I closed the bar today, it's just for us to enjoy. Yuki is trying to communicate with others using a paper and a pen. Now everything is finally peaceful, no more mysteries, no more revelations.

"Iris, there's something I wanted to tell you." Owen is trying to say something, is he going to confess?

"What does thy have to say?"

"Well, I really admire you. And you're cool. And a lot of things too."

Iris looks confused, but Owen prepare himself and finally say it.

"I love you Iris! Do you want to be my girlfriend?"

Everyone is looking at them, after a short moment, Iris finally answers.

"Of course, My person is honored to be with such a reliable man."

We all are clapping at their new relationship. After some time pass, I ask them to come.

"Everyone, come here. I have a surprise." 

Everyone comes closer to me, they all are smiling and happy.

"You all did a lot to solve the mysteries that lied in this hospital. It may be not much after all you did, but I want to give you my thanks and a cake I baked."

"My humble person shall accept your thanks, but there is no need. We investigated these mysteries only to reveal the truth!"

"Thanks, Iris, you really helped a lot."

"The mystery of the ghost girl may be over, but our friendship isn't. We'll still spend time here in our free time."

"You're right, Owen, we'll still stay together."

"It wasn't always easy, but we managed all together!"

"Yes Sebastian, together."

Sofia is holding a paper with "It was a great adventure!" on it.

"It was a great adventure, yeah."

"I'm happy to not be alone now, big sister!"

"I am also very happy, Yuki."

"What about the seventh mystery?"

When Silv said those words, everyone's smile disappeared to let worry and confusion on their face.

"What do you mean? It's over. We found the truth before Kilt did the seventh mystery."

"He said he did the Six mystery on the video, not the seven. You wonder about it too, Lucie."

I never talked about this part of the video to them, I never said that he specified Six mysteries.

"How did you know about it Silv?"

"The game isn't over yet, there is still a seventh mystery."

Everyone seems scared of Silv suddenly, she's clearly not acting like usual.

"We finished anyway, it's not important anymore."

"We need to investigate until the end."

"Silv, thy are scaring myself..."

"It's okay Iris, everything will be fine."

"How do you know it will? There are unsolved mysteries left."

"There's multiple?"

Silv looks so serious, the girl that once was joyful is now acting strangely. Is it because her father left?

"The seventh mystery left aside, why did Dr. Kilt wanted you to remember?"

I don't know the answer yet, it's still a mystery it's true.

"Maybe he wanted me to know the truth?"

"You have a bad memory, Lucie. He said "If that was my choice, you would have never learned the truth. But something convinced me otherwise." What convinced him?"

"How can I know, he already left. And how can you remember what was in the video? Have you seen it before?"

"You have a bad memory, but you're not totally dumb. I have seen the video before, I searched a lot in my father's stuff before."

"When have seen it?"

"When he made it, I actually asked him to do it."

I can't believe what I'm hearing. The reason Kilt did all of that was because she asked it?

"You are the "something" that convinced him?"

An evil smile appears on her face, it's really creepy to see this smile on Silv's face.

"I was, but the mystery isn't over yet."

Sofia marked "why did you do tat?" on her notebook.

"You'll need to think about it later, right now I want to know about the next mystery. Why did he agree? He had no reason, he even left the hospital out of fear."

"Because he loves his daughter and would do everything she asks?"

"He doesn't care for me at all. Tell me, what reasons would lead someone to do something they don't want?"

"There are multiples, threatening, blackmailing, guilt."

"In our case, what would be the most logical? It can't be guilt, since I had to ask."

"We're talking about your father, don't you think it's going too far?"

"Please tell me it's a joke, Silv, please." Owen seems really desperate, he can't believe it either.

"Nobody said that when he did these things to me. Play the game Lucie."

"If I had to guess, it would be blackmailing. You probably knew a lot of things he wanted to hide."

"Bingo, you're a great detective, Lucie. He hasn't even told everything he did, only I know."

"Know what?"

"You'll need to guess detective. I'll give you an information he left out, he probably thought it wasn't important. He hasn't erased your memories, only locked them. For Five years they were locked. After these five years, if anything made you remember the past, you would slowly remember."

"But, how is it relevant?"

"After these Five, your body would remember Yuki and you'd be able to see her."

"But if everything happened Ten years ago, then why haven't I seen Yuki after these five years?"

"There's a problem with Yuki's memories, she forgot everything in those Ten years, aside from these last few days, and what happened before her death."

"How do you know all of that?"

"My father noted a lot of things, even after the experiment was over. Then, why have you never seen Yuki these last five years?"

If Yuki can't remember, it will be hard to know.

"The only thing I can think of is that she never came near me during those Five years."

"Exactly, you haven't seen each other these Five years. It's probably because she was tied up in the basement for almost a decade."

"How could she be? People that can't see her can't interact with her."

"Then what does it mean?"

I can't believe it, but it's the only explanation. 

"That someone else can see her?

Silv's smile get even more creepy.

"Yes, and who's the person that can see Yuki?"

"You?"

"Correct! Well I can't see, but I can feel her."

"Silv, has thy known everything since the beginning?"

"I knew everything since I was 8, I planned that moment so much. It's so exciting."

"You tied up Yuki in the basement? Just so I never see her and remember?"

"Yes, I needed to have a group that would investigate for me. It's not fun to have a story with Three characters, and I couldn't risk the fact that you would remember alone. I wanted a real mystery!"

"But why did you do that?"

"I told you before, I even asked Kilt to warn you."

I remember Kilt said to be careful of Silv. She asked him to do that? Is she the sole reason everything is happening? 

"I remember Kilt warning me to be careful of you, but I still don't know why."

"Chapter 4, I told you I wanted to be the main character. I did all of this to have my own story to tell!"

Chapter 4? Main character?

"Are you crazy Silv?"

"Yes I am. I am ever since what happened Ten years ago."

"What happened?"

"Think Lucie! It's a mystery after all! I'll give you a hint. As you know, I can see Yuki. Why?"

The only other one that can is me, because of the soul link, that would mean that.

"Your soul is linked too?"

She claps with her hands, she looks very satisfied.

"You know that a lot of people had their soul linked to Yuki, But your mental health was very bad. He tried something in secret, a new experience. Since Yuki wasn't enough to heal your trauma, he linked your soul to the only available person. If I wasn't here, maybe your body wouldn't have been able to recover from the trauma, and you would have been in the same state as Yuki."

"He used his own daughter?"

I can't help but shake, was Kilt ready to go that far?

"But this time it was a one way link, since I was healthy, he thought my body could endure everything. It was a one way link, when he saw what it did to me, he had to link my soul to Yuki's to save me. You robbed me of my sanity Lucie, so now let's solve the seventh mystery together. The mystery of the Three girls that killed someone Ten years ago!"

"You were with us ten years ago?"

"I was only once, he would always lock me in my room. But I escaped, and we played together, now let's solve the mystery!"

This was supposed to be a normal day, we would all have fun. But instead the true mastermind behind the mysteries revealed herself. Silv, the blind girl passionate of art, is the true reason everything happened.
