Kamui: "Hey, Sakura. You're feeling well?"
Sakura: "Umm....Ahh...Y...Yes..."
Kamui: "Huh? We barely spent some time, but could it be that you're not feeling well?"
Sakura: "N...No. My body is doing alright."
Kamui: "So, what is it? Don't tell me you hate me?"
Sakura: "T...That's not it either! You didn't do anything wrong big brother! I..I'm just not used to talking to others face to face..."
Kamui: "Is that so? Sorry for suddenly looking to talk to you."
Sakura: "No. I'm sorry. Big brother struck up a conversation with me."
Kamui: "Well, it's not that major. But, you're right. We're here and all...so, is there anything I can do to have conquer your inability to talk that much?"
Sakura: "Huh...?"
Kamui: "It'll be tough to get to the root of the issue. But if the two of us talk to each other, then you'll get used to it. Sakura will also grasp the ability to talk with others?"
Sakura: "Is that so...?"
Kamui: "Yeah! We won't know until we try it. Let's quickly do it."

B-Rank
Kamui: "So, how is your practice? Are you ready?"
Sakura: "Y...Yes..!"
Kamui: "Well the...AHEM! There is this Byakuya book that I read earlier. I think the history in the first half is dubious. How do I put it. I'm worried that it doesn't do a good job of investigating history."
Sakura: "Is...that so?"
Kamui: "History is interesting. That's right. I think that Sakura became a Miko because she wants to heal others. But, you do have an interest in the history of the gods."
Sakura: "T...That may be..."
Kamui: "In the end, everyone should live on what they give to the gods."
Sakura: "Which one though...?"
Kamui: "......"
Sakura: "......"
Kamui: "Sakura...let's fasten our conversation a bit further."
Sakura: "I'm sorry, brother...I don't know what to say to you...."
Kamui: "Yeah. I think that we should practice having a conversation again and again. But Sakura, rather being bad at talking to others, you're timid when you're front of someone else?
Sakura: "Timid?"
Kamui: "Yeah. You listen to what people say and you want to join in the conversation. But, terror gets in the way first. It feels like it grips your body?"
Sakura: "....."
Kamui: "I think that if we fix your fear a bit, then you'll be able to improve when you talk with others. Sakura..do you know the reason why you're scared?"
Sakura: "......"
Kamui: "There isn't anything you can think of? That may be a clue for us to figure it out."
Sakura: "Umm...I...I don't know."
Kamui: "I see...In that case, so be it."
Sakura: "Of course....I'm sorry...But, thank you for today."
Kamui: "No. It was my pleasure."

A-Rank
Sakura: "Brother....can I have a little time for us to talk?"
Kamui: "Sakura. Of course...but why?"
Sakura: "Umm....It's the reason for why I get so scared."
Kamui: "Something came to mind?"
Sakura: "I'm sorry. The truth is that I knew but I didn't say it then..."
Kamui: "Huh? Is that so?"
Sakura: "Yes. I thought that Brother will take offense to it....So, I promptly lied. I'm so sorry...."
Kamui: "I have no reason to be angry with you, Sakura. So if I can hear about it, then I want to hear it."
Sakura: "Okay...I understand. I was just born when you were taken by the Anya Kingdom...When I grew up, I had Ryouma and the others as my siblings. But, then I was told I had one other brother...But on that day...I heard a rumor among the women within the castle. The truth was that you weren't Anya's target...The truth is that they planned on kidnapping the baby me...."
Kamui: "Huh...!?"
Sakura: "Of course, I knew later that was a rumor that had no basis behind it...But that story was scary to me when I was younger..."
Kamui: "....."
Sakura: "What would have happen to me now if I were kidnapped...You would have been sad, Brother, and not me...I couldn't stand the responsibility. I was scared. I couldn't take it..."
Kamui: "That's not true!!"
Sakura: "....!"
Kamui: "I'm sorry...It's my fault and no one else for scaring you like that. It's because I was taken back then is why you felt like you were responsible...! You wouldn't forgive me even when I apoligize..But, I want to apoligize now."
Sakura: "No....it's not your fault, Brother. But...I was worried about what you would say. So, I remained quiet back then. You're really kind, Brother."
Kamui: "No...That's not..."
Sakura: "I'm sorry....But, the truth is that I was uneasy up until now....If it's possible, you won't go somewhere again, Brother?"
Kamui: "Sakura...Don't worry. I'm not going anywhere. I swear I won't let my precious sister leave my side again. From now on, your brother will continue protecting you."
Sakura: "Brother..."
Kamui: "So, there's no reason for you to be scared. I want you to be at peace..."
Sakura: "I understand. I'm happy. Brother, I feel like I'll become a little bit stronger from now on."

S-Rank
Sakura: "Brother...can I have some time with you right now?"
Kamui: "What's wrong, Sakura? Don't tell me that you once remembered the past."
Sakura: "Yes."
Kamui: "I knew it. I'm sorry that the wound in your heart is still...."
Sakura: "No! I didn't mean it like that!"
Kamui: "Huh...?"
Sakura: "I thought that I had to have courage for what I didn't tell you last time. I...I was certainly scared about that issue with you...At the same time, I always pictured you..."
Kamui: "Pictured...?"
Sakura: "Yes. What kind of person was Brother? Does Brother Ryouma and Takumi love him too? It'd be nice for him to be a kinder brother. If I were to see him someday, will he take a liking to me..."
Kamui: "Sakura..."
Sakura: "I dreamt it too. I was happy when I met you again in my dream."
Kamui: "I see. I'm happy. Have I lived up to your expectations?"
Sakura: "Yes, you have. Rather, more than that. I...took a liking to you the moment I saw you. I took a liking to you as a man."
Kamui: "!! Sakura...That..."
Sakura: "I can't do a good job in telling you this. You are the person I love...So, I was nervous. But if I tell you how I love you, then we won't stop talking like this."
Kamui: "Sakura....I'm really happy that you feel that way. But, we are..."
Sakura: "Yes....Our bond won't allow that. We are siblings who succeded in our father's blood. But if that were the case...?"
Kamui: "What do you mean?"
Sakura: "The day you came back to Byakuya, I received a letter from Mother. I was told to read it if I become worried about being in love with you. I didn't understand then, but Mother has that ability of premonition. She probably sensed that I'd fall in love with you. She wrote that in the letter."
Kamui: "That...?"
Sakura: "You and I aren't a family tied by blood."
Kamui: "Huh!! But, you and Ryouma are...our children of our father, King Sumeragi! If that's the case, we are...."
Sakura: "No, you're wrong....You are not a child of my father. Mother...Queen Mikoto asked him to take in a child from her home when she came to Byakuya. That was you, Brother. Father..knew you weren't his child. But even if it's the child of the woman he loves, then he decided that he'll raise that child like his own. I don't remember Father...But, the depths of his love is certainly true?"
Kamui: "Yes...King Sumeragi....Father truly loved me."
Sakura: "I'm sorry that I was so selfish in telling you something that I shouldn't have. But even so...but I wouldn't have been able to tell you this agin...I want you to see me as a woman."
Kamui: "....Yeah....there's no need to apologize, Sakura. I'm happy that how you truly feel. Besides...I now know we aren't tied by blood. That's a huge shock. But....I'm a little bit happy. After all...I love you too."
Sakura: "Huh...?"
Kamui: "I also feel the same. I love you, Sakura. I wanted to tell you. That's why I made up that excue of practicing having conversations with others..."
Sakura: "Brother...I'm so happy..."
Kamui: "If we're not siblings, then I have no need to keep these feelings locked up. From now on, the two of us will cross whatever obstacles that is in our way. I swear that I will protect you."
Sakura: "Right! I swear I'll protect you too, Brother. So, never leave my side again."
Kamui: "I'm promise."
