Refuse to allow Conan to join the main storyline

Because he got on the elevator after Ogura Takuya, when the elevator reached the fourth floor, Koizumi was the first to walk out. He didn't see any suspicious people or police in the corridor, so he just randomly chose a direction.

She heard Ogura Takuya get out of the elevator behind her, stop there for a while as if he was trying to identify the direction, and then walked towards her wearing two men in black suits.

Koizumi walked deliberately slowly, looking up and down at the name tag hanging on the door as he walked. He allowed the three people behind him to overtake him and walk to the front, stopping outside a ward.

Under the gaze of the two men in black, Koizumi calmly pushed open the half-open door of a nearby ward and walked in.

There was no one in the ward, maybe the patient had left temporarily. Koizumi closed the door and stood at the doorway, listening attentively.

The man in black in the corridor pushed Ogura Takuya into the ward, looked around and saw that no one was paying attention to them, so he also slipped into the room.

Koizumi quickly came out of the ward where he was hiding, sat down on the bench at their door, and listened to the noise inside.

"Look for it quickly while the cops are away, hurry up!"

"Damn, what are you doing touching her, you bastard? You're rummaging through her clothes!"

After a rustling sound, Ogura Takuya stammered, "Big, big brother... really not, I guess it really fell at the scene and was picked up by the police as evidence."

Koizumi was relieved to hear this. It seemed that Aoi Echizen would not die until the USB flash drive was found.

She stood up and was about to go back the same way to leave, but when she looked up, she saw two familiar faces walking out of the elevator.

Furiya Rei and Matsuda Jinpei finally showed up!

Koizumi's face instantly darkened and he cursed wildly in his heart.

You two unorganized, undisciplined, and unmanageable bastards actually ignored the instructor's orders and came over to hinder my actions! I will send a message to Onitsuka later and ask him to put you in solitary confinement and let the school punish you! I will be sorry for my super vengeful personality if I don't leave you with a memorable lesson!

The two people opposite also saw her.

Jinpei Matsuda simply raised his eyebrows and continued walking forward as if he didn't know Koizumi.

Fūya Rei's gaze was obviously shaken, but seeing that his companions were still insisting on taking action, he could only endure Koizumi's unfriendly gaze and keep moving forward.

When Koizumi heard that the three people inside the door were preparing to retreat from the room, he immediately became a little anxious.

She walked towards the two people, pushed open the door of the ward where she had been hiding, and tilted her head slightly towards the two people.

Jinpei Matsuda wanted to ignore her request, but unexpectedly, Furukaya Rei pushed him into the room.

Matsuda Jinpei was caught off guard and stumbled almost falling. When he turned around angrily, he saw the two men also walked in. The door had been closed by Koizumi.

Koizumi's expression was clearly unhappy: "Did you fail to deliver the message, or did you disobey orders?"

Furuya Rei and Matsuda Jinpei looked at each other...

The case is solved. That’s what it is.

When they received the call in the hospital lobby just now, the two were still wondering why Onizuka suddenly called them and asked them to return to school immediately.

Koizumi didn't intend to say much to the two people. After saying this, he made a "keep quiet" gesture, stood by the door and listened carefully to the noise outside, and then he was startled by the people who were talking outside.

The voice that she remembered so vividly said, "Did you find it?"

"No, big brother. It must have been taken away by those cops as evidence."

Koizumi couldn't help but tense up and swallowed.

Sure enough, she said that the power to monitor Ogura Takuya was a bit weak, and it turned out that the core figure had not shown up.

Remembering the legendary cautious character of Gin, she guessed that this person might have come up the stairs alone, and perhaps had deployed personnel at other exits of the building to prevent Ogura Takuya from escaping.

Koizumi's eyebrows suddenly twitched and he turned his head sharply to look at the two police academy students standing in the room.

She suddenly had a bad feeling.

If Gin suddenly decided to check nearby rooms to see if there were any police officers watching or eavesdropping...

World will, you won’t cause any trouble!

No, you can't gamble!

Furiya Rei and Matsuda Jinpei were sensitive enough to sense that the woman in front of them had discovered something, and her expression suddenly became tense. Her eyes drifted across the room, and then she pointed to the locker by the wall and said to them anxiously, "Hide it!"

While Matsuda Jinpei was still hesitating, Furuya Rei had already opened the door of the locker and quickly stuffed himself and his companions into the small space.

Koizumi stared at the two people with his most serious eyes and silently warned them with his mouth: "Quiet!"

Then she closed the cabinet door gently and sat down on a chair nearby.

The moment she sat down, the door of the ward was gently pushed open from the outside.

The two people in the locker heard a man's cold voice say, "Sakurai Izumi? This is really an unexpected gain."

Due to the obstructed vision, through the ventilation holes, Furiya Rei and Matsuda Jinpei could only see that it was a man wearing a black windbreaker and black leather shoes.

A faint smell of cigarette smoke drifted in the air.

Sakurai Izumi's voice said: "Do you have any manners? Don't you know that you can't smoke in the ward?"

The man sneered: "You don't seem surprised to see me?"

"Tsk, that old fellow of mine still won't give up? Can't you just treat me as dead?"

This palace!

Furiya Rei immediately remembered that this was mentioned in the secret letter. This was the name of a senior member of the organization, the person who had once conducted drug interrogation on Sakurai!

"Since you know, come with me."

The man raised his hand slightly in his windbreaker pocket, and both Kouya and Matsuda could see that he had clearly pointed the pistol hidden in his pocket at the person in front of him.

"Haha, no."

There was a light "click" sound, and Koizumi laughed nervously. She said cheerfully, "How about giving it a try and see who dies faster?"

The room became quiet and the air seemed to be stagnant.

About half a minute later, the man took the lead and lowered the muzzle of the gun in his coat pocket: "I have already delivered the message, you can do whatever you want."

Koizumi said impatiently, "Okay, okay, got it! Ah, how about you tell that old guy to let me kill him once, and I'll agree to his cooperation request."

The man sneered: "I am not your messenger."

After saying that, he walked out of the room with steady steps and closed the door gently.

The room returned to silence again. Koizumi didn't say anything, and the two people in the locker didn't come out rashly.

After waiting for a while, the door of the ward was opened again, and a voice said, "Hey, who are you? What are you doing in my ward?"

There were two light knocks on the locker door, and Koizumi said softly, "Come out."

Only then did Fūya Rei and Matsuda Jinpei squeeze out from the closet.
