In this crossover anime, I fight against the supernatural in my everyday world.

"Okay, see you Monday."

After a brief greeting to Yukino, Yohoshi left the Superpower Club's activity room.

He didn't leave the school directly, but followed the faint, melodious piano music along the corridor to the door of another activity room.

Ye Xing slowly opened the sliding door, revealing a beautiful scene with an artistic flair.

A cool breeze, typical of early summer evenings, blew in through a window that was slightly ajar.

Wearing the uniform of Soubu High School, her two long, beautiful legs were covered with black stockings, and her smooth, long black hair was not specially styled, but simply draped casually over her shoulders.

Ten slender, white fingers, like elves, danced gracefully yet powerfully across the black and white piano keys.

Touma Kazusa was so engrossed in her performance that she didn't even notice someone entering the room.

She breathed a sigh of relief after the piece was finished.

"Night Star?"

She saw Ye Xing sitting there, and a smile couldn't help but appear on her usually icy and delicate face.

"sit down."

"I'm already seated."

Seeing Yosei trying hard to suppress her laughter, Touma Kazusa blushed slightly and made conversation.

"Hmm... Just sit down."

After saying that, Touma Kazusa tucked her long black hair behind her ear and remained silent, unsure of what to say.

She has a rather twisted personality.

His attitude towards Ye Xing was quite complicated.

On the one hand, they want to be by each other's side every moment, silently watching over each other.

On the other hand, Touma Kazusa is very insecure.

Compared to the perfect senior Mai Sakurajima, there is always the calm and collected Rio Futaba, the cute and kind-hearted Miko Yotsuya, and the gentle and considerate Yui Yuigahama.

Can someone like me really be worthy of Ye Xing?

Touma Kazusa only knows how to play the piano.

She can only interact with the piano.

At this moment, she once again placed her hopes on the piano.

"Night Star..."

Touma Kazusa spoke softly.

"What musical instruments do you play? Besides the suona?"

"Are you discriminating against the suona?"

"Well... not exactly."

Touma Kazusa pursed her lips, a complex look flashing in her eyes.

The suona, this musical instrument...

Who could possibly match this?

Unless Touma Kazusa gives up the piano and switches to playing drums.

That way, I can form the strongest wedding and funeral band at Soubu High School together with Yoruichi.

Isn't this even more intense than End of the Band?

"How about... I stop playing the piano and start practicing gong and drumming instead?"

Seeing Touma Kazusa's very serious expression, Yosei was taken aback for a moment, then chuckled and waved his hand.

"You really want to do that?"

To his surprise, Touma Kazusa nodded very seriously, her voice tinged with a hint of loneliness, and her tone even sounded somewhat humble.

"Yes, really, I'd like to do something with you, is that okay?"

Faced with Touma Kazusa's humble request, Yohoshi responded with a smile.

"That's possible, but you don't need to switch careers to playing drums and gongs. I can play other instruments."

"What are the other musical instruments...?"

Touma Kazusa glanced at Yohoshi and spoke cautiously.

"Could it be... a kazoo?"

"what."

Ye Xing looked disgusted.

"Touma-kun, is this how you see me?"

Touma Kazusa looked embarrassed and was about to explain when Yosei laughed.

"I do know a little about the kazoo."

"But this time I'm talking about the guitar."

Touma Kazusa nodded slightly, showing little surprise.

"Yeah, that's good."

She felt that Ye Xing's original image should be that of someone who plays the guitar.

As for the suona...

Although she hadn't seen the other person play it in person, just imagining the scene made her almost lose control.

"Then when you have time, can we practice together?"

Upon hearing Touma Kazusa's question, Yohoshi smiled.

"You want to form a band?"

Touma Kazusa pursed her thin lips, and a rare hint of shyness appeared in her usually sharp, delicate, and slender eyes.

"I...don't want to form a band."

"I just want to form a band with you."

.......

Two days later, on Sunday, at Kyoto City Hospital.

"I'm sorry to trouble you today."

Kawasaki Saki, holding her younger sister Kawasaki Kyoka's small hand, looked embarrassed and shy, and whispered something to Yohoshi.

The latter waved his hand and laughed.

"It's okay, I was planning to come here today anyway."

Kawasaki Kyoka's face was flushed, and she looked a little tired, but she still stretched out her left hand and said to Yoru.

"Big brother, can you hold my hand?"

"sure."

Yoru took Kawasaki Kyoka's left hand, a gesture that made Kawasaki Saki blush slightly.

From an outsider's perspective...

It's like a young couple bringing their young daughter to the hospital for a checkup.

Saki Kawasaki couldn't do anything about it either.

Not only did her younger sister suddenly catch a cold, but after she brought her to the hospital, the sister kept making a fuss, saying she wanted her older brother to come along too.

Saki Kawasaki has a fatal weakness.

That was his younger sister.

Unable to refuse the other party's coquettish plea, she could only swallow her pride and call Ye Xing.

"Big brother is so nice."

Kawasaki Kyoka's little face was adorned with an innocent and bright smile. Then, she looked at Yotsuya Miko and Futaba Rio standing behind Yohoshi and muttered something under her breath.

"It would be even better if only the older brother came."

Both Miko Yotsuya and Rio Futaba were speechless.

What can we say to such young girls?

Rio Futaba and Miko Yotsuya watched as Yohoshi and Saki Kawasaki flanked the bouncy Kyoka Kawasaki, a heartwarming scene, yet a hint of wariness flickered in their eyes.

Is it possible...

Is Kawasaki Saki using her younger sister as a wingman?

Given their straightforward personality, they shouldn't be capable of doing something like this.

Wait a moment.

Looking at Kawasaki Kyoka's innocent smile, Futaba Rio suddenly had a terrifying thought.

She tugged at Yotsuya Miko's sleeve and lowered her voice.

"Could it be... that Kawasaki-san is actually this little girl's wingman?"

"What!?"

Even when faced with terrifying evil spirits, Yotsuya Miko remained unfazed, but she was completely stunned by Futaba Rio's astonishing words.

"No...no way? It's so small..."

Rio Futaba sighed softly, glancing meaningfully at Kyoka Kawasaki, who was staring intently at Yoru's profile.

People do grow up.

"You two."

at this time.
