御門 龍水

A stepdaughter of Ryuumei and the heir of the Mikado House. She has an arranged marriage with Madara Yakou. Despite the fact that the marriage is arranged, she loves and respects her fiance. From childhood, when she was adopted, she was put through rigorous training to be a proper head of the house. One of the most significant aspects of the training is onmyoujutsu. She has the ability to look into the future in a matter of seconds, giving her an advantage in critical situations. Ryuusui took part in the Fencing Kagura ceremony. It is because of her future prediction that she was able to survive Mibu Soujirou's surprise strike. Only a few techniques were used by her—enemies' strikes were faster than chanting. After Sakagami Habaki arrived, she stopped fighting. It was arranged that she would participate in the Eastern Expedition. She is an energetic young lady with a strong will. She is more hardworking than talented. The fact that her physique appears young and lacks feminine charms is something she is bothered about. Sometimes individuals, including Habaki, refer to her as a shortie. It makes her throw a tantrum. Her main aspiration is to become worthy of her mother, Ryuumei, and spouse, Yakou. Ryuusui regards herself as blessed. Everything is turning out the way she wants it to. This is the truth, which she had not questioned before the Eastern Expedition. All the characters in her story should be ideal. And the story should be happy for her. Those are something akin to rules.In reality, this is the form of her distortion that she is unaware of. It changes the world to her liking. Because of it, she was adopted by Ryuumei. Because of it, she has unwittingly created Madara Yakou, an exceptional man in any area. Because of it, she was able to meet with her mother even after her death. It is she who, thanks to her distortion, revived Yakou after his defeat by Hajun.
