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

Kaito Kuroba never expected that his skill and daring, along with his servants, would lead to such a thrilling scene after just a short trip to an island outside the front line of defense.

"Hey, this is too exaggerated."

Kaito Kuroba saw the group of Rahms through the binoculars and looked pale. Luckily, they were Rahms and not fish, otherwise he would have run away by now.

After all, everyone knows that Kaito Kid's lifelong nemesis is Makoto Kyogoku and Uo.

"This proves you really are an unlucky guy, Master." A charming and seductive voice came from beside him.

Kaito Kuroba, unfazed, retorted, "Who said that? I'm loved by everyone!"

Need I say more about Kidd's popularity?

"Hehe, handsome masters are very popular, so even monsters love them."

"That won't be necessary," Kaito Kuroba said helplessly. "Why are all you witches the same?

They all have such a twisted sense of humor!!

Unlike other witches who would disguise themselves as non-human, Circe appeared in her true form, with her azure eagle wings spread out, eagle feathers adorning her head, and long ears below. She was petite, with a delicate and lovely appearance. What was most captivating were her strange eyes, pink on top and green on the bottom. It was a pity that her beautiful hair, which even Homer admired, had been cut short, only reaching below her ears.

She exudes an inhuman aura, yet she is like a myth or epic finally coming to life, carrying an incredible dreamlike quality, unlike any being in the mortal world.

This is Circe, the Eagle Witch of the Age of Gods.

She was also a Servant summoned by Kaito Kuroba. Although he never understood why he summoned Circe, shouldn't Koizumi Akako be more suitable in terms of compatibility?

"Is this quantity really okay?" Kaito Kuroba was filled with worry, but he quickly calmed down. "Caster, I will use Command Seals to support you if necessary."

"Please! There are other Heroic Spirits too. You must stop these monsters, otherwise the others..." Kaito Kuroba's mood plummeted as he thought of the horrific incident he had seen on the news. In the end, Kaito Kid wasn't exactly a vicious criminal, so the Japanese police still had reservations about him.

“Although you enjoy doing petty theft, Master, you’re still a good person at heart,” Circe teased.

"What do you mean by petty theft!" Kaito Kuroba wouldn't allow his profession to be insulted, and retorted in a low voice, "That's a phantom thief, a phantom thief! I would never do anything so low-class. I returned all those gems to them in the end."

All he was looking for was Pandora.

"Alright, alright," Circe said with a grin. "I know, I don't hate Master, otherwise I would have turned you into a pig and hung you in the freezer long ago."

"Haven't you done it before?!?!" Kaito Kuroba exclaimed indignantly. This was practically the darkest chapter in his life, and Terai still couldn't help but laugh when he saw it.

“Because even a witch is still a girl, and anyone who dares to step on her landmine must be punished.” Circe’s pink-green eyes narrowed dangerously. “Or does Master have a problem with that?”

“…No, I wouldn’t dare.” Kaito Kuroba was extremely frustrated.

However, he has also reflected on his actions. He did indeed touch Circe's sore spot with his words, and thus he was tragically turned into a pig.

"Alright, Master."

Circe's voice turned serious: "I've already notified the others, but it will take some time for reinforcements to arrive."

"You'll stay in the area I just set up. You can use your enchanted weapons, but—"

"Be prepared, I'm not very good at dealing with this type of enemy."

Circe looked somewhat downcast. She was indeed one of the most powerful witches in mythology, but as legend has it, she was more skilled in shapeshifting and poison.

"Ah, I believe you, Circe."

Kaito Kuroba revealed a confident smile: "Please believe me, Phantom Thief Kid won't fall here so easily."

Kaito Kuroba declared that his luck couldn't possibly be that bad!!

"Moreover," the black-haired boy said with a determined look in his eyes, "this is not just your battle, it's our battle too. Don't underestimate humans."

Circe couldn't help but laugh: "Alright, Master, I'll wait and see."

After saying that, Circe's eyes sharpened as he stared at Rahm in the distance and sneered.

"Hehe, let's build a pigsty here."

With a flap of its wings, Circe took flight in the air.

As the Witch of the Eagle, even without related legends, the sky is Circe's domain.

A pink magic circle unfolded in front of the wand, and pink lightning formed a chain that sealed off Rahm at the front.

The front row of Lahms involuntarily twitched and fell to the ground, but the Lahms behind them did not hesitate and stepped over their own kind to continue forward.

One of the Rahm even chuckled a few times, then suddenly leaped up, using all its strength to jump over her, though it didn't actually reach Circe.

"Ugly creature, take this!" Circe yelled in annoyance, waving her wand. "Magic... Unleash."

With his high-speed divine speech, Circe can activate magic without using incantations or connecting magic circuits, and can activate great magic in the time it takes to complete a single action.

This ability is among the best of all magicians.

Just now, simple syllables stirred up a magical hurricane, sweeping away the first few Rahms that were approaching the island.

Very tricky.

Circe is considered one of the most powerful witches in mythology, but unfortunately, she is better at cursing and poisoning. In terms of pure combat strength, she is not good at dealing with such a large number of fierce enemies.

Her most prized ability, the Pig Transformation Technique, is not something she can use casually. It usually requires the enemy to eat food, which means it needs to be used in conjunction with a Noble Phantasm. Simply using the Pig Transformation Technique is unlikely to be effective against a monster like Rahm.

As for poison, she cannot use it for the time being. If the poison spreads to the Master, it will be disastrous. Even if the defenses are strong, they won't hold for long, and Kaito Kuroba will die.

Kaito Kuroba was currently staying obediently in the makeshift position built by Circe. Although he had boasted earlier that he was fearless, he was still very self-aware. He was a phantom thief, not a brute. Why would he go and fight a monster head-on?

Therefore, he carefully concealed his presence, because he knew of Rahm's malice towards humans. There had been previous cases where Rahm would even prioritize attacking humans over Heroic Spirits.

Not wanting to cause any trouble for Circe, Kaito Kuroba focused intently.

Wait! The exceptionally perceptive thief spotted a blind spot. Was that blade of grass on the ground just now flattened?

Oops!

Kaito Kuroba rolled away and quickly moved away from that place.

"Chichichichi!!"

Under the constraints of the position, Rahm emerged from its invisible state. Among the numerous Rahm, there are always a few with special abilities. At this moment, its sharp scythe-like feet were blocked by an invisible barrier. It seems that even if Kuroba Kaito doesn't escape, he will be fine.

But Kaito Kid isn't one to sit idly by and wait to die!

During the roll, Kaito Kuroba quickly drew his enchanted pistol from his waist, stopped, and immediately knelt down to fire.

"grumble--"

Rahm let out a sharp scream, and dark red blood gushed from his hideous mouth.

As everyone knows, Phantom Thief Kid doesn't kill people, so his gun doesn't contain bullets, but playing cards.

However, when dealing with monsters, one naturally has to disregard martial ethics.

Rahm swung his limbs wildly, beginning to attack the defensive spells left by Circe.

Kaito Kuroba's hand was very steady. Almost all the bullets in his magazine hit Rahm's mouth. If it weren't for the monster's strong vitality and endless malice towards humans, he would have won long ago.

His heart was pounding like a drum, but the more nervous he became, the calmer he remained, befitting a magician's mindset.

He can win!

Remembering Circe's instructions to him, Kaito Kuroba had a sudden inspiration.

Circe, of course, noticed the predicament on Kaito Kuroba's side, and she was so angry that her eyebrows furrowed.

You've made me angry!

The Eagle Witch's voice was chilling. A golden goblet appeared in her hand, filled with a suspiciously bubbling purple liquid—her carefully brewed poison: "Want to taste it, you ugly creatures!"

Circe possesses the A-rank "Poisonous Delicacies," and in terms of poison, she surpasses Semiramis's "The Arrogant King's Wine." If it weren't for her concern for her fragile Master, she would have poisoned him long ago.

As for now, a cold glint flashed in Circe's eyes. It would take some time for the poison to spread to Kaito Kuroba, and she would take this opportunity to move her Master away.

Of course, she remembered setting up another barrier behind her to slow the spread of the poison to the island.

She poured out the poisoned wine from the golden cup, which appeared to be miniature, but contained an endless supply of poison, covering most of the Rahm.

The Rahms who came into contact with the poisoned wine screamed, but their shells gradually softened and melted. Even the Rahms that were not covered staggered as if drunk, but after falling down, they stopped moving.

Within a radius of several miles, all living things perished, and this was the result of Circe intentionally controlling the area.

That's why she's not very willing to use it; on the battlefield, it's a typical case of not being able to distinguish friend from foe.

This is not over yet.

"Rise from the depths of the water!"

Circe chanted the incantation, and in the lake formed by the poisoned wine, the monster Scylla emerged from the wine with her head. She had six heads, twelve legs, and a cat's tail. Her ferocious head crushed a Lahm in one bite.

It's a bit embarrassing to admit, but Scylla was originally a beautiful sea nymph, the daughter of Phoebus, the god of the sea. The three Medusa sisters were also among her many brothers and sisters. It was Circe who poisoned her, turning her into such a terrifying monster.

Therefore, no matter how lovable she may seem, Circe is an extremely dangerous witch.

Just as Circe was about to return, she heard a whooshing sound behind her. She held her wand in front of her and blocked the scythe-like foot of a hidden Baallahhem that was about to strike.

The immense force sent Circe flying, and it took several flaps of its wings to regain its footing.

The sound of explosions came from afar, and Circe could no longer sense his own position.

What's wrong with Kaito Kuroba? Although he didn't feel the contract break or the other side of the contract lose any life, Circe was undoubtedly enraged.

"Damn it! Get out of my way—"

Several magic circles unfolded in front of the wand, and the terrifyingly powerful magic cannons scorched the air, burning the unprepared Balrahim to ashes.

Circe didn't dare to stop for a moment and quickly used magic to teleport back to his position on the island.

Then she was surprised to see that Kaito Kuroba had suffered a minor injury, while in the distance lay a dead Rahm with its skin torn open.

The stronghold she had built was already in disarray.

"You blew up my position?" Circe saw through Kaito Kuroba's actions at a glance.

“Yes, sorry, if he had destroyed all the spells, I wouldn’t have had a chance to fight back.” Kaito Kuroba chuckled. “So I just detonated the position you left behind, and luckily, I killed it.”

“This isn’t something that can be achieved by luck,” Circe chuckled. “Didn’t you think about what if there were still enemies?”

Kaito Kuroba answered seriously, "I've thought about it, but sitting idly by and waiting to die isn't my style. Let's take a gamble."

He was anxious until Circe arrived, but now he can finally relax.

"Kaito Kid has really good luck!" Kaito Kuroba gave a thumbs up.

After all, he hadn't messed up for so long before, and this time, he won his gamble.

Circe couldn't help but let the corners of his mouth curve upwards slightly.

“We have to leave immediately.” Circe could feel the poison spreading through his wine. “Otherwise, the sea breeze will soon carry the poison over. I’ll remove the poison once you’re gone.”

Otherwise, given Circe's poison skills, who knows how much of an impact it would have caused.

"But what about the defenses here?" Kaito Kuroba wasn't indecisive; he was just afraid that if they left, the defenses would be breached.

"Hehe, are you the people Lady Anzhen asked me to support?"

After the Heroic Spirit was released from its spirit form, a sweet and beautiful girl appeared before him. She was wearing a kimono and had a delicate and charming beauty. However, her white dragon horns and vertical pupils meant that she was not a pure human Heroic Spirit.

"Berserker, real name Kiyohime, hehe, I'm not very good at fighting."

Kiyohime held a black and gold folding fan, lightly covering her crimson lips.

"Now that reinforcements have arrived, I'll go deal with the poison bar first." Circe breathed a sigh of relief. "Please help protect my master." Although she said that, Circe still left many spells on Kaito Kuroba before flying away.

Only Kiyohime and Kaito Kuroba remained.

Kaito Kuroba tried to strike up a conversation: "Hello, I am Circe's Master..."

"I smell a lie!" The green-haired dragon girl narrowed her eyes dangerously. "You wouldn't happen to be some kind of big-time liar, would you?"

Kaito Kuroba, the phantom thief who lies without thinking, instinctively tensed up. He reflexively wanted to refute him, but Kiyohime whispered in his ear, "Please don't lie."

Kaito Kuroba felt a chill run down his spine, and he obediently replied, "I have indeed lied." Especially to Aoko, the number of times he had lied was countless.

"This is the truth!"

Kiyohime smiled and commented, "It's quite good that you can admit it so readily."

"I hate lies, and liars should be burned at the stake. What do you think?"

Kiyohime pressed closer and closer.

Ah... His answer of yes or no wouldn't work either. Kaito Kuroba was sweating profusely. He thought Circe, the witch, was already terrifying, but Kiyohime was the most terrifying of all. By her standards, he would definitely be burned to death.

Shouldn't we be glad that his servant is Circe and not Kiyohime?

"This is my Master! You've crossed the line, Kiyohime!" In a flash, Circe used spatial teleportation to instantly block Kaito Kuroba's path, looking at Kiyohime warily.

"Hmm, it's not my Lady Anchin. Honestly, why am I standing guard here?"

As expected of a berserker, Kiyohime's thought process is quite problematic.

"But since it was Lady Anchin's request, I have agreed and can only keep my promise. After all, honesty is the most beautiful thing in the world."

"Ah, you're a Caster, right?" Kiyohime suddenly asked Circe, squinting her eyes.

“That’s right.” Circe nodded, puzzled.

"It's supposedly some kind of order, telling all the casters to go to the rear and wait for orders," Kiyohime said with a smile. "Hurry back, I've already told you everything I was asked to convey."

"Is there something urgent?" Circe thought for a moment, then picked up Kaito Kuroba and flew off the ground.

"Hey! What are you doing?!" Kaito Kuroba protested loudly. This was too ugly! It ruined his handsome image!

"Enough talk! Ready? Let's go!"

Accompanied by a boy's scream, Circe flew away from the island at breakneck speed.

"Hehe, next up are you guys, please don't waste my time."

Kiyohime gently waved her folding fan, its flame patterns so dazzling, while in the distance, another small wave of Rahms swept across the sea.

"Ah...so sad...so sad...so sad."

Kiyohime looked sorrowful: "Is it you who forced me to leave Lady Anchin?"

Her expression turned incredibly angry, and the leaking magic transformed into flames that spread from her feet.

"Burn them all to death! Turn around and become a Samadhi of Fire (Tenshin Kasho Zanmaii)!!"

The raging flames, like an endless fire of hatred, burned on the sea for a full day and night before finally being extinguished.
