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

"Hey, Saburo-sama." Nakano Miku's cheeks were flushed, and she didn't dare to look at anyone, instead staring at her tangled fingers.

Are you free next Wednesday?

"Next Wednesday?" Taking a rare day off, Oda Nobunaga wasn't wearing his crisp military uniform, but rather a white T-shirt and his blood-red cloak. He thought for a moment while playing a game. "It shouldn't be. Is there something you need?"

Oda Nobunaga retorted with a question.

“Um,” Nakano Miku took a deep breath and was finally able to say it smoothly, “Next Wednesday is the fireworks festival and the five of us sisters would like to invite you to go with us to thank you for saving us in the first place!”

He spoke a string of words without pausing.

"Fireworks festival?"

Oda Nobunaga tossed the game console aside and rested his chin on his hand.

"Hmm, it looks like it's going to be very lively, how could it be complete without you!"

"Okay, let's go together!"

"Great! I'm definitely going to dress up nicely then." Nakano Nino was incredibly excited and was already thinking about what to wear.

"Yes, it's rare for us to act together." Nakano Ichika smiled slightly.

"Hehe! I knew Lord Nobunaga was easy to talk to!" Nakano Yotsuba's ribbon on her head trembled.

"That's true, but we still shouldn't let our guard down too much!" Nakano Satsuki pushed up her glasses. "Anyway, let's get the yukata ready first."

"Speaking of which, does Master Shin have a yukata?" Nakano Nino noticed the blind spot.

“Indeed, I’ve only ever seen Lord Nobunaga in military uniform, never in traditional clothing.” Nakano Ichika tapped her cheek.

"You mean kimonos?" Oda Nobunaga started another game. "I'm tired of wearing those. I prefer Western things. Besides, it would look weird to wear one in modern times."

“Actually, military uniforms are also…” Nakano Yotsuba blurted out, but thankfully Itsuki next to her covered her mouth.

Nakano Satsuki wiped her sweat. She really worried herself sick over this family. Even though she was the younger sister, she had to worry about her older sister.

"Yukata? You can prepare those yourself." Oda Nobunaga waved his hand, not caring much about it. "Anyway, whatever I wear, I'll definitely be the most dazzling one!"

"So, you mean we're going to prepare a yukata for Shin-sama?" Nakano Nino's eyes lit up, and it seemed like pink bubbles were rising from behind her.

Preparing a yukata for Lord Shin is just like being a wife, isn't it?

"boom--"

Nakano Miku slapped Nino's cheek, her eyes flashing coldly: "You can't take it from me, Nino."

"what the hell."

Nino Nakano stood her ground, arms crossed, chest puffed out and head held high: "At times like these, it's best to rely on your own abilities, Miku."

Their eyes clashed, and lightning flashed and thunder roared around them.

……

"Hey, Hachiman, do you think this outfit looks good?"

Astolfo wore a light purple yukata adorned with cherry blossom patterns, and a blue obi tied at the back with a large bow.

Astolfo excitedly opened his arms and spun around: "Isn't it beautiful? Isn't it beautiful?"

"Beautiful!" Hachiman Hikigaya nodded repeatedly.

"Huh? This one looks good too..." Astolfo was torn between the various yukatas on the sofa. "Which one should I wear?"

“Hey,” Hiratsuka Shizuka scratched her head, “aren’t you guys a little… have you forgotten that Astolfo is a boy? Why are even the yukatas women’s styles?”

Shizuka Hiratsuka truly believes that Hachiman Hikigaya is finished.

"What are you talking about, Hiratsuka-sensei?" Hachiman Hikigaya looked at Shizuka Hiratsuka with clear yet foolish eyes. "Isn't the point of the fireworks festival to see Asuka's cute yukata?" Just like the only expectation for going on a school trip is to soak in a hot spring with Saika. Of course, at the moment, Hachiman's heart is set on Asuka!

What else could there be! Hachiman Hikigaya has absolutely no interest in fireworks, a game that's only for people with a normal life—even though he's currently seen as such by others.

"Never mind, I'll leave you to your own devices. As long as you're happy." Hiratsuka Shizuka waved her hand. In any case, she was a very open-minded teacher and wouldn't interfere too much in her students' romantic relationships.

What's more, her own love life is a complete mess.

“Speaking of which, teacher,” Hachiman Hikigaya squinted, “I feel like I’ve been seeing you a lot lately. This is my house, isn’t it?”

Of course, this is his new home. His previous home was in a residential area, where he was easily surrounded by onlookers... After all, he won the Holy Grail War, and this detached villa was a reward from the Japanese government to Hachiman Hikigaya.

There weren't many people around, which made it a good opportunity for Scáthach and Cú Chulainn to spar frequently.

Usually, only his father and younger sister, Komachi, would come.

Hiratsuka Shizuka choked back a sob: "Well..."

The black-haired female teacher's eyes darted around: "After all, it's not convenient for me to go back, and Cú Chulainn keeps coming to see Scáthach!"

As she continued, Hiratsuka Shizuka spoke with self-righteousness.

To be honest, she didn't want to face the mocking gazes of those familiar people at all, and she even temporarily stopped going to school. Of course, the school couldn't possibly expel their female teacher who had summoned a heroic spirit.

Of all the people I know, this place is a bit quieter than Qigu.

“Well, I actually wish Cú Chulainn would come too.” Hachiman Hikigaya sighed softly. “As long as Cú Chulainn is here, Scáthach-sensei won’t keep me training.”

Of course, the training plan still needs to be completed, but without Scáthach personally sparring with him, it's basically just beating him up.

So, thanks to Cú Chulainn for attracting Scáthach's attention, it's better to die for a friend than for myself!

Hiratsuka Shizuka rolled her eyes at him.

Hachiman Hikigaya shook his head. He was still single at his age, which was definitely related to Shizuka Hiratsuka's overly carefree attitude.

"Aren't you planning to go with him?" Hachiman Hikigaya asked.

Hiratsuka Shizuka turned her head away: "I'm past that age. Fireworks festivals are for kids."

Hachiman Hikigaya didn't believe a word of it: "But it's okay to go, right? Get your yukata ready, I'll go talk to Cú Chulainn."

"Hey!" Hiratsuka Shizuka almost jumped up. "Don't make decisions on your own!"

"Teacher." Hachiman Hikigaya sighed softly, his eyes filled with seriousness, as he spoke of a truth he had only come to understand after experiencing the Holy Grail War.

"No matter the outcome, at least don't let yourself have any regrets."

How regrettable it would be if, many years later, I regretted not having the courage to take that step back then.

When Hiratsuka Shizuka faced Hikigaya like this, she felt like she was the student.

She shrank back and whispered, "I know."

Hiratsuka Shizuka looked at herself and fell into deep thought. Should she buy a new outfit? But would that seem too eager?

Hiratsuka Shizuka began to feel distressed.

……

In the dimly lit room, only the light from the computer illuminated the woman's blushing eyes.

Having finally learned how to use a computer, Kaguya Shinomiya scrolled through the information on it.

Her gaze lingered on a passage on the screen.

"

Fireworks are the essence of summer, and one should watch a fireworks display with their loved one at least once in their life to ensure their youth is without regrets.

Love, my lover?

Kaguya Shinomiya covered her burning cheeks; she... she...
