I became a girl group idol for my sister.

As she spoke, she glanced at the people around her.

"This is not only an important step for SKG to establish itself, but also a declaration of war by SKG against SKR. We have no regrets about being content with our position as the SKR sister group. We will strive to move forward. Everyone, this time we must work hard, even harder than usual! If we don't work hard, the people in Nagoya will not recognize us!"

"SKG!! Oh!!!"

They shouted loudly, and at that moment, everyone's morale reached its peak. With this surge of energy, everyone immediately sprang into action. Miyamoto and Nanase Touka went to the dressing room to change clothes and prepare for the rehearsal in a little while.

Renting this kind of venue is incredibly expensive, so we have to train as fast as we can.

No one wants to waste time at this time, especially for these girls who dream of becoming idols.

"But speaking of which, doesn't this mean that Nana-chan and Fuyu-chan are going to war against their own SKR?" someone suddenly muttered.

"That's right, but now Nana-chan and Fuyu-chan belong to SKG, so there's no problem!"

“That’s right, we belong to SKG now, so there’s no problem.” Miyamoto, who had already changed his clothes, said as he walked over: “Besides, declaring war on SKR’s seniors is a lot of fun, isn’t it?”

"Fun?"

"Yeah, it's fun, so fun it gets my blood pumping!" Miyamoto's eyes were full of excitement. "And the thought of standing on the stage of Nagoya Dome in front of so many people is already energizing me!"

Whether facing SKR as SKG or standing on the stage of Nagoya Dome as an idol, for Miyamoto Sei, a single reason was enough to make him give it his all, not to mention that he had both reasons at the same time.

This thrilled him!

Chapter Four: Nagoya Dome

2019 3 Month 6 Day.

Nagoya Dome venue.

The scene was packed with people, and all the tickets for more than 50,000 people were sold out, including all three days' worth of tickets.

Even though this was just a performance by one of SKG's sister groups, the fact that it received such an exaggerated response demonstrates the fans' love for SKG and these young idols.

"I took three days off just to see this show!"

"Three days? So you're going back to work this weekend?"

"No way! I want to spend two days this weekend reminiscing about the performance. I can leave work for next week!"

"I took the day off too, hahaha!"

"What's work compared to watching such a grand performance? Hahaha!"

"This is SKG's first large-scale independent performance, we have to support them!"

"I heard that Nana-chan and Fuyu-chan are back this time too! That's great, we can finally see them standing with everyone from SKG again!"

"If we're talking about SKR headquarters members who have performed at Nagoya Dome, Nana-chan and Fuyuka-chan would be the first, right?"

"Because they're members of SKG now! SKG's!"

"Even though they've finished their concurrent roles, they are still SKG members!"

"I came all the way from Tokyo! Oh my god, Nana-chan is on the Tokyo Dome stage again!"

"Finally, finally this day has come! The day SKG has its own dome performance! I'm so excited I could cry! It feels like my daughters, whom I've watched grow up all this time, have finally grown up!"

Yukari Kojima and Haruna Matsumoto sat together, listening to the discussions around them. Both of them were very excited, especially Yukari Kojima.

"This atmosphere is truly worthy of an idol who can perform at the Tokyo Dome! It's so lively!" Matsumoto Haruna whispered to Kojima Yukari.

Yukari Kojima, who had come to see her idol again, immediately nodded, her eyes fixed on the stage, afraid of missing a single second: "SKG is the second group to be formed, and its strength is top-notch among the sister groups. Besides, Nana-chan is here too. I think with Nana-chan's strength, she could hold her own solo dome concert without any problem!"

"That's an exaggeration. Although I know Miyamoto Nana is amazing, it's still not enough for her to hold a concert at the Tokyo Dome level all by herself." Matsumoto Haruna said with a smile, and she had a clearer understanding of the fact that her best friend was a die-hard fan of Miyamoto Nana.

Then Matsumoto Haruna looked around, trying to observe the people around her and memorize their appearances so she could use them as material for future essays.

Just then, her eyes lit up.

She saw someone who looked somewhat familiar.

"Look over there, isn't that someone we know?!" Matsumoto Haruna gently tugged at Kojima Yukari's sleeve and pointed in that direction. Kojima Yukari looked over with some confusion, then her eyes lit up: "Ah, it's Miyamoto-kun's older sister!"

The last time she went to see Miyamoto Sei, she and Matsumoto Haruna were received by this person. Because he looked very similar to Miyamoto Sei, the two of them had a deep impression of him.

I never expected to see each other here, at a concert at Nagoya Dome!

Just then, the other person said something to another girl next to them. Looking at the girl who was obviously shorter and whose appearance was somewhat similar to Miyamoto Sei, the two of them immediately made a guess.

Both of them knew that Miyamoto Sei had a younger sister, and it was obvious that this girl must be Miyamoto Sei's younger sister.

"I never expected that Miyamoto-kun's older sister and younger sister would both come to the SKG concert!" Matsumoto Haruna said with a smile, glancing at Kojima Yukari. She noticed the latter's eyes were darting around, clearly searching for someone, but from the slight disappointment in Kojima's gaze, it was clear she hadn't found them: "Miyamoto-kun isn't here..."

“Didn’t you say you were busy with film work or something? With how serious he is about his work, he wouldn’t take a day off.” Matsumoto Haruna said with a smile, “Unlike us who are still in college, he’s already a working professional.”

"Um……"

Meanwhile, Rina Miyamoto and Yukiko Miyamoto, who were some distance away from Yukari Kojima and in the front row, were excitedly watching the stage, with Yukiko Miyamoto being much more excited than Rina Miyamoto.

"Sister, do you think Nana-chan will be a little different from usual today?!" Yukiko Miyamoto asked Rina Miyamoto.

"Different? If we consider her attitude towards performance, she's always at 100%, so shouldn't it be the same?"

"That's not right either. Nana-chan is also constantly working hard to improve her skills, so even though it's always 100%, there will definitely be differences!" Miyamoto Yukiko shook her head: "I think she'll have a stronger presence!"

"Aura? Tell me what aura is?" Miyamoto Rina asked with a grin.

"Well, well..." After muttering for a while, Yukiko Miyamoto immediately surrendered: "I don't really understand either, but it's just a strange force field, or maybe a magical power? I've seen it, a lot of people say that this is the key to becoming a top star, it's about having your own aura!"

Listening to her sister's words, Miyamoto Rina smiled and nodded slightly: "Your understanding is actually not wrong. Aura is indeed very important, just like the sun. The radiance it emits is the aura of the sun!"

"The radiance of the sun?" Miyamoto Yukiko seemed to understand, but she quickly laughed: "Then Nana-chan's definitely not the sun, because she's destined to become a star among stars!"

Rina Miyamoto smiled without saying a word, but in her heart, she agreed with her sister's words.

The sun? His younger brother is no longer the sun. On stage, he has already surpassed the sun, and his goal is to become the one who can illuminate the sun!

Thinking about this, she found herself unable to contain her excitement.

Amidst much discussion, SKG's Nagoya Dome performance finally began.

This wasn't the first time Miyamoto Sei had performed on such a massive stage in such a prestigious venue, yet it still filled him with immense excitement.

Although he participated in this performance as a part-time employee of SKG, it did not affect his feelings about the place at this moment.

The roar of more than 50,000 people seemed to scatter the clouds in the sky, making the sky clear and the weather, which was originally a bit cold, feel warm today!

Looking at the large audience in front of him, Miyamoto felt as if he had returned to the past. It was as if he had come to the place where he first stood, looking at the audience with a nervous heart, worried that he might be exposed.

My heart was still pounding wildly, as if it were about to burst out of my chest. I was indeed nervous, but this nervousness was different from before. It wasn't fear of being exposed; it was excitement.

I stood once again on a stage of unparalleled grandeur, on the stage of Nagoya Dome, facing an audience of over 50,000 people, all watching me dance!

As always, Miyamoto Sei adjusted himself to his best condition.

The combination of music and body had been trained for a long time and had become an instinctive movement. The flexibility and resilience of the body were displayed at this moment, and under the lights, the perfect figure was reflected in everyone's eyes.

Her body felt incredibly light, every movement was effortless and natural, without the slightest stiffness or rigidity. Accompanied by the cheers of the surrounding audience, the blood in her body was flowing wildly, as if she had received a blessing.

This was the aura of tens of thousands of people, and the atmosphere unique to this moment. A wave of fervent energy rolled across the scene, sweeping everything away.

At this moment, he had no aura, no sense of being number one, and didn't want to care about anything else. All he wanted was to be here, to stand on the stage, and to follow his own emotions to showcase what he had learned.

But these were the very things that had been the focus of these days, and with each experience, they manifested themselves in this moment, as if they had become second nature.

Jurina Matsuda felt the heat emanating from the surroundings, the sense of oppression—no, it wasn't just oppression, but also a feeling that it could carry everyone forward together!

Not only did Jurina Matsuda sense this, but Rena Matsuda also sensed it, even if only for a moment, she clearly felt it!

This feeling... The two of them couldn't help but recall how they felt when they performed with the top members of SKR headquarters, especially when they performed with Higashi Hisaji Ogiko and Naoki Sakurako!

Has she grown to this level already?! Nana-chan!

Nanase Touka could also feel this scorching aura, as if it were burning her. It was fiery hot, and even if it was only for a moment, she could feel the aura that was declaring war on the surroundings!

She looked at the people around her in surprise. Their eyes seemed the same as usual, but the feeling was completely different. Just one glance was enough to draw her eyes in, as if they were giants occupying the entire stage!

Senior Nana, is this the aura you were talking about?!

"Isn't this great? Even through the screen, I can feel the aura emanating from her." Risa Amagai looked at Miyamoto Sei on the screen and smiled. "Indeed, spending almost half a year having you take on this role was the right choice!"

Subaru Hasegawa, standing to the side, was also utterly shocked: "This... how long has it been? The others have honed their aura through years of experience! And she... she just possesses it?!"

"Because she was scared by Sakura back then," Risa Amagai said. "Back then, when it was the checkered pattern, Sakura was provoked by her somewhat uncontrollable aura, and she just exploded, which scared her half to death."

"Was it because of this kind of stimulation that you were able to grow to your current level?"

“It’s not just that. With that kind of stimulation, plus experiencing different venues, different stages, different audiences, and different requirements, she naturally grew,” said Risa Tempel. “And as she grew, she also influenced the people around her, whether it was SKG, AJS, or DJH, allowing them to grow as well.”

"Then why don't Mika Komatsu and Miyu Nagasu need this kind of experience?"

“Komatsu’s aura has always been there and has been constantly being refined. She has never lacked confidence. As long as she resolves some of her inner issues, she will naturally be able to stand there,” said Risa Tenbei. “As for Eian, the moment she broke away from Miyamoto and was willing to stand on the stage alone, her aura naturally took shape. It’s just a matter of time before it gets stronger.”

At this point, Risa Amagai smiled and said, "I called Nanase back and didn't let her take on the DJH part-time job for the same reason. For this child, it is also a very important experience to move forward on her own as a fledgling."

"And this performance..."

"Not bad, isn't it?" Risa Amagai looked at the screen and could clearly see Nanase Touka's momentary surprise, which made her very happy. "It's obvious that she, who was closest to her, also sensed the change in her senior."

Inside the training room, Naoki Sakurako was watching a live stream during a break. When she saw the performance of the people on the field, her eyes narrowed slightly.
