Characters / If My Heart Had Wings

Main Characters

Aoi Minase

Voiced by: Kazuyuki Okitsu (SNOW PRESENTS drama CD)

---

• Affectionate Nickname: Hotaru calls him "Ao-nii."
• Chaste Hero: Zig-Zagged. In Kotori's route, he treats the heroine much like a knight would a princess by his own admission. In Amane and Ageha's routes (especially the latter), however, he's far from hesitant to leer at them, and is quick to rush into sex in the latter.
• Chick Magnet: Aoi has girls asking (indirectly) for his number the first day he shows up, has multiple love interests getting attached to him quickly and has first year girls trying to flirt with him later.
• Childhood Friends: With Tatsuya, Masatsugu, Ageha and Hotaru.
• Depending on the Writer: The lasting effects of his leg injury depend on the route. In Kotori's, there are no lasting effects to his going all out. In Hotaru's in FLIGHT DIARY, an awkward landing flares up the old injury and puts him out of commission for a week. In others, he mentions that he can still ride his bike but only casually.
• Ephebophile: Subverted. Aoi romancing Yoru and Asa is perfectly fine because they are actually fifteen. It doesn't stop Ageha and Kotori from accusing him of being one, however.
• Establishing Character Moment: Rushing into the bath to save Kotori from drowning after she insisted on not needing any help. Also one of the few rare instances where a hero is not accused of being a pervert or having ulterior motives by either Kotori or Kanako after it happens.
• Foil: To Kotori. Both have had their lives dramatically changed by a physically traumatic accident that kept them from doing something they love. However, while Aoi handles this by bottling up his emotions and putting up a friendly face for those around him, Kotori stubbornly isolates herself from her peers and (at first) is gratuitously cruel to those around her.
• The Heart: Being a Nice Guy who tries to do his best for everyone and make them get along, Aoi tends to be the center of the group.
• Manic Pixie Dream Girl: Gender inverted. Aoi is bright and friendly, if perhaps nervous around girls, and helps the sullen and temperamental Kotori to open.
• Nice Guy: Aoi is quiet, mellow and tends to act as the emotional core of the group with his supportive personality.
• Oblivious to Love: Aoi is pretty poor at picking up on the feelings of girls. He doesn't notice the first year girls that like him, is blind to Ageha and completely overlooks Kotori. To be fair, though, Kotori is pretty heavily trying not to think about such things.
• In Touch with His Feminine Side: Aoi is quite good at cleaning and cooking and took over managing the Flying Fish Manor dorm after the previous dorm mother was injured.
• Throwing Off the Disability: In Kotori's route, he uses his bike to catch up to Kotori's father's car and suffers no lasting effects other than tiring out.
• Twice Shy: Kotori and Aoi both admit they like each other to Ageha, but to her frustration they dance around the issue forever despite their clear intimacy.
• Unwanted Harem: While on most routes Aoi's interest in one girl is clear and the others don't pursue him on Ageha's route, circumstances lead to Aoi looking as if he's into several other girls while he's actually only after Ageha. He is teased mercilessly over this, with Hotaru claiming to be "number one girl in Aoi's harem."

Kotori Habane

Voiced by: Airi Sakuno

• A-Cup Angst: Kotori has glimpses of this in relation to the other girls, as notable during the club's trip to the beach.
• Aloof Dark-Haired Girl: Invoked: this is how she wants to be seen. However, not only is she too emotional, but she also lacks dignity and has a reputation as a crybaby.
• Art Shift: She's the only one to get new portraits in the epilogue route of FLIGHT DIARY to both show her as two years older and standing upright when using her cane. However, whenever she's again using her wheelchair in that route, the art returns to her original, younger self.
• Big Sister Worship: While most of the time she is exasperated by her overly-affectionate big sister, Kotori nonetheless brags about Hibari's accomplishments.
• Break the Haughty: A good portion of her Character Development begins after she refuses to accept any help in taking a bath and nearly drowns as a result.
• Call of the Wild Blue Yonder: Even more than the other Soaring Club members. Even being disabled in a ballooning accident did nothing to dampen her love of the sky.
  Kotori: The qualification [for new members] will depend on whether they are in love with the sky or not! It's unfortunate, but I won't recognize people who aren't our comrades.
  Ageha: You're the only one who feels that way.
  Aoi: That's right. Don't lump us together like this, it's embarrassing.
• Character Development: Kotori goes from asocial jerkass to tsundere to timid and even putting others ahead of herself.
• Digging Yourself Deeper: Kotori tries to claim she's a cool beauty, but mispronounces the word and then tries to backpedal, even going so far as begging for a reintroduction. All she manages to do is absolutely destroy the dignified, rich girl atmosphere she had presented during their first meeting.
• Disability as an Excuse for Jerkassery: Kotori can get away with a lot since people are concerned about her. Nobody else would be able to get the leeway she does socially. Later, after she mellows, even she admits herself that she was pretty insufferable.
• Don't You Dare Pity Me!: Kotori has some issues along this line, but for the most part she avoids the subject and even knows she's exaggerating what people are thinking.
• Genki Girl: Post time-skip Kotori is very cheerful and fun loving.
• Heroic BSoD: She spends a good deal of the epilogue route of FLIGHT DIARY in a funk over graduating and it gets even worse when her not paying attention during a flight causes the glider to stall, endangering herself and Haruka.
• I Hate Past Me: She comes to find her insufferable attitudes, both before her accident and before bonding with the Soaring Club, to be really embarrassing.
• Innocently Insensitive: When Kotori opens up a little bit, she still doesn't really know how she should be treating people if she doesn't want them to hate her and can still end up being on the rude side.
• The Matchmaker: Plays matchmaker for Amane and Aoi.
• Meaningful Name: Her name contains the kanji for "bird," and she's always believed that to be the catalyst for her love of the sky and desire to fly.
• Once Done, Never Forgotten: She wants Aoi to completely forget about her "cool beauty" mishap, but he says it's too-fond and funny a memory to ever forget and loves teasing her about it.
• Proud Beauty: Subverted. Despite her "cool beauty" mishap, she privately thinks her legs make her unattractive and is very self-conscious. She was a straight example before her accident.
• Shipper on Deck: For Aoi and Amane in the latter's route.
• Throwing Off the Disability: Subverted. Her route in the original VN is the only one where she decides to undergo surgery to regain her ability to walk and it takes at least a year of rehab afterwards to get as far as just taking a few steps with a cane. In the epilogue route of FLIGHT DIARY, she's gotten much better when using a cane but still has to rely on her wheelchair quite a bit.
• Took a Level in Cheerfulness: She starts as a somber and aloof girl considered unapproachable by everyone around her, but after joining the Soaring Club she becomes far more cheerful and upbeat.
• Tsundere: Kotori is the defrosting ice queen type of tsundere for the most part, but even after that she's still not very honest with her feelings.
• Tragically Disabled Love Interest: Kotori lost the use of her legs in a balloon accident two years ago. The resulting social problems made her move to another school and at the start of the story she's about to drop out of that one too. She's also a little lonely since she used to be popular before the accident since she assumes that nobody will look at her like that anymore.
• Twice Shy: Kotori and Aoi both admit they like each other to Ageha, but to her frustration they dance around the issue forever despite their clear intimacy.
• Wacky Marriage Proposal: The epilogue path of FLIGHT DIARY is a continuation of her route with a few events from Amane's thrown in, ending with Aoi proposing to her in the middle of their final flight.

Ageha Himegi

Voiced by: Jun Miruno

• Affectionate Nickname: Her little sister Hotaru forgoes Japanese Sibling Terminology and just calls her "A-chan."
• Cannot Spit It Out: She's unable to answer Aoi's confession, seemingly out of embarrassment. In reality, it's because right after he confessed to her in their childhood, the "secret hideout" in which she hung out with all of her friends got demolished, and everyone disappeared from her life. After he returned, and they found a new place to gather, that place was also destroyed. She blames herself for all of these things. As a result, she is afraid to fall in love. She finally says it while dazed after sex, but later claims it doesn't count since she was essentially a different person. The rest of the route involves her continuing not to say it while teasing him in various ways.
• The Charmer: Most apparent in her own route. For most of her route, she is not directly working on the glider with the rest of the Soaring Club. Instead, she uses her way with people to network with at least 5 other school clubs and outside specialized suppliers for equipment and support. In this way, she gathers key weather data on the Morning Glory, equipment and resources to build the glider.
• Childhood Friend Romance: She was one of Aoi's friends during his younger days, and she has a fairly obvious crush on him, so they enter this during her route.
• Demoted to Extra: She only has her own route in the original game.
• Dude Magnet: On the other side of things, Ageha is noted to be very, very popular with boys. The other girls are emphasized as being cute as well, but Ageha is the one that gets the most attention. This is presumably due to her friendly, outgoing personality.
• Guile Hero: Most apparent in her own route. She is astute and observant in her dealings with others; able to quickly make friends and strike bargains by herself to gain valuable resources, data and support to build the new glider. At the same time, she even plans camouflage operations to disguise the Soaring Club's activities and movements in and out of school. Most notable is getting the support of the Touring Club for their specialized equipment and mechanical know-how, up-to and including drag-race cars! Said cars become critical to launching the glider when they are prevented from using the winch.
• Gratuitous English: Ageha is a frequent offender, with lines such as "Ranwe izu kuria!" ("Runway is clear!")
• Making Love in All the Wrong Places: Once on a beach in the middle of the day and once on a grassy hill in the evening.
• The Matchmaker: Plays matchmaker for Kotori and Aoi in Kotori's route.
• Nice Girl: Ageha is noted to be very friendly and popular despite being a little tomboyish.
• One of the Boys: Ageha was apparently really boyish when she was younger. When Aoi told her that, she resolved to be more girly.
• Overcome with Desire: How all 3 of her sexual encounters with Aoi begin. The first time starts when they get soaked by a sudden downpour just outside the dock where they keep the glider. They run inside and Aoi can't take his eyes off Ageha's clingy wet shirt. She suggests stripping and hang the clothes to dry and that's that. The second encounter is similar, except they're on the beach of a lake. The third starts when they find themselves alone in the dock inspecting the glider. Conscious of one another, they drift closer and closer together until they give in to their desire.
• Rose-Haired Sweetie: Her hair is a little darker than normal for the trope, but Ageha is definitely the most outgoing, energetic and passionate of the girls on the surface at least.
• Sexy Soaked Shirt: Thanks to a sudden downpour, her wet uniform triggers her first time with Aoi.
• She Is All Grown Up: Ageha used to be rather boyish, so now that she’s girly and cute Aoi is quite surprised and tries to deny admitting it.
• Shipper on Deck: For Aoi and Kotori early on and particularly if Kotori's route is chosen.
• Unrequited Love Switcheroo: Aoi confessed to Ageha when they were younger, but she turned him down. During the main story, she clearly has a crush on him while he has no particular attraction to her (except on her own route, naturally).
• Wrench Wench: Ageha is basically the chief engineer for the Soaring Club and was one of the stars of the Robotics Club before that.

Amane Mochizuki

Voiced by: Ryōko Ono

• Big Eater: Amane eats rather a lot of food, which isn't helped by the fact that she Forgets to Eat regularly, causing her to consume huge amounts of food when she realizes she hasn’t eaten in days.
• Broken Pedestal: The way Amane eats completely shatters Ageha's built-up image of her.
• Buxom Beauty Standard: None of the other heroines even come close to her in bust size, especially in some of the CGs, and most characters tend to think of her as the most attractive member of the cast.
• Caught with Your Pants Down: Twice in Amane's route Aoi accidentally walks in on Amane watching porn, causing him to freak the hell out, and get rather angry the second time as they're dating by that point. Though both times, it's quickly revealed that she's watching for educational purposes, not to masturbate. However, she seems to be pretty into it the second time, at least, and is quite peeved when Aoi demands she stop.
• Cloudcuckoolander: Her ways of thinking are unconventional to say the least, making her appear even more outlandish. When she and Aoi take Tatsuya and Isuka to a haunted house in FLIGHT DIARY she has absolutely zero idea that it's supposed to be scary.
• Cute Clumsy Girl: About the only thing Amane can do with her hands is draw schematics. After the wings snapped on her first test flight, she couldn’t even tell that she had assembled the glider clumsily, so Ageha takes over when it comes to construction.
• Ditzy Genius: Amane is brilliant, but she's also incredibly clumsy, slow paced, forgets to eat and is building a glider despite being afraid of heights.
• Forgets to Eat: Amane gets so wrapped up in her work that she frequently forgets to eat for days at a time.
• Heroic Self-Deprecation: Amane proudly states that she’s an idiot on occasion. She’s actually pleased that she has no common sense since it helps her feel less superior and distant from everyone else. She shows little pride or even notice of her invention
• Improbable Age: Amane manages to be both improbably old and improbably young at the same time.
  • First, she's improbably old for a change of pace from the normal. Namely, she's made the school repeat her several times and is thus in her early-to-mid 20s yet still apparently a high school student. Or something similar, anyway, since the school is a 5-year institute.^note Probably a "kōtō senmon gakkō", i.e. "college of technology", which starts in the same year as a regular high school.
  • On the other hand, she's already a wealthy and accomplished inventor with a lot of respect. Whenever club funds run out, she finances the project with her own money with a clear attitude of spending inconsequential amounts of money.
• Informed Attractiveness: Amane is considered the most beautiful of the girls in the club. Kotori and Ageha are sure that they couldn't compete with her for Aoi if she wanted him.
• Innocently Insensitive: When interviewed on TV about why she designed a new type of wheelchair in the epilogue route of FLIGHT DIARY, she outright states the inspiration came from Kotori (naming her by name) constantly complaining about her butt getting sweaty while in her wheelchair.
• Intelligence Equals Isolation: Before meeting Isuka and being told that she was dumb for thinking there was a single right answer for everything, Amane lived in a socially isolated world that she describes as completely colorless and dull.
• Jabba Table Manners: Some of the CG images in FLIGHT DIARY showcase her actually eating and they are nothing less than this.
• Lonely at the Top: Amane hasn’t the slightest idea how to get along with people and didn’t have a single friend until high school.
• Oh, Crap!: Her reaction when Isuka calls her out on not being consistent with how long she and Aoi have actually been dating in FLIGHT DIARY.
• One of the Kids: Amane is somewhere in her middle 20s but poorly socialized. As a result, her maturity is often outshone by the likes of Aoi, something that eventually comes to bother her a little. After Asa and Yoru join, she's noted to be twice their age.
• O.O.C. Is Serious Business: In the Prologue Route of FLIGHT DIARY, which is also a continuation of her original route, she quietly tells Kotori that she'll stop working on the blueprints that would allow her to fly without needing her legs if she dared tell Isuka about the "year-long imaginary boyfriend incident."
• Promise Me You Won't X: In FLIGHT DIARY, Isuka catches her inconsistent story on how long she and Aoi have actually been dating. Amane tells her she'll come clean only if Isuka promises not to laugh. Isuka does.
• Student/Teacher Romance: Her route technically becomes this between her and Aoi when she starts teaching at his school. Nothing is made of this however, likely because she's only a guest lecturer and Aoi isn't even in her classes.
• Thinks Like a Romance Novel: How the all-ages version handles her Caught with Your Pants Down situations in her route. She spends too much time watching romance movies and requests Aoi to do some ridiculous things based on them.
• Unkempt Beauty: Amane takes almost no care of her appearance and sleeps at a desk rather than a bed, but despite that she's viewed by the rest of the girls as easily being the most attractive.

Asa Kazato

Voiced by: Ai Fukada

• Big Little Brother: Though they're pretty much physically identical, everyone notes that Asa definitely seems like the younger sister compared to the mature, composed and protective Yoru.
• Covert Pervert: Asa appears to be nothing but wholesome sweetness however on her own route she is the one who ultimately jumps Aoi their first time and she proves to be very eager to repeat the experience as often as possible. She also has no hesitation in starting a joint relationship with Aoi along with her sister on Yoru's route nor in having sex with him at the same time.
• The Cutie: Asa tends to be much cutesier than her sister and is subsequently significantly more popular than her, having both more friends and more suitors. It's one of the few things she can actually beat Yoru in, which is helped by Yoru's asocial nature.
• Demoted to Extra: She only has her own route in the original game.
• Different as Night and Day: Fittingly, the twins are named Asa and Yoru, or Morning and Night. Go on, guess what their personalities are like. They also always have different values and like different things. Apart from Aoi, that is.
• Lethal Chef: Asa is completely hopeless when it comes to cooking. She buys the wrong ingredients and tries to wash vegetables with detergent. After that much, people tend to step in to stop things from getting even worse. During the twins' route, she improves quickly. It's hinted that she never really tried to learn how to do it properly
• Like Brother and Sister: Subverted. Aoi says that Asa is sort of like a little sister, which she takes literally. He really just meant that he’s protective of her.
• Not So Above It All: She can be as devious and snarky as her sister under the right circumstances, especially when the two of them have shared "evil grin," sprites.
• Red Oni, Blue Oni: Being passionate, friendly, caring, and a little ditzy, she is the red to Yoru's blue. She sometimes wears a red skirt, just in case you didn't get it.
• You Are Better Than You Think You Are: She's given this talk in the epilogue route of FLIGHT DIARY when Kotori names her her successor as leader of the Soaring Club.

Yoru Kazato

Voiced by: Hatsumi Takada

• The Ace: Yoru is almost as smart as Amane, athletic and has a lot of people that want to be her friend. However, she is somewhat socially withdrawn because she doesn't see any tangible value in interacting with others even when she knows she's lonely.
• Always Someone Better: When Yoru is told that Amane is even smarter than she is, she scoffs and dismisses the idea. When Amane is shown to be genuinely more intelligent, she ruefully admits she's been bested for the first time in her life. In a different route she even gets irritated after she loses despite claiming she didn't care who won beforehand.
• Demoted to Extra: She already had to more less share a route with her sister in the original game, but at least it focused on her. In all other games, she's just a side character.
• Didn't Think This Through: To get back at Asa for going to her club meeting instead of hanging out with her, Yoru steals her favorite underwear, puts it on and sends a picture to Asa, forgetting that Aoi and the other club members would be there to see it as well when the picture arrived. Oops.
• Different as Night and Day: Fittingly, the twins are named Asa and Yoru, or Morning and Night. Go on, guess what their personalities are like. They also always have different values and like different things. Apart from Aoi, that is.
• Dismotivation: Yoru tries not to do too much better than Asa. For example, she can read her sister perfectly and thus predict what she'll do in any round of rock paper scissors, but will instead always throw out the same hand since to lose is annoying and to win would make her sister sad.
• Hidden Depths: In her route, she reveals already having obtained a pilot's license and is the one to reach the Morning Glory with Asa after Aoi is injured.
• Intelligence Equals Isolation: If she can't see the material value in doing something, she won't do it. This leaves her pretty lonely, though she doesn't fully realize it.
• Jerk with a Heart of Gold: Yoru is grumpy and sarcastic, but she also cares a lot for her sister and always goes out of her way to take care of her.
• Lonely at the Top: Rejects the companionship of people apart from her sister.
• Red Oni, Blue Oni: Being cool, aloof, and brilliant, she is the blue to Asa's red. She sometimes wears a blue skirt, just in case you didn't get it.
• Sugar-and-Ice Personality: Yoru likes to act cool and distant in contrast to her sister, but really loves her sister and would do anything for her. Later, she also begins opening up to Aoi as well.

Supporting Characters

Tatsuya Igarashi

Voiced by: Akito Sakuragi

• Big Brother Worship: He's not really their big brother, but all of his childhood friends (Aoi, Ageha, Masatsugu, and Hotaru) look up to him in this way. This is the root of their referring to him as "An-chan."
  • Big Brother Instinct: He returns the attitude, constantly taking care of his younger friends like an older sibling and even tells Aoi in one route that he wishes they really were brothers.
• Chick Magnet: Tatsuya is rather popular with girls, especially ones older than him. It apparently increases in age until elderly women are fawning all over him.

Masatsugu Tasaki

Voiced by: Yūichi Iguchi

• Hopeless Suitor: After his girlfriend Eri breaks up with him off-screen, Ma-bou goes for Akari, but she's both unimpressed and already likes Aoi.
• Flat Character: Of all of Aoi's childhood friends, he gets the least screen time, and never gets a day in the lime light.
• Hidden Depths: In the epilogue route of FLIGHT DIARY it's revealed he succeeded Akari as student council president and is just as helpful towards the Soaring Club as she was.
• I Want My Beloved to Be Happy: Despite having a thing for Akari after breaking up with his first girlfriend, he steps aside and stops trying to win her over after learning she likes Aoi in her route.
• In-Series Nickname: Aoi, Ageha, and Tatsuya call him "Ma-bou," whilst Hotaru calls him "Ma-kun."
• Red Oni, Blue Oni: The red to Aoi's blue.
• Tsundere: He's enough of a blatant, cliché tsundere for Aoi that Kotori wonders if he might be competition.

Hibari Habane

Voiced by: Tae Okajima

• Cool Big Sis: She is Kotori's older sister, and she shows nothing but warm affection for her. A little too much, according to said little sister.
• Nice Girl: In contrast to Kotori, Hibari is quite friendly, if a little to clingy to her beloved sister.
• O.O.C. Is Serious Business: She has a serious OOC moment upon seeing Kotori exit the glider after her first flight and even slaps her. It's revealed she witnessed the accident that left Kotori paralyzed and is deahtly afraid of a repeat if Kotori ever flies again.
• Omniglot: Aoi is amazed when Kotori pretty much brags about Hibari's ability to speak German, Spanish, English, and Swedish, in addition to her native Japanese. It's quite useful, as her job makes her go overseas, no matter how much Hibari doesn't want to stray far from her sister.

Hotaru Himegi

Voiced by: Tomoko Nakamura

• Ascended Extra: She gets her own route in FLIGHT DIARY in place of her sister Ageha.
• It's All My Fault: Her route in FLIGHT DIARY begins with her taking the blame for accidentally aggravating Aoi's knee injury and moving into the dorm to take care of him.
• Love Triangle: Hotaru has a crush on Aoi like her sister, but you can see her early on clearly refusing to even risk getting in the way by joining the Soaring Club. Later in Ageha's route, competition with Hotaru is the thing that genuinely makes Ageha nervous rather than Amane or Kanako.
• The Nicknamer: As noted in the above characters' nickname sections, Hotaru does not use the real names for any of her Childhood Friends, nor any form of Japanese Sibling Terminology for her sister.
• Red Oni, Blue Oni: The blue to Ageha's red.
• Romantic False Lead: On Ageha's route. She has a pretty strong crush on Aoi and at one point, frustrated by Ageha's refusal to commit to anything beyond a sexual relationship, Aoi goes on a date with her. It gets as far as Hotaru offering sex before Aoi realizes he loves Ageha too much to go through with it.
• Sixth Ranger: As the youngest of Aoi's group of childhood friends, she was too young to get involved in the gang's more reckless exploits. So instead, she ended up just tagging along.
• Stalker with a Crush: Gets dangerously close to this in Ageha's route, constantly popping out of Aoi's shadow and declaring quite openly her intent to steal him from her sister. At one point she rolls around in his bed because it smells like him.
• Yamato Nadeshiko: She's a bit too insecure to fully play this role, but her polite, serene, feminine nature is one part of her personality that sticks out.

Akari Kumoi

Voiced by: Airi Yoshida

• Ascended Extra: Whilst a side-character in all other releases, she has a route in the additional story of CRUISE SIGN alongside Kotori, Amane, and Kanako.
• Beneath the Mask: Her route reveals that, outside of her role in the student council, she lacks confidence in herself, is completely inexperienced when it comes to romance, and feels like she has not yet found a real goal in life.
• Cannot Spit It Out: Subverted. Despite being almost cripplingly shy when it comes to romance, she's one of the few heroines to confess to Aoi first in her route and it catches the reader off guard as much as it does Aoi.
• Cloudcuckoolander's Minder: She's hired as Amane's personal assistant to basically keep her from running away all the time in the epilogue path of FLIGHT DIARY. In other routes, she isn't officially hired but still assists Amane in her teaching duties.
• Easily Forgiven: None of the Soaring Club members blame her for Tobioka's actions in her route, despite her expecting them to crucify her for accidentally being responsible (primarily due to Tobioka lying to her more than anything she did).
• Heroic BSoD: Gets hit hard in her route after learning Tobioka lied to her about making peace with the Soaring Club followed by him threatening her student council position by saying he could claim favoritism due to her dating Aoi if she filed a complaint with the teachers. Her guilt is so strong she locks herself away for several days and falls off of Aoi's radar, feeling she doesn't deserve to speak with him.
• I Have This Friend: She tries to pull this twice in her added route and almost immediately blows it both times.
• Indirect Kiss: After Aoi accidentally drinks from her soda bottle, she quickly musters up the courage to drink from it again, using that momentum to confess to him afterwards in her route.
• Not What It Looks Like: This happens early in her route when she falls when climbing out of the glider and lands on top of Aoi. Made worse when Ageha and Kotori enter the room before they can get back up.
• Reasonable Authority Figure: Akari is initially somewhat antagonistic by nearly disbanding the Soaring Club, but she's just doing her job when other Club Stubs aren't being recognized and don't take up nearly the amount of space. When they get more members, she is perfectly willing to help them out and stand up for them to the best of her ability.
• Shut Up, Hannibal!: In the climax of her route, she openly calls out Tobioka and his literal mob of teachers for blatantly abusing their authority to antagonize the Soaring Club after their attempt to halt the takeoff on the day of the Morning Glory nearly results in Aoi and Kotori not safely making it off the ground and crashing into the lake.
• Student Council President: Akari, eventually. While initially antagonistic, for most of the story she's firmly on the side of the club and uses her position to assist them as best she can.
• Sugar-and-Ice Personality: Akari is a bit cold and distant, but she's only trying to do her job and once she sees that the club is doing activities properly she even helps a little. She even develops a little crush on Aoi early on.

Kanako Shigure

Voiced by: Saki Nakajima

• Ascended Extra: She gets routes in both FLIGHT DIARY and CRUISE SIGN.
• Beneath the Mask: Kanako acts all friendly and flirty, but she actually keeps almost everyone at a distance and doesn't like getting involved with their plans or their problems. A little bit into her route she slips up and accidentally plays peacekeeper when Yoru and Asa start fighting. Afterward, she feels meddlesome until Aoi thanks her.
• Big Eater: Kanako is the only one of the girls at Aoi's dorm who can eat all the food he cooks, no matter what it is. For the rest, there's too much, which isn't helped by the fact that it isn't very visually interesting.
• Can't Act Perverted Toward a Love Interest: After Aoi sees Kanako nearly naked, she stops walking around the dorm wearing only her underwear.
• Cool Big Sis: Kanako does her best to make Asa and Yoru feel at home in the dorm and even compares herself to their big sister.
• Lethal Chef: Even when Kanako tries to cook a simple dish for a sick person, she ends up burning it and somehow making it salty and spicy. Well, the spiciness is probably to be expected given that she tried adding in Tabasco sauce. Later, she tries copying what she saw Aoi doing. We can see the disaster slowly unfold as it becomes clear that Kanako is both too inventive and inattentive. It actually does end up almost edible, though, prompting Aoi to help her cook something that's actually quite good.
• Shameless Fanservice Girl: Kanako wanders around in her underwear when it gets hot, which makes a lot of people uncomfortable. After her mother remarried some guy with a son approximately Kanako's own age, her mother made her live in the dorms since she refused to stop wandering around the house half dressed.
• The Tease: Kanako really likes flirting with Aoi since she knows he’s too straightlaced to do anything. There are a few hints in the twins’ routes that she might be more serious about it than she acts, or at least might actually like him.
• Unwitting Instigator of Doom: Played with as her ideas trigger the catalysts for conflict in a few routes. In Amane's, she's the one who suggests searching the internet for dating advice leading Aoi to walk in on her watching porn. And, in the lead in to the twins' routes, it was her idea to do the Twin Switch that led to Asa's misunderstanding how Aoi felt about her.

Isuka Misagi

Voiced by: Rika Kasuga

• Attention Whore: Isuka always wanted to be the center of attention, though unlike Ma-bou she at least wanted others to think she was great or interesting.
• Book Dumb: Isuka had a lot more common sense than Amane, but was noted to not be terribly bright. This really helped their relationship since with the common sense Amane lacked she could help her feel less isolated, while Amane respected her common sense a great deal and helped her feel smarter in return.
• Girliness Upgrade: Downplayed but present. During her and Amane's school days Isuka wore her hair fairly short and is always seen in her school uniform. Once she returns in Amane's route her hair is now very long and she's wearing summery dresses.
• Heroic BSoD: Played for Laughs in the prologue route of FLIGHT DIARY when she gets so overloaded by Tatsuya's confession, she can only cry out in adorable panic and run away. When she comes to her senses, hours later, she panics again upon remembering it all and rushes to Amane for advice- after needing even more time to calm down again.
• Manic Pixie Dream Girl: To Amane in a platonic sense. Her desires and wishes shook up Amane's life. It was Isuka's desire to see the sky that roped Amane into re-founding the Soaring Club, fixing the glider and seeking the Morning Glory, even long after Isuka herself disappeared.
• Posthumous Character: Subverted. The early half of the story states she disappears after the glider was found wrecked by Amane and Tatsuya. Thus the modern Soaring Club members fear this trope was played straight. However, she left Kazegaura for treatment of her crash injuries and her generally ill health. Keifuu Academy covered the whole affair up, leaving even Amane and Tatsuya in the dark.
• Take Up My Sword: She takes up the dream of flight when she found the old Soaring Club's glider, flight log, and their picture of the Morning Glory cloud. Inspired by the photograph, she persuades Amane to restart the Soaring Club and gets Tatsuya to join them. Before her disappearance she hides the log in her room at Flying Fish Manor. This allows the room's next inhabitant, Kotori, to take up her dream and see it through.
• The Glasses Gotta Go: Isuka thought Amane looked much better without glasses, so she stole them, hid them and made her use contacts instead. In the present, Amane is still under the impression that she just lost her glasses and continues wearing contacts.
• Why Did It Have to Be Snakes?: She is utterly terrified of ghosts and the idea of the supernatural, as the group learns when visiting a haunted house during the double date in FLIGHT DIARY.

Hat

Voiced by: Kayo Nakata

• Riddle for the Ages: Both where he got the hat and why/how he keeps wearing it is never explained or even really addressed... until the Prologue Route of FLIGHT DIARY reveals that it belonged to a doll that Isuka liked but Hat destroyed. After burying the doll (under the dorm's floorboards), she gave its hat to Hat.
• Nearly Normal Animal: While Hat generally behaves as one would expect a tame duck to he occasionally seem capable of taking orders a duck really shouldn't understand. Examples include Kotori ordering him to attack her sister and Aoi using him as a wingman with Kotori.
• Team Pet: Of the residents of Flying Fish Manor.

Kujira Tobioka

Voiced by: Tetsuya Oka

• Did Not Think This Through: His claim to opposition against the Soaring Club is because flying is dangerous, but he ends up becoming directly responsible for endangering the club members even more so as a result of his actions in several routes.
• Jerkass: He apparently has a grudge against Amane for almost making the Robotics Club a national icon, but screwing up at the last second and abandoning the club shortly after. Since then the Robotics Club, while popular, has failed to recapture the glory it had when Amane was part of it. Because of this, he's spent years trying to dismantle the Soaring Club, and interferes with its events.
• Heel Realization: Has one in Amane's route when he realizes that trying to destroy the glider is simply going too far and finally gives Isuka's letter to Amane after holding onto it (and hiding it from her) for years.
• Oh, Crap!: Even he realizes the danger that Aoi and Kotori are in in Akari's route when the chock securing the plane comes loose and the wind threatens to blow the glider into the lake. Unfortunately, the teachers with him are in "frenzied mob" mode and don't hear his calls to calm down and secure the glider, forcing the emergency takeoff.
• Smug Snake: Has this attitude in Akari's route because he thinks he can use the fact that Akari is dating Aoi as leverage to shut down the Soaring Club after lying to her face that he had made peace with them.
