G. Analysis

"I just want honesty. What is Tamaki's relationship with Takumi?"

Seeing the school uniforms that Tamaki, Takumi, and Rin were wearing, which were also Kenkyo's school uniforms made me suspect that there was actually a special relationship between them.

To Kenkyo, he was indeed their 'senpai or senior'.

"Kenkyo-senpai who killed my best friend, why is it my lover that you accuse?"

Oh so that's it? I understand now. I glanced at the finger of her left hand, there was a bandage.

"Knife wound, eh?" I asked Rin.

"W-how ... yes, it got hit by a knife."

Alright, now I know the motives and tricks of the perpetrators. If yesterday I thanked mother, now maybe I will thank Kenkyo.

Sometimes female gossip helps too.

***

I came out of Mitsuki-san's apartment. Then slowly walked down the hall of the apartment. My destination is Takumi's room.

My detective instincts were telling me again, it was the teenage boy who did it. I once overheard Tamaki and Kenkyo's conversation. Tamaki complains to Kenkyo that Takumi always 'annoys' him even though he has Rin.

If my guess is correct, then he is the real culprit.

***

"So, why did you call me here, Kimu-san?"

The question left Takumi's mouth. The curly teenage boy looked at me expressionlessly standing right in front of the guardrail.

I took a deep breath, putting on a serious face.

"So you accuse me of being the culprit?" asked Takumi flatly.

Bingo! I haven't accused him yet, but he already knows I'm going to say he did it.

Stupid! Or was it on purpose? Who knows.

I nodded.

"You are the culprit, Kaboshi Takumi."

He looked at me defiantly. Slowly, both hands lifted up to fold in front of the chest.

"How could I drop Tamaki? I wasn't on the roof when Tamaki fell. After all, isn't it Kenkyo-senpai, your nephew who knocked down Tamaki?"

I winced. There seemed to be something wrong with what he just said. Nephew he said? Do we both really look like Uncle and nephew? Oh, it's okay. It's not bad either, the important thing is that they don't think Kenkyo is my daughter.

"Isn't that right? Tamaki fell because of Kenkyo-senpai?" he said again.

"No." I argued. "Tamaki-san fell off the roof by herself... Oh no, I was wrong. She fell because of an invisible hand that knocked her off the roof with your trick." I glared at him.

"What do you mean?"

"What do you mean?"

I smiled happily, "Glasses are the main point of this trick. I'm right, right?"

Takumi chose to remain silent.

"In Tamaki's room, there is a letter written in Kenkyo's name telling him to go to the roof. It's likely that Tamaki is interested in going there, because the perpetrator who sent it uses Kenkyo's name."

He's still silent. He confronts the official detective. Moreover, he brought Kenkyo. Really stupid, right? I checked everything. I already knew, and there was no reason he could deny it. He thought I wouldn't go all the way to the root? Very stupid!

"Coincidentally, ah no! According to your plan, Kenkyo went up on the roof, because you know it's a habit when I come to visit on Thursday, then Kenkyo will go to the roof to pick up my coat which he dried at night.

"Okay, going back to Tamaki, naturally he must be looking for Kenkyo who hasn't come yet. She must have been around looking for Kenkyo. And when Tamaki was in front of the guardrail, Tamaki saw someone waving at her. Because of her blind eyes far away, Tamaki doesn't even know who is waving at her, whether it's Kenkyo or who. That's why the girl wears glasses to see the person waving at her."

"Then what's weird?" cut Takumi quickly.

I saw his face changed slightly made me smile.

"That's the main point. Look, what if we change the lenses of Tamaki's glasses that don't match her vision? Tamaki will lose her balance because her blurry vision makes her head spin."

"Then, to balance her body so she doesn't fall, she grabs hold of the railing - which is in front of her - without realizing that the fence will immediately fall off when touched. And that made her lose her balance and end up falling too."

I continued to analyze while looking at Takumi who was looking down. It seemed he had given up. I continue my analysis again.

"You and Tamaki-san are 'good friends', aren't you? You often visit Tamaki-san's place. So, it won't be difficult for you to change Tamaki-san's glasses."

"The proof?" asked Takumi. "What's the proof? You just explained a trick that anyone can do, which was right where Tamaki could see it at the time. That means, apart from me, there are other suspects, Rin, her father and you too, right?"

"Maybe you're right. Anyone at the crime scene could be the perpetrator who killed Tamaki-san. The perpetrator must be in the vicinity of the crime scene, because in addition to lure the victim to touch the guardrail, the perpetrator must exchange the victim's glasses," I said walking closer.

I, walked until my body was now right in front of him and looked at him sharply and coldly.

"While on the roof, I saw you hiding something you took from the crime scene, when everyone's attention was on Kenkyo-chan."

I looked at Takumi's bandaged fingers.

"Your right finger was cut by the shard of the lens glass, right?"

Takumi touched his finger,

"I cut my finger when I learned to cook," Takumi said quietly.

"You're lying. If you cut your finger with a knife, it should be the finger on your left hand, not your right hand, unless you're a left-handed person. However, in fact you're not right-handed. The wound on the finger was obtained when you rushed to pick up shards of glass. while everyone's attention is on Kenkyo-chan. You can't make excuses anymore, Takumi-san, give up!"

silence.

He was just silent.

I pulled his curls.

"Confess or you will suffer the same fate as Tamaki-san!" Threatening me.
