After some time, Kazuya left Yui at the bed and gone to the rooftop. Since Aki and him agreed to meet there. At the rooftop, Kazuya supposed to know Aki's background check.
"Aki, did I kept you waiting?"
"No, I just arrived here. Now, let's get to the point. The matter of Yui Kousaka's background check."
Kazuya gulped down, and stood firm and readied himself for Aki's report.
"Honestly, It's really hard doing background check when she was forgotten. That's why I first checked her papers. There's not much you can say about her birth certificate. But her hospital records are different."
Aki stared at Kazuya, as if Yui's situation is a real serious one. Then, she continued her report.
"Apparently, she has two phobias, Claustrophobia and Nyctophobia."
"But if she has nyctophobia, then isn't she supposed to have fear of darkness? When we gone out at night, it doesn't seem that she has that."
"That's because It's already treated. The problem is Claustrophobia. If her Claustrophobia strikes, her Nyctophobia comes back too. But needless to say, as long as her Claustrophobia doesn't strike, Nyctophobia wouldn't strike too."
Kazuya just touched his chin, and asked Aki to continue again. He's trying to connect the details to Yui's problems.
"I continued my background check and discovered the work oh his father, and I have forgotten to say that her mother had passed away. Her father is making her daughter live alone since she's a celebrity, all in all."
Kazuya released his hand from his chin, then thought to himself "Must be tough."
"Let's go back to the father's work. I asked his boss and he said that because of work, he needed to change places almost every year, and it started at Yui Kousaka's third year of elementary."
"Third year of elementary?"
Now it makes sense! Now it connects! The reason of the changing of people at every picture is because she's always changing places every year. But is it connected to Yui's problems? Kazuya signaled Yui to continue on her report.
"Then, at her 1st Year of High School,she applied at an agency and later on, became a rising star celebrity."
From Kazuya's memory, Aki is alone at her first-year of high school. Why is that? I could be that It's still the first day of school so she still didn't gained friends. But when he remembered that picture, that feeling started again. What is that feeling? Something is strange.
"After I discovered these facts, I did not discovered anything after that. That's the end of my report."
Kazuya sat at the floor and tried to think with his brain. He's trying to connect the clues he have so far. So far, there are certain things he know. It was her phobia, the fact that she changed places almost every year, the pictures.
Only certain things connected, but some things did not. Kazuya still can't draw conclusions. So he said to Aki that they're dismissed for today.
With that, Aki left the scene and left Kazuya who is still thinking Yui's problems.
"There's still something left. One more puzzle piece, and I can know the problem."
After that, Kazuya left the rooftop and gone to Yui's condo.
+++++
"Owaaaaa~"
Yui yawns as she rise from her bed. It seems she slept really soundly, despite being really scared last night. Yui stood up, and walked towards the living room.
As she walked to the living room, she saw Kazuya flipping the pan because he's cooking an egg. While he's flipping the pan, Kazuya noticed her and cheerfully greeted her:
"Oh, your awake already? Good morning, I will prepare breakfast so please wait in the table."
Yui received the greeting, and she smiled as she heard that words. After some while, Yui returned the greeting:
"Yeah, Good morning."
"Oh, your much cheerful now. Yesterday, your like an emotionless doll, not saying anything and just reading your book."
"Is that so? I'm sorry for the trouble."
Yui is flushed red after hearing her behavior yesterday. This is Kazuya's last day. If he doesn't do anything, Yui Kousaka will explode. He has to find the problem no matter what.
"Hey, Kazuya, I heard that a Cultural Festival will be held tomorrow. I don't really know what is it, I only heard it at the streets, but It seems fun! Let's go tomorrow, the two of us!"
At the time Yui finished her sentence, Kazuya already finished cooking the breakfast. He put it at a plate and served it at the table.
"Here, eat up!"
Kazuya said as he took a seat in front of Yui. It's clear that Kazuya evaded the question. But Yui is still not eating and repeated her question once again.
"Hey, did you hear what I just said? Let's go at the Cultural Festival!"
"I'm sorry, I don't think I can come with you."
Kazuya looked at the ground with eyes of sadness. Yui noticed that, and took her utensils and took a bite at her breakfast. The breakfast is just Sunnyside up egg, bacon, toasted bread and a small bowl of soup.
"It's delicious! Kazuya, your cooking is delicious!"
"What are you saying, Yui? This dishes are just basics."
With that, the two changed the conversation. The conversation earlier was forgotten, and they didn't brought it again. After they finished eating, Kazuya washed the dishes then took a seat to think the problem again.
"Kazuya, aren't you going to school? No one knows me there, so I don't really want to go."
"Sorry, I'm not feeling well. So I'm going to skip school today."
In reality, Kazuya doesn't want to go to school because he want to spend his time thinking about Yui's problem. But one thing came to Kazuya's mind.
"Hey, Yui, you want to know yourself, right?"
"Yes, I actually want to know. It's actually hard not knowing yourself. The only things I'm certain about is the fact that I'm afraid of the dark and tight places. In addition, I read books to know some certain things too."
"Oh? Really?"
After Kazuya said that, he took a bite from his biscuit(He saved it for dessert), then continued his statement.
"Then, do you want to go somewhere? After we finished eating, that is."
While chomping her cookies, Yui nodded slightly. With that, the two of enjoyed their meal. When they finished finished eating dessert, Kazuya left the condo and Yui followed him.
"Almost there. I can solve this case. If I'm lucky, maybe I can find the answer there.
Kazuya proposed that the two of them should go at that place. He thinks that the final puzzle piece can be found there. Betting at that kind of outcome, Kazuya and Yui heads there.
+++++
"So this is the place you want to go?"
Yui said as she stared at the huge stadium in front of her. This is where Idols perform. So Kazuya brought himself and Yui here, hoping to find some clues.
Although, there's no performance going to happen, they entered the stadium and took a seat at the front.
"Yui, let's go at the stage."
"Okay."
Kazuya and Yui have gone to the stage to see the number of seats. When they climbed the stage, Yui was surprised at the number of seats. It was so many, there's no way you can count them.
"There's so many seats here, it means that many people are coming here, right? It must be amazing, just standing here while imagining that many people will come gives me the chills."
Kazuya didn't replied at her statement. He just stood beside her, smiling while lending an ear to what she's saying.
"Kazuya, you said that a person will dance and sing here to entertain the crowd, right? I think that guys must be amazing. You also said that I'm one of them, but I can't imagine myself dancing and singing here."
"No, Yui, your one of those amazing people."
Kazuya interrupts Yui's speech and said these words. Yui was just staring at Kazuya, because she can't understand these words. Why is she one of those? What's so amazing about her?
"Like I said, your one of them. When we first met, you cared for your fans so much that you'll go and hate me for it."
"No, I will never hate Kazuya!"
"But, you actually did..."
Kazuya is still not finished on his words, Yui suddenly held his hand and looked at his eyes with their faces so close to each other.
"Like I said, I will never hate Kazuya!"
Said by Yui while still holding his hand. After a while, Yui realized what she did just now, and apologized to Kazuya afterwards.
"Like I said, you actually cared for your fans back then. Your worried that they suddenly left..."
While uttering those words, Kazuya realized something, or much to say, he remembered something. The fact that Yui cared about her fans so much. Why is that? Normally, a celebrity will care for their fans, but not as much as Yui.
While still standing at the stage, Kazuya held his chin, and tried to think for an answer. Who knows? This might be the final puzzle piece.
Kazuya tried to think as long as he could. He tried to connect all of the pieces. Her Soul Seal, being obsessed at her fans, having a claustrophobia, always moving places every year, and the strange pictures.
All of this clues, only point at one thing. That's why by putting all of these clues together, you can already draw a conclusion.
"If my hunch is correct, then her problem should be..."
That's right. At this time and day, Kazuya Satoru have already discovered Yui's source of depression.
+++++
The two left the stadium and gone back to the condo.
"Yui, I'm going to the rooftop for a while to get some fresh air."
"Okay, just please don't take too long."
Kazuya climbed the stairs towards the rooftop and saw the figure of a girl that has pig tails hairstyle.
"Aki, we'll now think a plan. Let's operate it the moment we finished our meeting. I don't want to waste any more time."
"Understood. Then, tell me the situation and I'll start to think a plan."
Kazuya told the situation to her and the two of them thought of a plan.
"Okay, let's go with this plan! Let's do this!"
"Kazuya, I have one question."
Kazuya turned his head towards Aki and he nodded slightly.
"If you extract the Soul Seal from her, will she still remember you?"
At that question, Kazuya looked at the ground with his head tilted at the left. But even though he has eyes of sadness, he's smiling.
"I'm sure she's not going to remember me. Because If I extract the Soul Seal, her memories will return. But the memories she made while remembering nothing will be overwritten. So even If she likes it or not, she needs to forget me so she can be saved."
"I see."
With that, Kazuya walked towards the exit of the rooftop and Aki teleported to her position.
"I'll forget Kazuya? What does that mean?"
While Kazuya and Aki was having their meeting, Yui was there behind the door. Since she was worried about Kazuya, she decided to check up on him. Because of that, she heard Kazuya's statement just now.
Kazuya didn't even sensed that Yui was there at the door. That's because he closed all his senses to focus on his thinking ability. When Yui saw that Kazuya is going back, she immediately ran towards her condo. While still running, she thought:
"If I remember myself, I will forget Kazuya? Then, isn't it okay if I don't remember myself? There's no point remembering when Kazuya is the price! I will reject the future where I'll forget about you!"
Yui changed her course and ran towards the exit of the building. She used the stairs, since she's not sure about the elevator. Yui tried to escape from Kazuya. If Kazuya can't catch her, then he can't erase her memories. At least, that's what she thought.
"Yui, we have something to talk about."
Said by Kazuya the moment he entered the condo. When he noticed that Yui is nowhere to be found at the condo, he recollected his senses and memories at the rooftop and discovered that:
"She's there! Yui heard me!"
Kazuya immediately left the condo, then ran towards the exit. Kazuya's physical ability is excellent, or should I say, monstrous so he should be able to catch up to Yui if he knew the direction she ran to. Since he doesn't really know where she went, Kazuya called this certain girl again:
"Aki!"
"Good grief. Good thing that I have rested when you called me."
While Kazuya is running, Aki suddenly appeared beside him.
"Yui heard our conversation so she's escaping from me. We need to find her! There's not much time remaining, so please hurry!"
"Understood."
Aki disappeared in thin air, but Kazuya doesn't even care about it. The only thing he thinks about right now is catching up to Yui. The time is 5:00 PM. The time limit is sometime at night. Can Kazuya find Yui and save her at the Time Limit?
+++++
45 minutes had passed since they started searching for Yui, but she's still nowhere to be found.
"Damn, I don't have any Soul Seal that can help me in this situation!"
Kazuya is at the sidewalk, trying to catch his breath. Running full speed for 45 minutes is already amazing though.
"Yui, is at the stadium! Kazuya, go there!"
Out of nowhere, Aki suddenly appeared beside him. After hearing that, Kazuya gave a "Thanks." then started running again.
"He can run towards the stadium?"
Aki was dumbfounded by what she saw just now. But she shrugged it off, then took a seat somewhere.
"Ahh! I need to rest so I can use my Teleportation again. The rest is up to you, Kazuya."
As Aki just mentioned, Kazuya is really running towards the stadium. Bystanders are thinking that he might be from the Track Team or some other clubs that involve running very fast.
After some running, Kazuya finally reached the stadium, and it took him 15 minutes to do so. But right now, he's crazy tired! But he can't let fatigue to stop him from saving her. So he continued on his way, and entered the stadium.
The time is 6:00 PM, It's already night but Yui is still not exploding. It just means that it's somewhere at night. Kazuya doesn't know the exact time so he needs to make be faster as he can.
As soon as he entered the stadium, the figure of a girl standing at the stage can be seen. Because of the lights, her silky pink hair is shining. Her soft porcelain skin is standing out.
Although, there's no crowd, she's still standing at that stage. Kazuya moved forward. As he clench his fist, the mix of resolve and determination can be felt.
This is the final battle. Can Kazuya save Yui or not?
