|“||And I was [the best], everywhere I went.||”|
Kagami Tsurugi (Japanese Dub: ツルギ・カガミ) is a Japanese student at Collège Françoise Dupont introduced in Season 2 of Miraculous: Tales of Ladybug & Cat Noir. She attracts the attention of Adrien Agreste as his fencing rival.
In "Ikari Gozen", after she is made imprisoned by the titular villain, Ladybug gives her the Dragon Miraculous in order to both free her and defeat Ikari Gozen. When the Miraculous is inhabited by Longg, Kagami becomes Ryuko (Japanese Dub: 龍子), a dragon-themed superhero who helps Ladybug and Cat Noir "during particularly difficult missions" in Season 3 
Kagami is a slender, Japanese teenager of average height. She has pale skin, visible freckles, sharp yellow-brown eyes, and short dark blue hair swept to the left with light blue reflections.
Kagami wears a white long-sleeved blazer that has black outlines around the collar, running down across her waist, all the way to the bottom to the hem, cuffs and two black accents on the top of the fastened outer pockets. The blazer has two gold pockets around the waist and each side of the cuffs. On the top right of her chest is an attached logo that is shaped as a reuleaux triangle. The logo includes her family's crest, with the gold sign of Japanese kanji for female (女) fastened on top of green, white and red fabric with a gold outline surrounding the logo. Underneath, she wears a black collared blouse with many gold buttons. Attached to the collar is a red tie with blue parallel lines which intersect with each other.
Kagami wears a red skirt with an asymmetrical texture that has blue and white intersecting vertical and horizontal lines. She wears tight black leggings and a pair of red sneakers with white toecaps, laces, a black logo on the heel counter and black soles. On the ring finger of her right hand, she wears a black ring that has her family's crest, (女) and it has two long outward spikes stretching from the mark.
Riposte's face and skin is silver with red eyes. She has a silver helmet with angular sides and a red circle on the center of the forehead with the Tsurugi crest. Her body outfit is silver armor; a breastplate, pauldrons and tassets while her arms and legs are solid silver, and she wears silver high-heel shoes. Her right hand seems to be or holds a sword-like extension with a triangular guard and a red circle bearing the Tsurugi crest on the center of the guard.
As Oni-Chan, she has wild, pointy, dark hair, and her face is obscured by a white oni's mask, which has protruding tusks. From the forehead protrudes a red horn, with black lines along the bottom. The eyes and mouth are outlined by thick, black lines. She has a white outfit with black tiger-like stripes and her insignia (a black rose with a red horn) on the chest. Red spikes with black spirals don her shoulders and elbows. Her forearms and legs from the knee down are all black. Her hands and feet are red as well. She wields a bokken with a black and white handle with the blade made from thorny vines twisting together.
As Ryuko, she wears a red bodysuit with the image of a black dragon's tail, outlined in yellow, curling from her left leg up to her to her chest. The end of the tail curves around the symbol containing the images that represent the three elements she controls: lightning, air and water. She also has a black collar/turtleneck (where she has her choker), black forearm-length gloves and black legs starting in the middle of her lower legs, both with yellow outlining. On the back of her head, she has four red dragon-like horns with yellow tips with black outlining and, on her back, she has a holder for her sword. On her face, she wears a red mask around her eyes with yellow and black outlining at the base of the sides. Her eyes also become golden with a yellow scleras.
Kagami is a fierce and thoughtful girl who is dedicated to accomplishing any commitment she makes. Likewise, she can be somewhat reluctant and quite stubborn, willing to go out and take risks regardless of what is at stake for her. However, she learns from her mistakes, knowing there are times she isn't the winner. Despite her wits, Kagami has a small habit of jumping to conclusions, as shown when she saw a picture of Adrien and Lila together quickly assuming Lila was the girl he told her about in Frozer.
Kagami is an aggressive fencer that will taunt her opponent during a fight. While she doesn't like to lose due to her competitive nature, she downplays her upset feelings and respects her rivals, not unlike Adrien. She can be quite emotive and rage-prone in spite of her composed exterior.
However, Kagami is a very hospitable person who ironically forms friendships with people after they both approach each other and solve their conflicts, suggesting an understanding side. She comes across as blunt and willing to speak her mind, telling Philippe that she didn't want to take skating lessons multiple times and even speaking for Adrien when asked. This is more evident when she advised Marinette Dupain-Cheng to stop hesitating.
In "Ikari Gozen", Kagami is shown to be a bit lonely as she always wanted friends and she admitted to Ladybug that she doesn't have any. Yet, she was willing to reach out to Marinette in an attempt to be friends with her. However, much like when Adrien started studying at school and making new friends, Kagami, because of Tomoe Tsurugi (her mother), doesn't know much about how to bond with others. This is shown when she tries to befriend Marinette, only resulting in awkward moments, and using an app about how to make friends. These attempts include traditional Japanese friendship tropes such as blood typing, horoscopes, personality compatibility, and a forced smile when attempting to discuss any of them.
Through having friends and being outside of her mother's strict rules, Kagami has started to become more playful and fun-loving and enjoys being disobedient at times as seen in "Heart Hunter". Just like Adrien, now that Kagami has made friends she doesn't want to hurt or lose them. However, she is aware that going after Adrien romantically would hurt Marinette, and that no matter who ends up with him, someone will be heartbroken over it and, thus, isn't willing to let him go, even for the sake of friendship, showing a realistic side. She would still like to be able to date Adrien and stay friends with Marinette at the same time, though.
As Ryuko, she is very capable but a bit of a loner as she tried to defeat Ikari Gozen on her own. However, she learned she can't handle everything on her own. Ryuko is understanding and respectful towards Ladybug, giving up the Dragon Miraculous indefinitely because of the fact that her identity was revealed to Hawk Moth which could lead to her loves ones being in danger, showing her protective and caring side.
However, she is also a little revealing as she told her mother in her akumatized form (and by extension to Hawk Moth) her identity.
As Riposte, she is furiously obsessed with getting a rematch with Adrien and winning it, even if he is in no condition to fight due to his injured ankle, and she considers people that she views as not being good enough fighters as not being worthy, such as Ladybug. Riposte is also arrogant and doesn't have a problem with outright attacking her opponents when they have no chance of defending themselves. However, despite this, she follows Hawk Moth's commands without question, even if they conflict with her own goals.
As Oni-Chan, she is obsessed with tracking down Lila and getting her to renounce Adrien in order to have Adrien be hers.
As a civilian
Kagami is extremely skilled in fencing, both in defensive and offensive movements. She is also very agile, doing several acrobatic feats while dueling. Her prowess is equal or probably superior to Adrien's. Another sword-based sport she is masterful in is kendo, just like her mother. Her mother also personally oversees her kendo practice.
Kagami considers archery a "noble art" alongside fencing, so it is possible she also excels at it, though it has yet to be shown. According to Marinette, she is very smart and observant, something especially seen during the contest in "Ikari Gozen". She is a quick learner as a superheroine.
Kagami is notably skilled in ice skating, proficient enough to do a combination spin, even though she only does it "just for fun".
Ryuko has super enhanced skills, such as speed, agility, and strength, and she is almost invulnerable to physical damage. Her natural ability in wielding a sword is enhanced.
Her superpowers, Wind Dragon, Water Dragon, and a currently unnamed lightning power allow her to transform into air, water, and lightning, respectively. However, once all three elemental transformations are used, she only has five minutes before she detransforms back.
Riposte wields a sword in combat, and as her sword is directly attached to her hand, making it impossible to remove it. She uses the sword to strike at incredible speeds and slice through any material. She can create shock waves with her sword to slice objects from a distance. Also, she is capable of leaping great distances, and she is durable, quickly recovering from having an entire chimney collapse on her.
Besides possessing heightened abilities, like speed, strength and agility, Oni-Chan possesses a sword that can wield powerful red energy. When she touches someone with it, they grow a horn like hers. The horn seemingly works as a cell tower and sends messages to anyone with a mobile phone that is near the person with the horn, allowing her to trade places with the ones who get her messages and continually track said person as a result.
However, it would appear that Oni-Chan doesn't have full control over this power, as she wasn't able to prevent her from trading places with a firefighter when she was about to take Ladybug's Miraculous or trading places with Ladybug who was tied up to a light post. Another effect of the horn is that, when the person afflicted with it lies, the horn grows bigger.
= Gender Unknown
Kagami first meets Adrien when she tries out for a spot in the fencing club. She fences with him and is distraught when she mistakenly believes that she lost, though she keeps her feelings to herself and even shakes his hand. Though Adrien offers her a decisive match, she sadly rejects the offer. However, once akumatized as Riposte, she targets Adrien, wanting a rematch with him at all costs. When she is deakumatized, she befriends him and agrees to eventually have a decisive match.
In "Frozer ", she shows great concern for him when she notices how down he is. When Adrien tells her about his love issues, Kagami advises him to change his target. She accompanies him to the ice rink and after when Adrien tells her that he has decided not to change targets after Frozer's defeat, Kagami respects his wishes but tells him that she'll be waiting for him when he gives up.
In “Animaestro”, Kagami is happy to see Adrien at the movie premiere, but she becomes jealous upon noticing Marinette and Chloé, aware that they both also like Adrien. According to Mrs. Tsurugi, Kagami talks a lot about him. In "Oni-Chan", it is shown that Kagami really has strong feelings for Adrien as she flies into a bitter rage after seeing a photo of Lila kissing Adrien, leading to her akumatization.
In "Ikari Gozen" she was willing to disobey her mother to participate in a contest Adrien was taking part in. In "The Battle of the Miraculous", just like Adrien, Kagami doesn't find the wedding anniversary very interesting. By helping Marinette, they escaped their parents and played a friendly match in the kitchen. Wanting to continue the fun, she, along with her friends, escaped to the roof and had fun in the ball pit until Adrien's bodyguard arrived, but thanks to Marinette's clever thinking, they escaped again, leaving the hotel.
Kagami is unaware of Adrien's double life as Cat Noir. During "Riposte", she is very angry that, along with Ladybug, he's protecting Adrien and an inferior opponent. In "Oni-Chan", she calls the hero inferior to his civilian alter ego and is furious when he compares himself to Adrien. After she is deakumatized, she gladly accepts back the rose he gives her.
As Ryuko, Kagami doesn't at first work along with Cat Noir, but when it results in him being held captive, she apologizes to Ladybug for failing them both, believing that she's not worthy to work alongside him. After being encouraged by Ladybug, she willingly lets herself get captured to save Cat Noir and takes the cat's compliment about being a fast learner. Like Ladybug, he included her in their trademark pound it.
Kagami doesn't know Marinette too well, but when Adrien tells Kagami about her, Kagami says that she hopes to get to know her better. In "Frozer", she advises Marinette to stop hesitating in order to stop slipping on the ice. In "Animaestro", she treats Marinette hostilely due to her crush on Adrien.
During a friendship contest in "Ikari Gozen", Kagami attempts to make friends with Marinette. She finds her weird, seeing Marinette talking to herself, but continues to try. When it results in Marinette leaving and losing the contest, Kagami finds herself not worthy of their friendship, but when she heard Marinette on Kagami's phone with Kagami's mother, she urged her not to say anything. Marinette apologized for letting things slip out and tried to hide her. After saving her mother but not winning the contest, the game made their friendship stronger, Kagami understanding what Adrien said about her. She is glad to have Marinette as a friend, and the two go out together.
In "Heart Hunter", Kagami, Marinette and Adrien escape together from the Bourgeoises' party and have fun until they go to buy ice cream. She doesn't want to make Marinette feel bad if she begins dating Adrien, but her romantic feelings for him are stronger than Kagami's friendship with Marinette. Despite that, she continues to get closer to Marinette and her other friends, as seen in Marinette's Instagram photos.
Like Adrien, she is also unaware of Marinette's double life as Ladybug. As Riposte, she finds her inferior as an opponent. After being deakumatized, she is in awe at the sight of the heroine. As Oni-Chan, she is furious when she tries to stop her from hurting Lila.
As Ryuko, Kagami didn't work with Ladybug at first, but when it results in Cat Noir being held captive, she is able to see the wrong in her actions and apologizes to Ladybug for failing them both, believing that she's not worthy to work alongside them. She is comforted by the heroine and encouraged to try again. Following Ladybug's lead, they are able to save Cat Noir and her mother together. She was included her in their trademark pound it. However, when Ryuko heard that Ladybug can never let her have the Dragon Miraculous again, she believed it was because she had failed, but the heroine says the opposite. Since Hawk Moth knows her identity, it would put her friends and family in danger if she continues to be Ryuko. Kagami retorted about not having many friends but then took Ladybug's advice, believing it's not about having many friends; it's about treasuring the true friendships you do have. In "Battle of the Miraculous", Ryuko follows Ladybug's orders without question and has a brief talk about her feelings towards her friends.
In "Animaestro", it is revealed that Chloé and Kagami hate each other due to the former's crush on Adrien.
Although Lila behaves as if she didn't know who Kagami is by seeing her in one of Adrien's photos, it is likely that she actually knows her, since Lila has Kagami as a contact on her phone. When Kagami sees a picture of Lila kissing Adrien in "Oni-Chan", she flies into a jealous rage towards her, quickly assuming she's the girl Adrien loves. As Oni-Chan, she tries to get Lila to renounce him and constantly pursues and threatens her in order to make her do so.
At first, Kagami is surprised at her presence, unsure of what she is. Kagami does listen to the information she gives but not all of it. During "Heart Hunter", she is happy to see Longg again despite what Ladybug said in their previous encounter.
