First, I wish to say Happy Birthday to Yurichan220! Hope today was a good one and many wishes! Secondly this is a story she asked me to make for her and what kind of friend would I be to say no?
So for those who play FGO, the story takes place before the Imaginary Scramble event, the Ooku Labrynth event, and Lostbelt 4. A minor deviation will be in Kingprotea's abilities for this story but hopefully, it's one that can be overlooked.
Chaldea was unique in how it could summon and house dozens of Heroic Spirits. From mythological figures like Artoria Pendragon, Gilgamesh, and Cu Chulainn to historical figures like Vlad the Impaler, William Shakespeare, and Minamoto no Yoshitsune.
With each new adventure, came new data that allowed to summon more allies to fight singularities. But the pseudo singularities and Lostbelts were something entirely else, and the data and servants they could summon led to massive extremes. The Russian Lostbelt allowed Chaldea to summon the first Tsar, Ivan the Terrible, as a giant titanic icy monstrosity with enough power to level mountains. From the Nordic Lostbelt came the Norse goddess, Skadi, summoned in with the body of Scathach, Cu Chulainn's mentor, and showing prowess with rune magic beyond normal mages. And recently from the Chinese Lostbelt came Qin Shi Huang, the first emperor of China, summoned as the ultimate life form, the perfect human.
In the summoning chamber, Ritsuka Fujimaru, the master of the Heroic spirits, and her helpful kouhai, Mash Kyrielight, were bringing forth a new servant. Recent data from the Moon Cancer BB had allowed them to bring forth a new Alter Ego and now they were trying their shot. The summoning circle started glowing with rainbow lights, and three circles appeared.
"Oh boy! Here she comes!" Ritsuka proclaimed happily as Mash could only watch in awe. The next second, the circles vanished, and light swept through the room, blinding the two girls. Once the light faded and Ritsuka and Mash opened their eyes, they went wide with shock.
"Holy crap!"
"She's….SHE'S HUGE!"
What appeared before them was a titanic sized girl that sat down with her hands wrapped around her knees, with long purple hair and matching eyes, covered in bandages and several patches of what appeared to be green…data? Vegetation? Both didn't know but the Titan smiled gently as she looked down at them.
"Master….Master….Alter Ego, Kingprotea…..Has answered your summons…."
Shaking the shock out of her, Ritsuka smiled as she pat Kingprotea's foot. "Welcome to Chaldea, Kingprotea. I am Ritsuka Fujimaru, your master."
Carefully, Kingprotea picked up Ritsuka as the Master came face to face with the titan, earning a quiet giggle when master extended her hand. She used her free hand to extend a finger for Ritsuka to shake.
"Thank you for answering the call. It means a lot to us."
"And thank you for summoning me, Master."
Thanks to Sion and Captain making adjustments to the base, servants of Ivan's size (Primarily Xiang Yu and Darius III) could move around easily but Kingprotea was a special case as Ritsuka and Mash would discover. While her primary form was huge, she could easily shrink herself down to a normal size, though warnings from BB told them she could grow exponentially if they weren't careful. For the moment, Ritsuka and Mash were showing Kingprotea around and getting her acquainted with the facility.
"How are you enjoying the tour, Kingprotea?" Ritsuka asked.
"I am…It's nice to be someplace outside my containment field in the Moon Cell…" Kingprotea answered as she waved to several passing servants. Some waved back, some just nodded in acknowledgement, and others would ignore her. While it made the Alter Ego a bit disappointed, the first two outweighed the last group. The sound of childish laughter caught everyone's attention as a group of Chaldea's youngest servants came charging down the hall, with Jack the Ripper in the lead.
"Hi Mommy!"
"Hey Jack!"
Ritsuka lifted the young serial killer in a hug as Mash waved hello to Nursery Rhyme, Jeanne Alter santa Lily, and Paul Bunyan.
"We were showing the latest servant to be summoned around. Care to say hi?" Ritsuka asked to the girls. All responded with a cheerful 'Hello!' to Kingprotea, who could only smile and wave.
"This is Kingprotea, an Alter Ego. She can grow to HUGE size like Paul and I bet she would like it if you would be her friend." Ritsuka said as she nudged the Sakura servant to go with them.
"Can she?!" Jack asked excitedly as she bounced on her heels.
"She can be our friend!" Nursery Rhyme declared happily.
"Come on! Come on! Let us show you the rest of Chaldea!" Jeanne Alter lily Santa cried as she took Kingprotea by the hand. They all scampered off, with Paul staying behind.
"Something wrong Paul?" Mash asked as the lumberjack shook her head.
"Non, nothing is wrong Mash. I'm just happy that we have another girl who's like me." Paul answered back with a smile. Ritsuka pat her on the head.
"Paul, I have a very special task for you. Help Protea feel welcome. I think she'd love having someone who's like her." Ritsuka suggested. Paul could only brighten up as she ran off to catch up with her friends.
"GAAAAAAAAAOOOOOOOO!"
The children screamed in faux horror as they ran from the 'giant monster', barely containing their laughter as they ran with Kingprotea happily chasing them. They'd found a nice space to play in and they were taking advantage of that and true to what was said, Protea grew big to play. It didn't take long before the super-sized Alter ego captured Nursery Rhyme in her grip, though the caster giggled.
"Help! Save me from the Giant monster!" Nursery Rhyme cried out as Jack and Janta tried to 'save' her and 'attack Kingprotea's ankles, doing nothing.
"Wahahahaha! Tiny humans! You can't hurt me!" Kingprotea jokingly gloated as she carefully stomped the ground to knock the two attackers down. "No one can stop me!"
"RAAAAAAAHHHH!"
Kingprotea felt arms wrap around her, releasing Nursery Rhyme, and seeing that it was Paul Bunyan, now equal to her size.
"Nobody hurts my friends, monster!" Paul carefully threw Kingprotea to the ground, the latter eliciting an 'Oof!' as she crashed to the ground, the two wrestling as Jack, Nursery Rhyme, and Janta cheered her on.
"Go Paul!"
"beat the monster!"
"You can do it!"
But Kingprotea wasn't going to be beaten that easily. In the struggle, Kingprotea managed to get off the ground and get atop Paul. For the first time in a long while, the Alter Ego was enjoying herself as she wrestled with the Berserker class servant, the two laughing as they brawled.
"YOU'RE GOING DOWN, PROTEA!"
"BRING IT BUNYAN!"
The giant girls grappled for the last time, both doing their best to try to get the advantage over one another. Both could feel exhaustion and eventually Kingprotea tired out first. "You win…" and the giant Alter Ego tumbled down, though forgetting to let go of Paul's hands, brought her down with her.
"WHOA!"
"HUH?!"
The two were in a heap as Jack, Nursery Rhyme, and Janta all looked on in worry. As they got a better view, they saw that Paul and Kingprotea, in their collapse, were kissing, leaving all in surprise. The two large girls were blushing as their lips locked, with Jack, Nursery Rhyme, and Janta also blushing, with the latter two covering their mouths.
"L-l-l-lewd!" Janta cried as she pointed and her face as red as a tomato.
"Is it just like the fairy tales?" Nursery Rhyme asked no one as different fantasies began forming in her head
"Their kissing…like a prince and princess…." Jack quietly said. The two large girls eventually broke their kiss as Paul backed up.
"S-sorry, mon Cherie….May I?" Paul held out a hand for Protea to help her up, which the Alter ego accepted as she got up, though looking away in embarrassment.
"T-thank you for the fun Paul…Umm…"Kingprotea had no idea what to say or do, and neither did Paul.
"Wanna play something else?" Jack asked?
