- Alliterative Name: Kagami Kusakabe.
- Early-Bird Cameo: She appears during Ikki's bout with Stella in the anime's first episode.
- Idiot Hair: She has a couple of hair strands sticking out from the top of her head.
- Intrepid Reporter: She is always seeking out stories and data about up-and-coming Blazers, to the point where she made the novels' stat sheets.
- Self-Duplication: How her Blazer ability works, and it's not just limited to herself, but her Noble Art, "Raise Up", can also multiply the effects of other Noble Arts as well.
- She Knows Too Much: She's knocked out and tied up by Alice when she discovers the identities of all the Akatsuki members.
- Smart People Wear Glasses: It shows how she manages to create the stat sheets out-of-universe.
- Stealth Expert: She is heavily implied to be one, especially when she witnesses Ikki's non-tournament duel with Kuraudo without being noticed by anyone.
- Achilles' Heel: His "Area Invisibility" only makes him and his arrows invisible to the naked eye, so if his opponents uses AoE attacks with an added Splash Damage, he's basically screwed. Also, if his opponents are keen enough, they can sense his position as well.
- Aesop Amnesia: In volume 17, he's shown to not changed his fatalistic outlook after his defeat, and only sees Ikki's victories as the latter being lucky rather than skilled.
- Ain't Too Proud to Beg: Was in literal tears just moments before Ikki slashed at him.
- Always Second Best: Due to his over-reliance on his Noble Art, he'll never amount to Ikki, a fact that Stella acknowledges to Shizuya. Both fall under Crippling Overspecialization, but Ikki uses his head to overcome his weaknesses while Shizuya shuts down the moment his invisibility fails him.
- Antagonist Abilities: Invisibility, Stealth Expert, Improbable Aiming Skills, and Long-Range Fighter. The perfect counter to Ikki's melee fighting style.
- Archer Archetype: Shizuya fits the bill, but is an antagonist rather than an ally.
- Barbaric Bully: He's Ikki primary tormenter at Hagun Academy. Not only did he have Ikki hospitalized during the latter's first year, but he manages to mock him in their duel towards the end of volume 1.
- The Bus Came Back: He hasn't made an appearance since the first volume, but has reappeared sixteen volumes later where he's been training for an upcoming rematch against Ikki..
- Casting Gag: He's ironically voiced by Yoshitsugu Matsuoka, who's usually typecast into Nice Guy Harem Genre roles.
- Cheaters Never Prosper: He was initially a crowd-favorite and everyone knows that he cheats, especially Ikki.
- Chick Magnet: Until the ending of his duel with Ikki.
- Combat Pragmatist: He takes full advantage of his long-range Device and his ability to become transparent to take down his melee orientated opponents.
- Confusion Fu: With the ability to become invisible and having the advantage of range to hit his opponents at unexpected angles makes Shizuya a formidable foe.
- Crippling Overspecialization: While "Area Invisibility" and the use of his weapon, Oborotsuki, gives him an advantage against opponents like Ikki, Kirihara can be located if the opponent either uses wide-area attacks or are keen enough to sense his position. As a long-range fighter, he is also helpless against those who specialize in close-range attacks.
- Cruel Mercy: Downplayed in that the teachers probably would have healed him regardless if he was dealt a fatal injury, but Ikki chooses not to injure him at all with his winning blow, instead just barely grazing his nose to make him faint from the horror in front of the school. This ends up humiliating Kirihara more than if he did receive an injury.
- Dirty Coward: Acts brave and "heroic" while he has the absolute advantage, and sadistically brutalized Ikki. However, the moment Ikki could fight back and had a chance of beating him, he breaks down and begs for mercy.
- Dramatic Irony: He relishes in inflicting pain onto others, but can't stand to endure pain himself.
- Early-Bird Cameo: He appears during the first episode of the anime watching the battle between Ikki and Stella.
- Evil Redhead: He has red hair and he isn't the nicest person.
- Faux Affably Evil: Kirihara tries to be this trope, but he lacks the self-control to feign kindness for long periods. He claims he's a Friendly Rival to Ikki, but he can't keep up the facade for more than a few sentences before insulting his supposed "friend."
- Fatal Flaw: His overconfidence causes him to lose his duel with Ikki.
- Green Thumb: The anime gives him the ability to summon a forest, which gives him more vantage points.
- Hate Sink: His constant humiliation and violence towards Ikki are supposed to make Stella and the readers/viewers cheer for the protagonist when he finally wins.
- Hoist by His Own Petard: His Noble Art against Ikki and creating a stir in their duel by having the audience chanting Ikki's nickname ends up causing Stella's inevitable Anguished Declaration of Love. Ikki uses this as his Heroic Second Wind to finally defeat Kirihara and crush his overconfidence.
- Hypocrite: He mocks Ikki for forfeiting against him last year, though he did the same against an opponent in the Sword Art festival. He also calls Ikki a coward for being "afraid" of fighting him but is soon begging for mercy as the latter was able to counter against all of his arrows.
- Invisibility: His overall Blazer ability; especially his Noble Art, Area Invisibility, grants this not only to Kirihara but also to his arrows as well.
- Jerkass: Not only is he a jerk to Ikki, but he also tries to slander Stella by claiming her match with Ikki was fixed. Stella doesn't like Kirihara personally when she first meets him.
- Karma Houdini Warranty: After getting away with tormenting and beating the crap out of Ikki in their Selection Match, Kirihara gets his first major comeuppance when Ikki overpowers him at the end of said match.
- Kick the Son of a Bitch: He delivers an epic Curb-Stomp Battle towards Kirihara at the end of volume 1.
- Laser-Guided Karma: Kirihara's loss to Ikki at the end of volume 1 as it revealed to everyone his true cowardly nature, which also cost him his Girl Posse.
- Long-Range Fighter: Kirihara's fighting style is mainly composed of being completely invisible to his opponents, and shooting them with magic arrows from any direction.
- Names to Run Away from Really Fast: The Hunter is a very scary name.
- Nice Job Fixing It, Villain!: His mockery of Ikki for being "The Worst One" during their duel ends up causing Stella's Shut Up, Hannibal! and Ikki's Heroic Second Wind.
- No-Holds-Barred Beatdown: Delivers one to Ikki, in front of a room full of teachers when the latter was forbidden from fighting back, for fear of expulsion. The teachers in question gave him detention for putting Ikki in the hospital.
- Oh, Crap!: When Ikki has his Heroic Second Wind and gains the upper hand against him.
- It's Personal: In Volume 17, he intends to fight Ikki again after the events of their Selection Match.
- Psycho for Hire: Downplayed in that he's not an assassin, but he was hired by the Kurogane clan to obstruct Ikki. Given his attitude, it's unlikely that he needed anyone to tell him to torment Ikki anyways.
- Rain of Arrows: His "Million Rain" attack causes one arrow to explode into many. It's taken Up to Eleven when Kagami multiplies it up to ten times.
- Red Right Hand: A meta example. While all of the character stat sheets show a complete illustration of those it presents, Kirihara's the only one that presents him as a crude sketch, which is obvious that he's not a good person.
- Slasher Smile: Gives a disturbing one as he continues to torment Ikki in their battle.
- Smug Snake: He gets extremely cocky around Ikki, having qualified as a Hagun Academy representative for the Seven Star Sword Art Festival the previous year, and claiming Ikki ran away from him during a fight. Ikki later clarifies to Stella that he simply chose not to fight back. Doing so would have given the previous director an excuse to expel him, due to pressure from his family not wanting him to be there at all.
- Starter Villain: He is the first villain Ikki encounters in Volume 1 as well as the series in general.
- Stealth Expert: What makes Kirihara so terrifying is his Blazer ability to become invisible and that he uses a bow to shoot opponents from a distance makes him the strongest student in his first year.
- Unskilled, but Strong: Downplayed. While Kirihara does have a certain degree of skill in archery to fire his arrows, he mostly relies on the flawless camouflage of his Noble Art to beat his opponents. This gets deconstructed in his fight against Ikki, who the latter manages to see through his invisibility, leading Kirihara practically defenseless as he keeps trying to spam his attacks which Ikki is also able to counter his arrows with ease.
- Villainous Breakdown: He completely breaks down after Ikki gains the advantage.
- Villains Want Mercy: The moment Ikki saw through him, and by extension his techniques, he wastes no time begging for mercy. He outright screams for Ikki not to harm him, to the disgust of his Girl Posse.
- Wake-Up Call Boss: He sets the pace for foes that have an overwhelming advantage against Ikki's pure melee style, to the point where he fared better than the Sword Eater himself.
- Why Don't You Just Shoot Him?: While he does shoot Ikki, he purposefully avoids finishing shots to drag out Ikki's suffering, which screws him over once Ikki regains his composure.

- Boobs of Steel: Like Stella, Ayase is quite stacked and is the heiress to her father's dojo.
- Bokukko: She uses the gentle-masculine Japanese pronoun of "Boku" as opposed to the feminine of "Watashi" or "Atashi" to refer to herself.

- Cheaters Never Prosper: She sets up a rather intricate minefield with her Noble Art and forces Ikki to exhaust Ittou Shura before the match starts. Despite this, she ends up losing not because her cheating got exposed but because her guilt distracts her from fighting properly.

- Beware the Nice Ones: A sweet, loving and kind-hearted mother to orphaned children, and irrefutably the deadliest and most feared warrior of her generation.

Nickname: Scharlach Frau
- Arranged Marriage: Kanata reveals to Ikki in Volume 0 that she is in an arranged marriage, and after her final year at school she'll be wed and likely have to move to her betrothed's home country.
- Taking this into account, her hilariously awkward questions about kissing and the like become Harsher in Hindsight, as Kanata hasn't even learned the name of the guy she's going to marry, much less fallen in love with him. She probably hoped that by asking Ikki (who's in a strong, healthy, and loving relationship) rather detailed questions about his bond with Stella, she could somewhat experience what it means to be in love with someone.
- Extra-ore-dinary: Her Noble Art allows her to use shards of her sword to damage her opponent from the inside.

- Ojou: Kanata was born into a wealthy and influential family, and is expected to take part in ensuring its continued success. Part of the reason she isn't as bitter as she ought to be about her Arranged Marriage is that she knows that her family does a lot to help the people of Japan, and this is her way of contributing to their efforts.
