Yuuna was getting ready to go home, when she found a note in her locker. It read, "Meet me at the arena. Bring your Gunpla." "Why would someone put a note in my locker? Is this a challenge?" She went to arena and it was packed. She walked around hoping she know who was looking for her. "Hey Yu." Only one person called her by that name. She turned to find a girl with orange hair tied in a ponytail. "Oh hi Rio. Do you give me the note?" "Yeah, I want to fight you." "Why didn't you just ask me?" She shrugged. "Just more fun that way. So are you ready?" "Yes." They went to a machine and it started up. "Field 08: Sky. Please set your GP Base. Please set your Gunpla." They set up their Gunpla are their eyes let up. "Yuuna Kazaraki, Astray Elite, showtime!" "Rio Sakaki, Zeta Gundam 'M', launching!"

They both flew into the field, which was the sky with some clouds and floating masses of land. Rio's Gunpla was sporting a orange and black paint job. "It looks like you put alot of work into it Rio." "Impressed are we? Well let me show you it's power!" When she charged at Yuuna it caught her off guard. Astray was knocked back far. "Man, she wasn't kidding. Well, it's my turn to go on the offensive!" Yuuna took out a rifle and started to fire. Rio used her shield to block some shot before it was destroyed. "My chance!" Yuuna took out her beam saber and charged to Rio. "You got to better than that!" She dodged her attack, then took out her saber and cut one off Astray's leg off. "What speed!" "Man, I was close." The Astray transformed and flew away. "You can't escape from me that easy!" The Zeta transformed and flew after it. "What! You can transform too?!" "That's not the only thing!" "The Zeta launched a wire from it to the Astray's wing. "This maybe a shock to you!" It suddenly unleashed an electrical current. Yuuna's pit turn yellow.

The Zeta transformed and started to swing the Astray around. Yuuna was having trouble breaking free from it. Then before she knew it, she was thrown towards land. The Astray didn't have much energy left. "I have to admit, she's good but I won't go down easily." She tried to move the Astray but it didn't move. "Dang it, not now." Zeta was charging at it with a saber. "This is it!" "I won't let it!" The RG system activated, allowing the Astray to dodge it. After the Zeta strucked the ground, the ground was destroyed. There were pieces of rock flying everywhere. And the Astray was nowhere to be found. "Where did she go? Come out and fight Yu!" At that moment, there was a blade sticking out of the cockpit area. "I'm right here." She took the blade out and the Zeta fell. Rio's cockpit turned off. "Battle Ended"

The field disappeared and the machine turned off. The girls went to get their Gunpla off of the machine. Rio sighed. "Looks like you beat me again Yu." "I did, but it was barely. You have gotten alot better." "Well, I have to become stronger to beat my rival!" "I guess so." Rio remembered something as she saw the time. "Oh, I have to get going now! I'll see you later!" "Alright then. Bye!" "Bye Yu!" Rio left the arena in a hurry. " Looks like she never changed. I guess I'll go too."

She was walking home and she decide to give Sho a call. " I wonder if he fought someone today." He was working on Future when she called. "Hello?" "Hi Sho." "Oh hi Yuuna. What's up?" "Just finished a battle." "Did you win?" "Yeah, but the Astray's totaled." "I feel ya. Same thing with the Future." "Oh wow." "Yeah." "Can you fix it?" "Yeah, actually that's what I'm doing now." "Why doesn't that surprise me?" "Beats me. Do you want to bring the Astray in?" She thought on that for a moment. "Sure. That will be fine." "Great! We can work on it after-school tomorrow." "Uh-huh sure." "Okay then. I'll see you tomorrow." "Okay then. Bye." "Bye." After they hung up, Yuuna's face turned red. " W-w-why does my face feel warm?!"
