Raimei has brown eyes and blonde hair she almost always keeps tied up in two neat pigtails with black ribbons or scrunchies. Her casual clothes typically consist of a striped zipped sweater and a skirt. She caries her sword, Kurogamon, in a cloth sheath slung over her shoulder with a strap, and brings it everywhere with her. She can be seen wearing a number of accessories, most notably a large beaded bracelet on her left wrist.
Raimei is a determined and outgoing girl with a lot of energy who holds tight to her convictions. She does not hold back in expressing her emotions. Like Miharu, she has a devilish side which she uses from time to time to get her way. She cares very deeply and passionately for the people important to her, willing to do whatever she deems necessary and in her power for their sakes, and places a lot of pride in the name of her family.
Raimei's tendency to mistake one person for another (and in one case, a dog) comes from being lost in her own thoughts, and seems to get progressively worse the more she has on her mind, and the more stress she is feeling. It is implied that she has had this problem ever since she lost her family five years ago.
She can also be quite blunt and lacking in filter, revealing information she intended to keep to herself when excited. She can be stubborn and prideful at times, as seen during her first appearance with Miharu, but can be caring and serious when the situation calls for it. She has a deep-rooted anger for her brother due to having a bad memory of him, and this leads to her being cautious and aware when getting close to friends for the first time.
Raimei is a student and a samurai from the Shimizu clan. After the death of her family, she was taken in by the Fuuma and studied in Tokyo, where she at one point studied English under Tobari. When the Shinra Banshou revives, she arrives in Banten intending to assess the new possessor of the secret art as a Shimizu, and ends up deciding to transfer to Banten Middle School to watch over and help Miharu Rokujou, while also hoping to gain leads on the location of her brother, Raikou, so that she can kill him.
Raimei was raised along side her older brother Raikou and was given the sword Kurogamon, the opposing sword to Raikou's Shirogamon, by their mother, Kourin. One night five years ago she found her brother killing their uncle in apparent cold blood, and her parents along with everyone else's bodies lying around him. All she could do was watch in despair as Raikou mentioned that he was going to join the Kairoshu (Grey Wolves). Without knowing what happened on that day or why her brother didn't kill her along with the others, Raimei developed a hatred for Raikou making it easier to push him out of her life. She then has sworn to kill him in revenge.
Years later after Raikou joined Kairoshu, they fought mercilessly after Raimei finally confronted him in a bed of red spider lilies, but the battle ended in Raikou's victory. Having lost the battle with her brother, and her sword, Kurogamon, left Ramei in the hospital stricken with grief. The two reconciled later and stayed on friendly terms after Raimei learns from Gau that the massacre was Raiko's vengeance against their uncle and his gang, who killed Raikou's and Raimei's parents.
Later, after she gets out of the hospital, Raimei goes forward to meet Raikou for a rematch. In the field of Spider Lillies, Raikou gives Kurogamon back, but quickly disarms Raimei anyway. Upset, Raimei lands a punch on Raikou, yelling at him for thinking her to be so weak and taking on the burden alone. Crying, she asks him to come home. But Raikou tells her that it is too late, and makes her take up her sword once more. When his Brother is about to finish Raimei off, Gau, who in an attempt to intervene, takes Raikou's blow, the one meant for Raimei, saying "I came to accept my punishment." Gau then falls over bleeding, and instead of being angry, he begs for the two to stop fighting, and apologizes for breaking his promise not to tell Raimei as he slips under into comatose. This deeply distresses Raikou, his concern for Gau's condition runs so deep that he contemplates whether Gau will awaken or not, believing that he will not, due to thinking that Gau no longer wanted to see him again.
