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

Like the sound of locusts flapping their wings, hundreds of thousands of Barrahmu formed a dark cloud and rushed toward the island at an extremely fast speed. Heroic spirits with clairvoyance could even see the Barrahmu's excited movements.

They crave to kill humans; their very existence is for the purpose of slaughtering humanity.

Beneath the surface, countless Rahms were swimming towards them, enjoying themselves immensely as children of Tiamat.

"Prepare!"

Hector was also in command during the battle. His brown eyes gleamed with a shrewdness, and he was a true veteran of the battlefield. Compared to him, Joan of Arc was more of a morale-boosting figure.

"put!"

Once Lahem was closer, Hector immediately gave the order.

No sooner had the words left his mouth than the Heroic Spirit, who had been preparing for a long time, unleashed his Noble Phantasm.

"Namo Hachiman Daibosatsu. If my wish is fulfilled, may this arrow strike its mark! Hachiman's Prayer - Great Demon Piercing Arrow"

(なむはちまんだいぼさつ?このやにかごを)! ! "

"Raging Moon Converges - Shape Change. Moon Chant Rotation Cannon, Boom Sink - Bow Moon (Gouchin Yumiharizuki) Countdown Begins, Three, Two, One... Launch!"

"■■!! (The Five Weapons of the God of War)!!"

"Hehe... Severed by treacherous schemes, the right arm, lost and then regained, has transformed into a monster! Gallop, Murakahara! The great grudge of Rashomon arises!!"

"Let me take you to the Land of Shadows, Gae Bolg Alternative!"

……

The Heroic Spirits with ranged attacks unleashed their Noble Phantasms. Among them, Minamoto no Tameaki's "Bow and Moon" had an added bonus at sea. Of course, the most eye-catching was Lu Bu, who resembled a demon god, whose violent power blasted a hole in the air.

The front row of Rahmu was almost completely cleared out, which made the sky a little brighter, but the Rahmu behind were still arriving in droves.

"Forwards, prepare!!" Hector gave the order, and all the relevant Heroic Spirits sprang into action. They were all high-speed Heroic Spirits who could escape at any time.

“I’ll leave the rest to you, Achilles.” Hector and Achilles looked at each other, exchanging glances. As mortal enemies, they trusted each other implicitly.

"Don't worry!" Achilles laughed arrogantly. "These scum without divinity, watch me slaughter them seven times in and seven times out!"

Hector, who was almost killed by "scum without divinity": feels like he's being subtly insulted.

However, Hector couldn't help but laugh. As an ally, Achilles was a very reassuring figure.

"Get me excited, let's run!"

Holding the reins, Achilles let out an excited roar.

“Achilles, are you in a good mood this time?” Xanthos snorted and teased.

"Ah, after all, it was Hector's request." Achilles made no attempt to hide his surging fighting spirit as he rode the battlefield, unleashing his Noble Phantasm.

"Xanthos! Balius! Pedasos! Charge! Charge with your lives on the line! My life is like a shooting star! The undead chariot of the raging storm! (Troias Tragoidia)!!"

The chariot transformed into a green meteor, ravaging the battlefield with incredible speed. This Noble Phantasm increases the percentage of damage dealt as speed increases. At its top speed, it was like a giant, running lawnmower, turning any Lahm that it grazed into mincemeat.

Achilles, just as he had said, easily slaughtered the Lakhm horde. The Lakhm could not harm him, and the Lakhm corpses falling from the sky were like a terrifying black rain.

However, the number of Heroic Spirits was limited, and the Rahms were by no means mere grunts, not to mention their sheer numbers were overwhelming. Soon, it was time for close combat.

At this point, Servants with defensive Noble Phantasms do have a certain advantage.

Chacha stood on the city wall, protected by the fortress's treasures, and Rahmu couldn't break through for the time being.

She proudly put her hands on her hips: "Let Uncle see Chacha's true abilities! Come out, Sanada Yukimura, Goda Mototsugu, Mori Katsunaga, Chosokabe Morichika, Akashi Takenori, fight for me!"

These famous daimyo and warlords from Japanese history were summoned as skeleton soldiers, who roared and attacked Lahem.

Even without their Noble Phantasms, or even in the form of skeleton soldiers, their honed martial arts skills make them formidable opponents.

"Hahaha, a mere Rahm is nothing!" Chacha always gets carried away when she's feeling triumphant.

Then, a Rahm crashed into the burning Osaka Castle, and the entire fortress trembled.

"Huh?" Cha Cha was startled.

Then, finding nothing amiss, she patted her chest and said, "Thank goodness, I'm alright..."

Before she could finish speaking, one Rahm after another rushed towards her.

Chacha's face turned deathly pale; she wasn't a Heroic Spirit skilled in combat at all: "What am I going to do?!!"

Fortunately, Tomoe Gozen and Beowulf, who were guarding Chacha's Noble Phantasm, quickly dealt with the attacking Rahm.

However, immediately afterward, another wave of Rahms formed and pressed in.
