripping off her bikini tops, Rio revealed her K-cup boobs and overwhelmed Nozomi by using them. When she was preoccupied by Nozomi, Kazane prepared an ancient technique she obtained by scanning a pharaoh's butt. [5] When Kazane used the "Neith Butt Bolg", Rio was surprised since Kazane was perfectly able to dodge her attacks. Kazane revealed that her technique wouldn't be avoided as it always targeted the opponent’s crotch. When Kazane was about to finish Rio off, Kigawa stepped between them and protected Rio. After being defeated, Kigawa asked Rio to defeat both Kazane and Nozomi. Rio then lured Kazane to attack her crotch before countering Kazane with her gigantic boobs, defeating Kazane. This made Nozomi realized that Rio was risking her life to win.[6]
