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

The genuine Onimaru Kunitsuna has actually been stolen.

As for why he concealed this matter, Light Yagami could probably guess a few things.

This also confirmed the conflicted and helpless look in his father's eyes.

So now, Yagami Soichiro says he has applied for leave, and the Metropolitan Police Department's higher-ups have approved the application.

This suggests that either the Metropolitan Police Department has no intention of launching an investigation, or they haven't yet received any leads that they could investigate.

It's very clean.

As Soichiro Yagami's son, Light Yagami knew very well how high-level his father's criminal investigation experience was.

Even so, they were still helpless against that guy.

He truly is someone who walks the same path as me, with the goal of eliminating evil and changing this corrupt world.

Meanwhile, Soichiro Yagami was unaware that his seemingly perfect son, whom he was extremely pleased with and who was the envy of all parents and whose goal was to become a member of the Metropolitan Police Department, had secretly betrayed him.

.......

Meanwhile, at Night Star's home.

After dinner, Yui Yuigahama and Miko Yotsuya went home first.

It's spring break after all, so they can't stay out too late.

Only Rio Futaba, Mai Sakurajima, and Yohoshi remained in the living room.

"Mai-senpai".

Rio Futaba looked at Mai Sakurajima, who had taken off her apron and was sitting on the opposite sofa with her two long, beautiful legs crossed, completely at ease as if she were sitting at home, and asked casually.

"It's almost eight o'clock. If you don't go home soon, your family will worry."

Mai Sakurajima smiled upon hearing this and asked a question in return.

"What about Futaba? Aren't you going back?"

Rio Futaba took off her glasses and said calmly.

“I live alone, so I can stay out later.”

A subtle, almost imperceptible glint flashed in Mai Sakurajima's eyes as she maintained her perfect smile and replied.

"What a coincidence, I also live alone."

"How long does Mai-senpai plan to stay?"

"So, Futaba, how long do you plan to stay?"

Rio Futaba remained calm and composed, just like always.

Mai Sakurajima's face still had that flawless, sweet smile that would be captivating to anyone who saw it.

Neither woman showed any difference in expression from usual.

But the atmosphere in the living room became inexplicably tense.

Rio Futaba came today and has no intention of leaving.

If Ye Xing doesn't come to my house, I can just stay at his house for one night, right?

Skillful.

Mai Sakurajima didn't plan to leave today either.

She's used to living there; towels, toothbrushes, and changes of clothes are all kept at Ye Xing's house.

Now the question is.

Rio Futaba didn't want Mai Sakurajima to know that she planned to stay at Yohoshi's house. After all, it was too embarrassing for her to say that a man and a woman were alone together in a room.

but.

Mai Sakurajima didn't have this concern.

"Futaba-kun..."

Just as Mai Sakurajima was about to lay everything out in order to discourage Rio Futaba, the doorbell rang suddenly.

Ye Xing got up, went over and opened the door, only to find someone she hadn't expected standing outside.

"Good morning."

Touma Kazusa was dressed in simple black trousers and a black short-sleeved shirt, and because she was going out at night, she also wore a short jacket.

After greeting her, she put her two slender, white hands together and breathed into her palms.

"Touma-kun?"

Yohoshi originally thought that the person standing outside the door would be either Yagami Light or Haruno.

To my surprise, it was Touma Kazusa.

How did you know where I live?

Touma Kazusa's expression was so emotionless; she simply replied indifferently.

"I asked Hiratsuka-sensei. She heard I needed to talk to you and told me directly."

Upon hearing this, Ye Xing thought to himself, "This Hiratsuka Shizuka really won't give up until she's completely cornered."

If Touma Kazusa came to visit at any other time, that would be fine.

But...

With the entryway as the dividing line, these are two completely different worlds.

A silent battle is currently underway in the living room.

Of course, Yohoshi couldn't let Touma Kazusa stand outside, so she could only turn slightly to the side.

"Let's talk after we come in."

"it is good."

As Touma Kazusa entered the house, she immediately saw the can of Pepsi on the shelf in the entryway.

A complex look flashed in her eyes, but she didn't say much. She just looked at Mai Sakurajima and Rio Futaba sitting in the living room.

"Who are they?"

Player Touma Kazusa joins the battle.

Let me introduce you to them.

Yohoshi led Touma Kazusa through the entrance hall and into the living room.

"This is Mai Sakurajima, a senior who is one year ahead of us."

Upon hearing his explanation, Rio Futaba thought to herself, "Isn't this just unnecessary?"

Even someone as withdrawn and unsociable as myself had heard of Mai Sakurajima's name.

As a student of Soubu High School, how could Touma Kazusa not have heard of her?

Unexpectedly, when Touma Kazusa heard the name Sakurajima Mai, she didn't even look away, her gaze remaining fixed on Yohoshi, and she only gave a brief one-word response.

"Oh."

Mai Sakurajima was also taken aback, not expecting the other party to react this way.

Yohoshi knew that, given Touma Kazusa's personality, she probably didn't really know Sakurajima Mai.

After all, in the other person's life, there was only the piano; nothing else mattered.

Mai Sakurajima and Rio Futaba, however, had more complicated thoughts.

Oh, what do you mean?

Could it be that Touma Kazusa actually knows Sakurajima Mai, but has already sensed the tension in the air and is therefore preparing for battle, unwilling to show surprise in front of the enemy?

What remarkable composure!

Even in terms of momentum, they were unwilling to be at a disadvantage.

This is a formidable opponent!

"This is Rio Futaba, and this is my deskmate in class, Kazusa Touma."

Yohoshi led Touma and Kazusa to sit down on the sofa. Before he could speak, the latter said calmly.

"You have a club that's about supernatural events, right?"

"Correct."

"That's good, I have a request."

Upon hearing the word "commission," Rio Futaba and Mai Sakurajima exchanged a glance, instantly understanding each other's meaning.

Let's not argue about it for now.

Business matters.

"Oh?"

Ye Xing looked quite interested.

"What exactly is the commission?"

Without hesitation, Touma Kazusa spoke up directly.

"The piano in my house always starts playing for no reason. Oh right, I live alone, so there's no possibility that anyone else is playing it."

Hearing the familiar line about living alone, Rio Futaba felt a mix of emotions, but she still asked.

"When did it start?"

Touma Kazusa glanced at her, thought for a moment, and then said calmly.

"Probably... before the start of the school term."

"what?"

Mai Sakurajima and Rio Futaba were both stunned.

No, before the start of school?
