Previously, Tama challenged Aoi to a GunPla battle after Aoi's completion of the two kits that was given to her by Mika, which are the High Grade Gundam the Origins Zaku II (Red Comet ver.) and HGUC Zaku III respectively. Before the fight, Aoi confesses it will be her first time doing GunPla battle. Both friends were shocked by this fact as she was a GunPla contest winner. Aoi, however, explained to them that she hated the idea of GunPla battle before. Now with an open mind, she fights Tama with her Zaku II.
Meanwhile, an old man watches them from the shadows... with the battle taking place reminds him of a past. He continues watching, reminiscing the past with each blow dealt.
Tama: "You have good control, despite it's your first time! Come on!"
Aoi dodges Tama's fast beam rifle shots
Aoi: "Tsk... can't find a good angle to fire. She's too fast!"
Aoi tries to aim at Tama, but her shots were always countered with beam rifle shots. Seem to be losing her ground, she tries a hit and run tactic.
Tama: "Stealth huh... Too bad Aoi, you are red! I'll find you-"
Before she reacts, Aoi fires a bazooka shot on Tama, who got surprised.
Aoi: "How do you like them apples?!"
Tama smirks
Tama: "Not bad! Not bad! Hahaha!"
Mika: "Hey Tama! You better up your game! Hahaha!"
Meanwhile on the shadows, the old man watches really intently with a huge grin on his face.
???: "Mmmm..."
Back in the stadium, the battle taking place becomes hotter. Tama keeps on taking hits while she figures out where Aoi was hiding. Meanwhile, Aoi is on her last bazooka ammo. She aims at Tama, but suddenly-
Tama: "There you are!"
Aoi: "Shoot!"
The beam from the ReGilis's beam rifle destroyed the Zaku II 's bazooka, causing Aoi to immediately leave the area and find another hiding spot. However, Tama now knows her tactic. Running out of ideas, she attacks Tama, guns blazing and with Heat Tomahawk in hand.
Tama: "And you expect to damage me with a pitiful Heat Hawk?"
Aoi: "Well, with only a Zaku II, what can you expect?"
Aoi strikes Tama with the heat tomahawk, but it was deflected with a beam saber. Afterwards, the Zaku machinegun is destroyed too. With only the anti-ship rifle left on her arsenal, she starts hiding again, this time teying to be as far away as possible, hoping to use the weapon like a sniper rifle.
After a while she finds a good spot and positions herself, ready to aim at the ReGilis from afar. Finding Tama on her sights, she aims at her beam rifle. Aoi manages to hit the weapon, causing it to explode. She then aims at the ReGilis's chest, but Tama blocks it with her arm, hitting her GunPla's arm joint. With only 2 more ammo left, she aims again at the Regilis's chest, but it soon found her.
Tama: "whew... unbelievable... To think you would damage me this hard with just a friggin' Zaku II..."
Aoi: "Welp. I guess I am dead."
Mika: "Hahaha! Good game!"
With its good arm, the ReGilis stabs the Zaku II with a beam saber.
Machine: "Battle ended."
Aoi: "Whew... Tama has a wicked GunPla!"
Tama: "Hehe! But seriously, if I had not kept my wits, you would have destroyed me."
Mika: "Yeah. Your tactics maybe a little bit... tacky, but it really works. And the way you handle the sniper is awesome! I actually suck at super long range attacks."
???: "Yes indeed! I am surprised how you handle the anti-ship rifle like a sniper."
Everyone is surprised.
Mika: "W-who are you, old man?"
Aoi: "Must be a creep! Call the police!"
Tama: "Hello? I like to report a-"
???: "No! You're wrong! I am not a creep! I am simply... a man with a passion for GunPla!"
Everyone stays silent.
Tama: "Hello? I like to report a-"
???: "Oww it breaks my heart... I guess the people really have forgotten about me."
Aoi: "Wait a second..."
Aoi scans the old man. She looks at him and then-
Aoi: "...are you perhaps the old man I met years ago?"
???: "Ah! Aoi Takanashi! You remembered!"
Aoi: "Hmmm... AHHHHH! You are that weird guy who kept bugging me to do GunPla battle! I think your name was Tats... Tatsu..."
Mika: "Hold on... You mean to tell me this guy IS TATSUYA YUUKI? THE FORMER MEIJIN?!"
Tastuya: "Well, yes! So good that someone still remembers my name!"
Mika: "Why are you gone for so long? Everyone thought the former Meijin died!"
Tatsuya removes his glasses and gives the girls a melancholic look.
Tatsuya: "I...I just simply wanna live my remaining time here with my family. I do take guest appearances on GunPla contests, but I rarely do it nowadays. I also come to Seiho Academy and here often, just reminiscing the old times."
Mika: "Ummm... I am sorry."
Tatsuya puts his glasses on and gives Mika a smile
Tatsuya: "It's alright. Sharing my story to the younger generation takes stress off my chest."
Mika smiles back, sighing in relief. Tatsuya then turns towards Aoi and approaches her.
Tatsuya: "Aoi."
Aoi: "Yes sir?"
Tatsuya: "How about you three... fight me, hmm?"
Shocked, the trio looks at Tatsuya Yuuki in confusion.
The three: "EHHHHHHHHH?!"
Tatsuya: "Mmmhmmm. How about you give this old man a good time? Anyway, Aoi, you were testing the kits you built, right? Can I borrow the other one?"
Aoi: "The Zaku III?"
Tatsuya: "Yeah. I might teach you guys a thing or two!"
Aoi hands over her Zaku III to Tatsuya and the three prepare to fight him.
Machine: "The other player requires 2 more other players. Are you sure you want to continue?"
Tatsuya: "Absolutely."
The three: "gulp..."
Tama: "You guys realize we are about to gang up on an old man, right?"
Mika flickers Tama in the forehead
Mika: "Do not underestimate him. He maybe old, but he's the former Meijin Kawaguchi. Whatever GunPla he controls, he can certainly destroy everyone with it."
Aoi: "Interesting. I hope you teach me a lot of new moves, old man!"
Tatsuya snickers and pulls his hair upwards
Tatsuya: "Hmph.You youngins shall know the power of Meijin Kawaguchi!"
Machine: "All systems go. Beginning Plavsky particle disposal. Field 4, desert. Please set your GunPla."
Tama: "Mmmhmmm~"
Mika: "..."
Aoi: "Hehe."
Tatsuya: "Hmmmm..."
With all eyes set on each other, they now position themselves.
Machine: "Battle start!"
Tatsuya: "Tatsuya Yuuki, Zaku III, let's go!"
Tama: "Tama Ebikawa, ReGilis, here I go!"
Mika: "Mika Okuwara, Tallgeese Flugel, coming through!"
Aoi: "Aoi Takanashi, Zaku II, let's do this!"
With all the GunPla on the field, Aoi and her friends plan their attack on the former Meijin.
Aoi: "Should we attack him all at once?"
Tama: "But then we'll win quick..."
Mika: "No. Bad idea. We don't know what kind of tactic he will employ on us once we gang up on him. For sure... he's out there anticipating our move..."
Out of nowhere, a stray beam attack hits the ReGilis in the shoulder, damaging its armor.
Mika: "Watch out!"
The Zaku III speeds up above them, raining fire on the girls.
Aoi: "THAT WAS CRAZY!"
Tatsuya, snickers, and his Zaku III starts raining fire on the girls again.
Tatsuya: "Haha! Don't be too careless now."
Ratsuya fires another volley of shits against the three. The trio tries to get away, Tatsuya won't let them go.
Mika takes the skies and attacks Tatsuya with the Tallgeese Flugel's lance. She misses and Tatsuya counters her by kicking back to the ground. Tama then fires at him, but he was able to dodge and returns fire. They both Aoi and Tama tries to aim at the Zaku III, but Tatsuya's handling make it seem an improved suit. He returns fire again, Tatsuya was able to hit ReGilis's beam rifle, causing to explode. He comes in towards Tama using a beam saber, but she counters back using the guns on her legs. She then pulls her beam saber and defends herself from Tatsuya's attacks. Unfortunately, Tatsuya was able to overwhelm her, stabbing his beam saber to the ReGilis's chest.
Tama: "... wow. He is scary. Scary good."
Mika: "Ungh... Now we're down to two! Gotta get up!"
Aoi: "Sorry.... Couldn't do anything."
Tatsuya: "C'mon. you two!"
Both: "rrrrgghhh!"
Aoi helps Mika back up. However, the Zaku III relentlessly unleashed more barrages. Tallgeese Flugel eventually came back and fires its dober gun to Tatsuya. He manages to dodge it. Mika fires again, but she cannot hit him. Aoi uses the anti-ship rifle to bring Tatsuya down. She manages to hit, but it wasn't enough. Charging at Aoi with a beam saber, he cuts her down. Lastly, Mika, unable to fight, the Tallgeese Flugel simply just falls from a beam rifle shot.
Machine: "Battle ended!"
Tatsuya: "Well, how was it?"
Aoi: "I... really didn't even dealt that much challenge."
Tama: "We got wooped."
Mika: "sigh... That was really scary."
Tatsuya: "Hahaha! Glad to see you enjoy yourselves."
Aoi: "I feel the love for GunPla in that fight. Even if it was just a straight build-"
Tatsuya: "Everyone can win with a straight build. Aoi, the Zaku III you built was made with love, just like your Zaku II. Now that I won... Just gonna ask, are you guys planning on coming to the next tournament? Are you coming in as a team, or-"
Mika: "Aoi... will represent the team."
Aoi: "Eh? EHHHHHHHHH?!"
Tama: "It's a good opportunity for you to gain more experience."
Mika: "I am confident you can. We just need... practice."
Tatsuya comes near the girls and offer them his help.
Tatsuya: "I will help with practice. I will coach Aoi here with the best of my abilities. You rejected my offer before Aoi, but this time, I hope you reconsider. I saw a potential in you and I want to help you grow it."
Shocked, Mika asks if Tatsuya can tutor all of them.
Tatsuya: "Hmmm... Maybe sometime. I want to focus on your representative. However, I want you guys to always stay with Aoi whenever I coach her."
Aoi then comes forward
Aoi: "I accept. I won't let my friends down!"
Tatsuya: "Good! We'll start tomorrow after your school. Anyway, I think it's getting late. Let me take you guys home."
Everyone: "Thank you very much!"
And so, Tatsuya gets each girls home. Saying their goodbyes, Aoi declares that it was a rather fun and fulfilling day. When Aoi got home, she can't stop talking about what happened to her mother. This fateful encounter is the true start of Aoi to her Build Fighter career. With the former Meijin teaching her the ropes, Aoi will surely soar.
