Raimeiki manifests as lightning surrounding the blade. Her true form is revealed to be that of a young woman with sharp slanted eyes, a black horn protruding from her forehead, and long unkempt hair that is held down by a black wide headband that sits behind her horn with some strands sticking out. As a former vampire, she has pointed ears and fangs, which adds to her wild looking appearance.
Her outfit is the most revealing of the demons so far with her top being covered by two black cloth strips that are wide in the middle to cover her breasts and thins out at the ends to be tied around her upper arms near the shoulders and down to her stomach. She wears a black mini skirt that is also tied behind her back, a long matching scarf and arm length fingerless gloves, and her legs are covered past her knees in what looks like shadow.
Raimeiki loves taunting and mocking Kureto as a possession-type demon. She takes pleasure in when she tells him to abandon all responsibilities and give into his greed and desires, often telling him about his lust for Aoi Sangū. She also easily gives up as shown when she was telling him to stop the sealing of Shikama Dōji; tricking him into needing more greed and desires. When Kureto succeeded, she was amused, telling him to keep going. Oddly Raimeiki also never told Kureto about her abilities other than basic electricity.
However, she also stated that she was desperately trying to protect Kureto from Shikama Dōji by sealing him, which shows her having some level of concern for Kureto.
Raimeiki's past is unknown except that she was a vampire and Shikama Dōji knew her. After becoming a demon, she got sealed and cursed inside a katana at some point, and formed a contract with Kureto Hīragi to become his cursed gear. He uses Raimeiki even in the light novels, this means that it was his primarily weapon since he didn't use any other cursed gear.
Events of 2015 Edit
When Kureto interrogates Guren if Mahiru is possessing him or not, Kureto gives Guren a syringe to control his own demon, however Guren's arm refused to do so forcing Kureto to inject it. Though it didn't work, Kureto summons Raimeiki wanting information and asks her if Guren is lost, she tells Kureto he don't want him to be so, and Kureto asks if the experiment was a failure, making her wonder if she knows. Kureto tells Raimeiki then he will have no choice but to kill him, however she remarks that isn't what he wants to do, Kureto states that it's not what he wants but it's to choose the right path. Raimeiki laughs at him when he is being honest to himself but he doesn't want to express it, she calls him a coward but yet strong. Kureto asks her to give him strength but she cuts him, explaining that the drug is working also complains about how demons and their masters disengage as she can feel demon's presences even right now. After Kureto questions Guren if he is himself again, though he conforms so, but Raimeiki tells Kureto it's not him but the drug is working but his demon has the upper hand. The possessed Guren silences Raimeiki. After a while, the possessed Guren and Kureto stopped talking, Raimeiki tells Kureto that the possessed Guren did sound naughty. Ignored, Raimeiki stays silent and later Kureto returns the sword to it's sheath.
When Kureto started to begin a speech about the birth of the Japanese Imperial Demon Army and it's orders. He draws Raimeiki and shoots a bolt of lightning into the sky, as is it a single column of electricity that pierced the night to bring everyone attention.
Events of 2020Edit
During Kureto's interrogation on Yūichirō Hyakuya, the former uses Raimeiki to attack and overwhelm Yu.
Osaka Arc Edit
Shikama Dōji greets Raimeiki as a long time friend when Kureto uses the blade to stab the six-winged demon. After getting possessed by Shikama, Kureto meets with Raimeiki in his mind. The demon confirms that Shikama was the First Progenitor of the vampires, but when asked about his greeting to her, Raimeiki ponders it for a moment before telling Kureto that she doesn't remember. Raimeiki then reminds Kureto that demons seek human greed and desires as they are unable to retain memories of their previous lives, and brings up Kureto's lust for Aoi and his desire to abandon all of his responsibilities. She also states that those desires are the exact reason he is so drawn to Guren and jealous of Mahiru which has Kureto question her loyalty. She tells Kureto that she is on his side, and though his father told him to never trust anyone, she says that he should trust her right now because she is desperately trying to protect him.
Raimeiki then disappears into shadowy smoke and sees the real Raimeiki, struggling to keep a set of double doors on the floor shut. She greets Kureto, explaining that he was talking with a shadow of her, and assures him that who he is seeing is the real her. Raimeiki explains that Shikama Dōji is trying to open a door into his heart, and upon seeing two chains escape through, she uses lightning to repel them.
Currently Raimeiki is holding off Shikama Doji from invading Kureto's mind and body but according to Kureto she can't hold him forever due to him being stronger than her. When Kureto was later handcuffed he promotes being apathetic strengthens Raimeiki by holding off Shikama Doji more. When he laughed at Yu idiotic actions Shinya stated this also strengthens Raimeiki as well.
