Heroic Spirit Deck in Yu-Gi-Oh!

"Hehe, now I have all 5-star servants. Even though it cost me a lot, and the last servant was particularly hard to get, costing me seven more singles," the girl laughed foolishly at her phone screen as if she were possessed.

"My dear Artoria, you are so beautiful." The screen displayed the popular mobile game FGO, and Hoshino Chiyuki couldn't stop poking Artoria in My Room, her face full of adoration.

Her darkroom was plastered with various anime posters, ranging from hot-blooded guys to sexy characters. The shelves were filled with exquisite figurines, each displaying the perfect bodies that real-life men and women could hardly possess. It was a typical otaku girl's room, and it looked like she had a wealthy family.

Hoshino Chiyuki, an ordinary high school girl, came from a rich family. She had a slender figure and a cute and pure appearance. However, since her second year of high school, she had become addicted to 2D- world and couldn't stop. Eventually, she evolved (or regressed?) into a shut-in otaku, spending all her time on anime and mobile games. By the second semester of her second year, she even refused to go to school.

Her doting father, who had spoiled her since she was little, was at his wit's end. Her mother had passed away when she was very young, so she had no memory of her. As a business magnate, her father treated her like a treasure. So, even when he saw her become obsessed with the 2D world and unwilling to go to school, her doting father just let her be.

Satisfied, Chiyuki exited My Room and opened her Spirit Collection, slowly scrolling from top to bottom. It was a complete collection, not a single one missing, revealing how much time and money she had invested in FGO.

"Sigh~" She sighed softly, reminiscing about her servant, and then looked around her dim room. For some reason, a faint sense of loneliness crept into her heart.

"Just through a screen, it feels so empty. If only they were real~" Perhaps tired of her monotonous life, Chiaki silently fantasized.

"——Duel System activated, Duel Code 001, Name: Hoshino Chiaki, login complete."

"Huh? What's going on? Who's speaking?" Chiyuki felt a strange voice suddenly echoing in her mind, saying inexplicable things.

"Creating Duel Deck, converting Spirit Deck~"

"Ah! Ah! What's happening?" Chiyuki frantically watched her phone, witnessing what seemed like the most horrifying scene of her life.

She watched in disbelief as her Spirit Collection dimmed and disappeared one by one. (TL: DATA LOST?)

"My Husbando, my wives, my money! No!" For Chiyuki, this was one of the most unacceptable disasters of her life.

But Chiyuki's heart-wrenching cries couldn't stop this bizarre phenomenon. One by one, Artoria, Emiya, Gilgamesh, Merlin, Waver, Tamamo, and Okita…all vanished!

"Mash, even Mash is gone, waaaah." Finally, Chiyuki's once-proud complete Spirit Collection was entirely gone.

"It's over, everything's over. I have no will to live in this world anymore." With a face like death, Chiyuki dropped her phone, her slender body collapsing into the chair.

"——Heroic Spirit Deck creation complete, transitioning to Duel World."

Chiyuki, whose mood had plummeted, instinctively ignored the voice in her mind.

But the surrounding scenery forced Chiyuki to pay attention.

"Huh? What's going on?" The scene around her shifted and blurred unpredictably, causing Chiyuki to panic.

Leaving her chair, Chiyuki tried to find a way out. But at that moment, her familiar room seemed infinitely enlarged. No matter how she ran, it felt like running on a treadmill, unable to find an exit.

After a few minutes, the blurry surroundings gradually cleared up. However, the scene that emerged was no longer her familiar room.

A slightly salty breeze ruffled Chiyuki's hair, making her fair face itch.

"Sea breeze?" Although Chiyuki often stayed indoors, she knew enough to recognize the sudden sea breeze, which puzzled her.

"I was clearly in my room. How could there be sea breeze?" Chiyuki turned her clear eyes to observe her surroundings.

Luxurious, splendid, resplendent—these words barely did justice to her current environment. She was on a luxurious passenger ship, sailing on an endless dark sea.

"Where am I? Am I dreaming?" Chiyuki, having taken in her surroundings, felt even more confused.

"System prompt: Currently aboard the ship heading to the Duelist Kingdom." An emotionless, mechanical voice echoed in Chiyuki's mind again.

"System? Duelist Kingdom?" The familiar yet strange names jogged Chiyuki's memory, and she felt the answer was on the tip of her tongue but couldn't quite say it.

"Man overboard! Help!" The previously calm ship suddenly became chaotic as passengers shouted for security.

Interrupted from her thoughts, Chiyuki decided to join the crowd to see what was happening and perhaps find some clues.

"Jonouchi!" At the edge of the ship, a spiky-haired boy shouted into the dark sea.

After a few minutes of rescue by the security team, the young man named Jonouchi was finally pulled from the water.

"Sorry, Yugi. I only managed to retrieve two Exodia. The other two were washed away by the waves." The blond youth, Jonouchi, looked apologetically at the spiky-haired boy.

The spiky-haired boy firmly grasped Jonouchi's hand, looking relieved, "It's okay, Jonouchi. As long as you're safe."

Such a cliché and corny display of friendship, yet the surrounding spectators were moved to tears.

Chiyuki, on the other hand, didn't comment on the cliché plot; she stood there, dumbfounded.

"Jonouchi? Yugi?" Chiyuki murmured to herself.

"Yugi? Yugi Mutou! Your full name is Yugi Mutou, right?" Like a bolt of lightning, Chiyuki rushed forward and urgently asked the spiky-haired boy.

Yugi, startled by the sudden approach, stammered, "Yes, that's right. I'm Yugi Mutou."

Jonouchi glanced at Chiyuki, then jealously grabbed Yugi's shoulder and whispered, "I envy you, Yugi. After defeating Seto Kaiba, you've become famous, and now you even have a cute girl fan."

Listening to Jonouchi's whisper, Yugi awkwardly smiled.

"Yugi Mutou, Jonouchi, Duelist Kingdom! I get it!" As Chiyuki's thoughts cleared, childhood memories slowly resurfaced. Though she hadn't watched much of the anime, as an otaku, she still recognized these iconic characters.

"The world of Yu-Gi-Oh!" Chiyuki exclaimed in her heart, "Oh my God, I transmigrated into an anime world."

"But why Yu-Gi-Oh!? Before I transmigrated, I was thinking about my Servant waifu. It should have been FATE world."

"Ow!" Feeling something poke her thigh, Chiyuki instinctively reached into her pocket.

Sure enough, it was a standard Yu-Gi-Oh! card back. Chiyuki pulled out a mysterious deck from her pocket. She swallowed nervously and flipped over the first card.
