My youth story, a crossover anime, turns out, is FGO!

(I'm not really inspired, so I'll just write another side story first. This side story is a happy ending that ignores all logic, meaning that the Servants didn't leave and formed couples with the Masters. There are no alternate identities; they were all summoned. As for Makoto Aoki, he's currently in a lazy state and hasn't finished his next project yet.)

"So hot……"

Makoto Aoki slumped on the recliner, completely exhausted and unable to lift a muscle: "Why would anyone like summer? It's totally illogical."

"Are you alright, brother?" Aoki Tetsu, with an innocent look on his face, held up an electric fan. The hissing wind inside didn't blow towards him, but towards Aoki Makoto.

As an artificial human, even though he was despised as an inferior product by the Thousand World Trees, he had an extraordinary talent in terms of cold and heat resistance. Under the scorching sun overhead, Aoki Tetsu's face was not covered in sweat, and he still had the strength to take care of his useless older brother.

"Ah! This heartless world," Aoki Makoto wiped the sweat from his face, "Where did you go, Taigong Wang, you fisherman! Quickly give me a cooling buff! I shouldn't have participated in this team building activity!"

Looking left and right, all he saw were couples who, despite the sweltering summer heat, were still radiating the heat of their love. Aoki Makoto became even more indignant. What was going on? Did he come here just to watch these dog lovers show off their affection?

Makoto Aoki couldn't help but look at his younger brother, Tetsu Aoki, with satisfaction. His younger brother was the best; at least the two of them, being single, could comfort each other, so he wouldn't be all alone.

On the other hand, Makoto Aoki began to worry. His younger brother's romantic experience was practically nonexistent. His original official pairing with Jeanne d'Arc was impossible, and Astolfo had run off with Hachiman Hikigaya. What was he going to do now?

"Che-kun!" Duer, also an android, waved to Aoki Che. Since there were two "Aoki-kun" present, everyone called him by his name directly. "Could you help with the ingredients and barbecue grill we'll be using later?"

Just as Aoki Tetsu was about to agree, he remembered that his older brother was beside him, so he looked to Aoki Makoto for help.

Makoto Aoki looked at Duer, then at Tetsu Aoki, his feelings a mix of emotions, but he finally nodded: "Go help."

"Okay, brother." Aoki Tetsu obediently went to help.

Makoto Aoki watched Aoki Tetsu's retreating figure, then finally slumped back in his recliner as if giving up. Goodbye, this world where he's the only one who's single!

"By the way, where's Taiko-Wang, that single dog?" Aoki Makoto suddenly perked up.

……

"Hmm, summer is just so wonderful!"

On the other side, Hachiman Hikigaya, also a man, had a completely different idea from Makoto Aoki. At this moment, he was standing at the door of the changing room, gazing at the distant horizon, feeling incredibly happy.

This is the decisive moment! Hachiman Hikigaya was absolutely certain that there was only one reason why he would abandon staying at home and come out to brave the scorching sun!

That's Astolfo's swimsuit!

"Sorry to keep you waiting, Hachiman!"

A spirited voice came from behind.

Hachiman Hikigaya turned around with a smile: "Finally done..."

The dead-fish-eyed high school boy couldn't help but take a step back and subconsciously covered his nose. Fortunately, he wasn't so embarrassed as to have a nosebleed!

However, the scenery in front of us is truly exceptionally beautiful!

A light purple swimsuit hugged her slender body, revealing her delicate waist. Her lower body was covered by a skirt with ruffles, her fair and long legs, and her tender white feet with pink toenails on the soft sand.

Astolfo, completely oblivious to social boundaries, excitedly ran over and hugged Hachiman Hikigaya's arm, beaming, "Hey, let's go swimming together, Hachiman!"

“Okay…” Hachiman Hikigaya completely lost his usual rationality and followed along in a daze.

Beauty is misleading!

"I can't actually swim!" Someone's scream was drowned out by the splashing water.

……

"Eh—Arthur can't even properly enjoy the summer." Eriri drawled, sounding very regretful. If she had a cowlick on her head, it would definitely droop down.

Arthur smiled apologetically: "After all, the Lady of the Lake's blessing allows me to fight on the water, but it also prevents me from swimming freely in it."

The Lady of the Lake's blessing allowed Arthur to fight on the water as if it were flat ground, but just like the female Artoria, he could not go into the water.

"Eri is looking forward to it, isn't she?" The blond, blue-eyed young man looked at the girl with an indulgent gaze. "Have a good time. You've worked hard these past few days."

He touched the top of the blonde girl's head.

The young man in front of me was so handsome. Unlike his usual neat clothes with his collar closed, he was wearing tight black swim trunks with some gray patterns on them, and the hem of the trunks reached about knee-length.

His upper body was covered only by a white hooded jacket, the zipper undone, revealing his bare chest, his muscles perfectly undulating like mountains, exuding the power and heat of a crimson dragon with every breath.

A silver metal chain adorned her neck, and a cross dangled from her chest, drawing the eye and revealing the stunning view of her chest.

Under the blazing sun, the young man seemed to be completely absorbed into the light.

Eriri blushed and awkwardly turned her head away: "That's not true."

"And!" Eriri suddenly hugged Arthur's arm. The strength and warmth in his strong embrace made her blush. She said with dissatisfaction, "If I'm the only one here, there's no point in coming here!"

"Whether we play in the water or not doesn't matter, as long as Arthur is here!" Eriri announced loudly, her ears turning bright red afterward.

Arthur paused, then gently stroked her blonde hair: "But that would be rather boring."

Just as Eriri was about to shake her head and say, "With Arthur around, it's never boring," a volleyball suddenly came hurtling towards them with a whoosh. Arthur's eyes narrowed, and he spread his fingers, easily blocking the spinning volleyball.

"Want to play beach volleyball together?"

Charlemagne was dressed in an outfit very similar to that of King Arthur, as if he had just emerged from the water. Water droplets clung to his short, black and silver hair, disappearing into the black fabric along his neck and chest. His azure eyes echoed the sea, but his smile was as radiant as the sun.

"Your Majesty King Arthur."

His eyes were sincere and beautiful; anyone could see that he had no ulterior motives and had only come to help him out of a predicament.

Arthur chuckled: "Of course, Your Excellency Charlemagne."

"I'm off then, Eriri." Arthur's eyes crinkled into a smile. "Want to come cheer me on?"

"Of course!" Eriri clenched her fists, full of interest, not to mention she knew very well who the enemy was.

Sure enough, I spotted that familiar figure by the beach volleyball court.

One glance was enough to inflict a devastating blow on Eriri.

"Oh, isn't this Sawamura-kun?" Kasumigaoka Utaha, who was particularly hateful in Eriri's eyes, smiled slightly. "I really didn't expect you to come too."

She sighed softly: "After all, your weaknesses are too obvious, elementary school student."

Eriri almost vomited blood after being stung by the word "elementary school student".

Compared to Kasumigaoka Utaha, who has a curvaceous figure and a pair of large breasts that are almost bursting out, Eriri's flat-chested figure is indeed no different from that of an elementary school student.

Moreover, Kasumigaoka Utaha was boldly wearing a bikini, with a few pieces of black fabric covering her vital areas. She stretched slightly, and her erection almost popped out, making one's blood boil just by looking at it.

On the other hand, Eriri can only make up for her lack of cuteness with her sexy look, but the pink ruffles and the two-piece, conventional swimsuit make her look more like a child.

"That despicable Kasumigaoka Utaha!" Eriri almost ground her teeth to powder. "How dare she come out in a swimsuit like that! She has no shame!"

"There's nothing I can do about it," Kasumigaoka Utaha said with a hint of mockery in her eyes. "If you have a good figure, you have to let people see it, right?"

Eriri's face turned green. Damn it, this is too enviable. However, she has the same flat chest as her mother, Sayuri Sawamura. With her mother's bust size, she'll always be like this.

Fortunately, the war between the two soon came to an end, because... the final battle between Charlemagne and Arthur at the pinnacle of beach volleyball had begun.

"Take this!" Charlemagne leaped into the air, a bright smile on his face, his body soaring, his azure eyes reflecting the sky. With a powerful spike, he sent the small volleyball hurtling towards the opposite court with the sound of thunder and lightning.

While remaining calm, Arthur moved with exceptional agility, easily catching and returning Charlemagne's deadly attack with the powerful force born from the Crimson Dragon's heart.

The two players went back and forth, and the poor volleyball bore a weight it shouldn't have had to carry.

"Go for it, Arthur!"

Eriri, watching from the side, was filled with excitement: "You can definitely win!"

Arthur chuckled and said softly, "Okay."

Kasumigaoka Utaha wasn't about to be outdone: "Charlemagne, go for it! Don't lose!"

Charlemagne's thumb brushed against his cheek, the young man exuding confidence: "Of course, I'll win gracefully!"

The heated "battle" between the two kings attracted a lot of attention, and before we knew it, it had turned into a battle between the Knights of Arthur and the Knights of Charlemagne.

King Arthur & Bedivere & Gawain vs Charlemagne & Roland & Astolfo.

Gradually, what was originally just a game turned into a serious affair for both sides. After all, this clear-cut stance was like a clash between the King of Britain and the King of the Franks, and neither side could afford to lose!

“My king, let me lead the army for you!” Bedivere bowed his head loyally.

“My King!” Gawain retorted defiantly, “Under the sun’s protection, I will surely bring you victory!” Gawain was no joke when it came to the sun’s power being three times greater!

Arthur gently raised his hand: "It's been a long time, Lord Bedivere, Lord Gawain."

Let's fight side by side again!

Compared to King Arthur's unwavering loyalty and determination, Charlemagne's side was in complete chaos. Charlemagne looked at the two men beside him with a mixture of disbelief and strong suspicion that they were spies sent by the enemy.

"The sun is so bright!" Astolfo fanned himself with his hand. "Could I not join, Your Majesty?"

“The sun will burn my skin!” Astolfo declared confidently.

Charlemagne slapped him on the forehead: "You're a Heroic Spirit now, how could you possibly get sunburned, you idiot!"

"Right!" Astolfo finally realized, sticking out his tongue sheepishly.

Compared to the somewhat slacking Astolfo, Roland seemed quite enthusiastic, though his lines...

"This is so exciting! I really should take some clothes off, just one!" Realizing his king's horrified glance back, Roland quickly emphasized.

"Don't take it off! If you take it off again, you won't have anything left!" Charlemagne's voice was almost distorted. What do you mean, just one piece?! You only have one pair of swim trunks on, don't you? What's the difference between taking off one piece and taking it all off!

"Don't make us look like freaks!"

Charlemagne, the Frankish King and Father of Europe, was on the verge of a mental breakdown.

Why are the king's subordinates like that?! And why are they all so unreliable?! One is a cross-dresser, the other a streaking maniac—why can't they have someone reliable?!

Little did they know that the Knights of the Round Table were just as unreliable as Charlemagne, but what could they do when the two who were relatively reliable were the ones who came this time?

Charlemagne: I'm clearly the lucky one!

As for the outcome of this unprecedented battle... just look at the pile of beach volleyballs that were smashed to pieces.

……

"If we're coming to the beach, we definitely have to go sea fishing!" Cú Chulainn said happily, holding his fishing rod. "I'm really good at fishing!"

"Really..." Hiratsuka Shizuka was a little doubtful.

"Want to go fishing? Count me in!" An unknown person passing by excitedly expressed his desire to join in.

“Great!” Cú Chulainn was delighted to have a fellow angler join him. “If you’re having trouble catching anything, you can ask me for advice!”

An hour passed.

Two hours passed.

Cú Chulainn gained nothing!

Cú Chulainn remained calm and composed despite being surrounded by swords, his face even more excited than before, though it was slightly stiff.

"Oh dear, it's biting again." The oldest fisherman sitting next to me smiled as he cast his line. The transparent fishing line pulled up a large yellow croaker weighing a full ten pounds. Even though the fat fish struggled fiercely, the strength of the spirit was not to be underestimated, even though this guy's panel was filled with a C.

He easily removed the large yellow croaker from the hook, but Taigong Wang had a headache: "Oh dear, there's not enough room in the boat."

Behind him, a mountain of fish had been piled up, including sea bass, large yellow croaker, eel, and even tuna over a meter long—all his spoils from the past two hours.

In comparison, Cú Chulainn, who gained nothing, appeared extremely embarrassed.

Hiratsuka Shizuka, watching from the side, mocked her servant without any courtesy, saying, "Want me to try instead?"

Cú Chulainn gritted his teeth: "No need!"

He quietly moved to another spot, far away from Taigongwang, and continued fishing. This guy must have sucked away his luck! He's clearly not an E-rank lucky person!

He refused to believe it; he was sure he could catch a fish!
