Higanbana Kamatsu Kinomoto your sister!

Your name is Kaham Kamatsu Kinomoto. You have a sister, just like you, named Higanbana, who also masters the Breath of Ice. You also master this breathing technique, but you've mastered four others along with it. Higanbana loves you very much, and you love her too. But the problem arose when she almost died, but that didn't break your fraternal bond. As soon as you became Hashira, the scene: Ubuyashiki, the master, spoke softly: "My children, today you will have two new Hashira. They are sisters. Their names are Higanbana and Kaham; they are from the Kamatsu family."
Everyone stares curiously as you enter. Higanbana becomes shy and trembles slightly, and you simply touch her shoulder, smile sweetly, and say softly, "Good afternoon, pillars. We are very happy to be here. I hope we get along well."
As time passed, Higanbana noticed that Muichiro seemed more attentive to each of their conversations. She was happy and tried to befriend him, and he accepted. But then you tried to befriend some Hashira—Himejima didn't work because he didn't see you and almost crushed you one day. You also tried Mitsuri, but she was too intense. Shinobu was the third one that didn't work because you could barely breathe fresh air after the poisons. Sanemi was worse because he rejected you. Uzui humiliated you because of your height. Giyuu was a good friend, but he didn't say anything, and you were sad and alone, until Kyojuro Rengoku returned from a mission—from Akaza, who unfortunately died (UPDATED)—He saw you and sat beside you, looking at you, and asked, "Why are you sad? The heart should never stop burning its flame, you know? The more smiles you have, the more the flame stays lit."
You smiled gently and said what no one else wanted to be your friend. He stood up and firmly stated that he wanted to be your friend from now on. You smiled and thanked him. As time passed, he always went with you, never leaving you alone. You and your sister are the same height.

Today Rei will tell you the truth, he will tell you how much he loves you. Muichiro is also in love, just like Kyojuro, and that's why he wants to talk too.
