Characters from the year 1993
Voiced by: Hikaru Midorikawa (Japanese - game, movie), Daisuke Ono (Japanese - anime), Vic Mignogna (English)
A wanderer traveling across the country in order to find the 'girl in the sky', a goal each generation of his family has passed on for a thousand years. Yukito lives off his trade, a special form of stringless puppeteering that was taught to him by his mother before she died.
- Bishōnen: He looks a lot less generic than most harem leads — though AIR isn't really a harem show in the traditional sense — and even sparkles in the movie.
- Deadpan Snarker: In true Key tradition. He complains about everything from dorky outfits to lack of money, all with a hanging aura of "what is my life".
- Dropped a Bridge on Him: He doesn't die, but as a crow, he has near to no relevance to the plot anymore.
- Identical Grandson: Yukito looks just like what his ancestor Ryuya would look like if he had short hair that wasn't slicked back.
- Out-of-Clothes Experience: A brief glimpse of his human form inside of his crow form reveals this. Justified because birds don't wear clothes.
- Peek-a-Bangs: His hair is like this. One would think it was a way to justify Faceless Protagonist, but he has a face even in the VN.
- Refusal of the Call: When he first realizes that Misuzu is Kanna's reincarnation, like the girl his mother found and couldn't save, he tries to leave her so she can recover because he knows that making bonds with people will hurt her. He later changes his mind, and then calls Haruko out for the exact same thing.
- Street Performer: He tries to make a living as a street performer by making his doll do tricks.
- A Threesome Is Hot: Does not actually occur, but his mind does wander to thoughts of a three-way with Misuzu and Haruko, and also one with Kano and Hijiri. Thank you, special CGs.
The first of the three girls that meets Yukito Kunisaki. She becomes friends with Yukito and invites him to stay over at her house. She is a cheerful, slightly clumsy girl, and often mentions the pseudo-dinosauric phrase "Gao" whenever she feels troubled or is about to cry. Since a young age, Misuzu has had a great love of dinosaurs. She suffers from a mysterious illness that makes her ill whenever she comes to love someone and is loved back.
- All of the Other Reindeer: Misuzu is ignored by her classmates for being out sick so often.
- Captain Ersatz: In Eternal Fighter Zero, fighting style-wise she's pretty similar to Testament, as she's able to place invisible traps on the ground, and sticky traps in the air. She can also summon a crow and command it to attack her opponent, in a similar fashion as Nakoruru.
- Conveniently Seated: She sits in the window seat in the last row of the classroom.
- Cute Clumsy Girl: To the MAX. She practically can't walk five feet without tripping on... well, nothing in particular.
- The Cutie: And she gets thoroughly broken and even killed in the game, movie, and anime.
- Died in Your Arms Tonight: She dies in Haruko's arms.
- The Ditz
- Everything's Better with Dinosaurs: She loves dinosaurs.
- Go Out with a Smile: Misuzu's final smile for her mommy is so heartwarmingly cute that it makes her passing all the more heartbreaking.
- Hair of Gold, Heart of Gold
- Ill Girl: Par for the course for a Key work.
- Important Haircut: Immediately procedes her losing her memory and basically reverting to a childlike state in the anime.
- The Ingenue
- Innocent Blue Eyes
- Lethal Chef: "WAH! A cicada came out of the ventilator! WAH! The soy sauce container fell! WAH! The salad oil spilled! WAH! Yukito-san's bacon and eggs have become something beyond imagination! A-wah-aah..."
- Rapunzel Hair: It's down to her waist at least, and possibly even lower.
- Reincarnation: Of Kanna. They look nothing alike though, unlike many examples of the trope, like Yukito does to Ryuuya. Granted, Misuzu isn't blood related to Kanna, like Yukito is to Ryuuya. Also, it's implied that, thanks to this trope, she might wind up with a happy ending after all, albeit not in her current form.
- Stepford Smiler: To some extent. She acts cheerful, but she's really suffering from a generations-old curse which makes it difficult, even nigh impossible, for her to have close friendships with anyone. After all, whenever she does, unless she distances herself, she essentially is condemned to progressively suffer until her life snuffs out.
- Sunny Sunflower Disposition: She is associated with sunflowers, especially in the official art.
- Too Good for This Sinful Earth
The younger sister of Hijiri Kirishima. Kano is a wily and energetic girl with a cute side, and is always seen with her small dog, Potato. Like Misuzu, Kano has a curse related to the past.
- All of the Other Reindeer: Kano has been teased a lot for wearing a bandanna around her wrist 24/7, talking to animals more than to humans, passing out in class, and just plain being weird.
- Conveniently an Orphan: Her mother was an Ill Girl her whole life and died after complications following Kano's birth, and her father, the previous Dr. Kirishima before Hijiri followed in his path, worked himself to death.
- Demoted to Extra: Literally in the movie. Kano is widely known as the Least Popular Key Haremette despite having her own small fanbase (which calls her Kano-rin).
- Deus Sex Machina: Kano believes that losing her virginity will give her magical powers, thanks to taking Hijiri's effort to rein in Shiraho completely the wrong way.
- Fire, Ice, Lightning: She fights with the three of them in Eternal Fighter Zero, as a reference to an RPG named Ragnarok Online.
- The Gadfly: She's a bit of a troll. Before Yuri came along, Kano was Key's main female example despite nearly every male lead being this.
- Iconic Item: Her bandanna, which she keeps on her person at all times. In her arc in the game, she gives it away, and in the anime, she takes it off and it blows away in the wind.
- I Just Want to Be Special: Wants magical powers. A very heartwarming case of Hilarious in Hindsight, as her wish became true in Eternal Fighter Zero.
- Leitmotif: Mizutamari
- Lethal Chef: In the visual novel. She's only cooked once before because her sister never let her touch the kitchen knives, and when she tries to cook for Yukito, he describes it as "beyond food" and relates it to decomposing bread.
- Magic Wand: Her Weapon of Choice in Eternal Fighter Zero is a fantasy RPG-styled staff.
- Speaks Fluent Animal: Ambiguously.
- You Gotta Have Blue Hair: Her hair is blue.
A top student in the school, Minagi is very quiet and shy. Though she does not hold a spirit from the past like Misuzu or Kano, she is still rather isolated from others. Until she met Yukito, her only friend was Michiru.
- Club President: Of the Astronomy Club, though she is also the only member.
- Demoted to Extra: In the movie, just like Kano.
- Drop the Hammer: In Eternal Fighter Zero, she uses one for her B normal.
- Hair Decorations: Her hair bows.
- Insistent Terminology: Refuses to let anyone but Michiru call her Minagi.
- Moe Couplet: With Michiru.
- Paper Master: In Eternal Fighter Zero, she fights with sheets of paper, whether by throwing them like shurikens, or striking her opponent directly.
- The Quiet One: She doesn't say much.
- Replacement Sibling: Her mother calls her "Michiru" and has erased "Minagi" from her memory.
- The Stoic: She's got the expressive range of a wall.
- Sugar and Ice Personality: Stoic and quiet, but kind.
- Technicolor Eyes
Misuzu's foster mother and aunt.
- Biker Babe: She drives a motorbike.
- Cute Little Fangs
- Drives Like Crazy: She's such a terrible driver, she terrorizes the neighborhood on her motorbike.
- Fond Memories That Could Have Been: Haruko weeps for her adoptive daughter Misuzu to stay alive, bitterly imagining the times she wished she could have spent with her as she dies in her arms.
- Hard-Drinking Party Girl: She's pretty carefree and likes to drink.
- Kansai Regional Accent: She speaks with this accent.
The town doctor and Kano Kirishima's sister and guardian.
- Agent Scully: Hijiri believes that she can't believe in magic or she'd undermine her credibility and reliability as a doctor. She doesn't bring up the subject in front of Kano because she cares more about her sister than the fact that they disagree on this point and it was Hijiri who made Kano's belief in magic so central to her character anyway.
- Hospital Hottie: She's a very pretty doctor.
- Deadly Doctor: She can get intimidating when Kano is involved. However, she only projects this and doesn't actually kill anybody...
- Green Eyes: Like Kano.
- My Sister Is Off-Limits!: With good reason. She knows full well how Kano took her words, and should Kano really attempt to "become an adult" and remove her bandanna, which scientifically-minded Hijiri put on her to trigger her back to her normal self, her "illness" (possession) may actually kill her, as far as Hijiri theorizes. She gets better by the end, where it's no longer an issue.
- Promotion to Parent: She has looked after Kano ever since their mother’s death.
- You Gotta Have Blue Hair: Though it's darker than Kano's and can be taken for black.
An energetic young girl who doesn't seem to have a place to live. Having befriended Minagi at an early age, Michiru doesn't seem to have any other friends. She plays an important role in Minagi's storyline. She enjoys playfully attacking Yukito Kunisaki and has a fondness for bubbles.
- Assist Character: To Minagi in Eternal Fighter Zero.
- Attack Hello: To Yukito every time she sees him.
- Bratty Half-Pint: Mostly towards Yukito.
- Bubble Gun: In Eternal Fighter Zero, she and Minagi use their bubble blowers to strike their opponent, as a reference to her fondness for bubbles.
- But Now I Must Go: Once Minagi is happy and has made other friends, Michiru decides she is no longer needed and then vanishes.
- Fiery Redhead: Okay, her hair's magenta, but she's combative, boisterous, and interested mainly in having fun.
- Full Name Ultimatum: She regularly greets Yukito with a violent "KUUUUNISAKI YUKITOOOOOOOO!".
- Genki Girl: Michiru is bouncy and energetic as all get out, especially when picking fights with Yukito.
- Girlish Pigtails: Wears her hair in pigtails, showing her childish nature.
- Moe Couplet: With Minagi.
- Only Friend: To Minagi.
- Rapunzel Hair: Down to her waist.
- The Reveal: Michiru is actually a wandering spirit who decided to help a lonely girl on Earth after seeing the trapped Winged Maiden. She became a physical manifestation of Minagi's unborn sister to help her through her troubles.
- Stance System: In Eternal Fighter Zero, Minagi can command Michiru to adopt two poses, a "normal" pose for some special attacks, and a "fighting" pose, for enhanced versions of her specials.
- Token Mini-Moe: Not entirely, as she has no route of her own, but she's important enough to the story that she nearly fits the role (unlike, say, Saika).
- You Gotta Have Blue Hair: Her hair is magenta.
- Amplified Animal Aptitude: Potato can do all kinds of things, from juggling to using chopsticks, and when you tell him to "stay", he'll be sitting there all day.
- Edible Theme Naming: With the other Seasonverse mascot animals. Piro is short for "Pirozhki" (pirogi) and Botan for "Botan Nabe" (wild boar stew).
- Pokémon Speak: "Piko!" and occasionally "pikkori!"
- Precious Puppies: He's the game's token Ridiculously Cute Critter, far more cartoonish than his predecessor Piro, who looked like an actual cat and not a walking plushie.
Voiced by: Shinichiro Miki (Japanese game, movie, and drama CDs), Kenjiro Tsuda (Japanese TV series), John Gremillion (English)Misuzu's biological father.
- Chekhov's Gunman: Appears early in the story when Yukito is busking. He's buying a cake for Misuzu's birthday.
- Kansai Regional Accent: Anime only. He speaks standard Japanese in the game.
- Visit by Divorced Dad: Though Haruko is a relative and not an ex, Keisuke's entry into the story looks like just this until you see he's actually trying to take Misuzu back.
A six-year-old girl who meets Yukito when she gets lost. She recurs throughout the series after this.
- Cheerful Child
- Chekhov's Gunman: Saika getting lost seems like a pointless scene, but she becomes a recurring side character after this. While it looks like she's not doing anything important then either, there are implications that she is the last iteration of Kanna, since in the Real Life spirituality that the reincarnation cycle here is based on, already living as a child while your previous self is just about to die isn't out of the question. Oh, and that's her silhouette in the logo.
- Girls Love Stuffed Animals: Often appears carrying the sloth plush Yukito gave her.
Characters from the year 993
One of the last winged beings in history. Kanna was deified out of fear for the awesome power inherent in all of her kind, so from birth, Kanna had been kept in isolated areas away from the general populace. Not long after meeting Ryuuya and Uraha, she escaped with them in order to find her mother. As she traveled with her guardians, Kanna began to develop feelings for Ryuuya, and when the party became surrounded by guards, she took to the sky as a diversion after surrounding Ryuuya and Uraha with a protective shield. While in the air, Buddhist monks cast a spell that bound her into a cycle of eternal reincarnation and suffering that Ryuuya fought to break with Uraha, leaving it up to his descendants to find a way to free Kanna.
- Audible Sharpness: In Eternal Fighter Zero when she attacks with her sword for one of her specials.
- Curtains Match the Window: Blue hair and eyes.
- Dishing Out Dirt: Another of her specials in Eternal Fighter Zero.
- Energy Bow: In Eternal Fighter Zero. Not exactly her bow, but the arrows she fires are electrically charged.
- Godiva Hair: Her hair covers her naked body whenever she strips.
- Heroic Sacrifice: When she, Ryuuya and Uraha became surrounded by guards, she took to the sky as a diversion after surrounding Ryuuya and Uraha with a protective shield. While in the air, Buddhist monks cast a spell that bound her into a cycle of eternal reincarnation and suffering that Ryuuya fought to break with Uraha, leaving it up to his descendants to find a way to free Kanna, a cycle which culminated in his descendant, Yukito, and the girl, Misuzu.
- Innocent Blue Eyes
- Last Kiss: She kisses Ryuuya before her death.
- Last of Her Kind: The last winged being after her mother dies.
- Rapunzel Hair: It reaches her ankles.
- SNK Boss: In Eternal Fighter Zero. Subverted in levels 1 and 2, where she rarely attacks. But from level 3 on she decided to stop playing around, and shows everything she's capable of.
- Too Good for This Sinful Earth
- Tsundere: Like you won't freaking believe. Rather unbecoming of a heavenly being, really.
- Winged Humanoid: As winged being, she has wings.
- You Gotta Have Blue Hair: Her hair is blue.
A skilled, yet low-ranked samurai in charge of Kanna's protection. Unfortunately, after creating a diversion for Ryuuya and Uraha, Kanna was cursed by Buddhist monks to live an endless cycle of reincarnation, suffering, and death. Ryuuya dedicated the remainder of his life to finding a way to lift the curse, and though he never did, he had a child with Uraha in the hopes that their kin would eventually find a way to break the curse. He also received a premonition from Uraha that he was fated to die within the same year as Kanna.
- The Gadfly: He and Uraha love nothing more than teasing Kanna.
- Samurai Ponytail: His hairstyle.
- Your Days Are Numbered: The curse Kanna's mother transfered to Kanna and him makes his wound incurable and he dies the same year as Kanna.
One of the servants in charge of Kanna's care.
- The Gadfly: She and Ryuuya love nothing more than teasing Kanna.
- Rapunzel Hair: Down to her ankles.
- Someone to Remember Him By: An interesting variant. With Kanna gone and Ryuuya soon to follow her into death, Uraha asks him up front to conceive a child with her for this reason - both to pass on their memories and will to save Kanna on to their offspring, and so she'll be left with their child instead of alone after losing both Ryuuya and Kanna.
- Yamato Nadeshiko: Though it isn't explicitly stated, she probably invokes and parodies this trope on purpose.
- You Gotta Have Green Hair: Probably counts as "stylized black" but still has a distinct green tinge.
- Offing the Offspring: She was pushed to do this or let the priests do it for her when she and her child were blamed for misfortune befalling the town. She couldn't do it.
- Unfinished Business: The reason she possesses Kano.
