Asuka Kurashina (倉科 明日香 Kurashina Asuka?) is the main heroine of the Aokana: Four Rhythm Across the Blue visual novel game and the main protagonist of the anime series. She is a transfer student who transfers into Masaya's class. She is the current all-Japan Flying Circus Fall tournament champion.


Asuka is a beautiful young teenage girl with long, straight, flowing baby-pink hair which reaches down to her hips, and has a small piece of hair tied into a ponytail at the side with a blue wing-ribbon (which is later revealed to be a one of the wing parts of Zephyrion action figure given by Masaya), and she also has a ahoge pointing up. Asuka has blue eyes and fair skin, and she is usually seen in a normal Kunahama Academy uniform, which consists of a of a white short sleeved shirt, a sailor-like blue collar and a red ribbon hanging from it,and a navy blue-colored skirt which her shirt tucks into. She also wears brown general Grav-shoes, which she was clueless as to how to use at first.

In her Flying Suit, Asuka wears a suit that covers her entire body except her shoulders. The suite is white but it is pink on various areas; on the collar, on her chest, stomach and legs. She also wears white gloves and white/pink competitive grav-shoes.

Otherwise, Asuka wears normal clothes, mostly a white dress.


Asuka is an all-natural girl who prefers to fly in straight on. She is also kind, cheerful, energetic and honest and has it easy to make friends. She loves and admires Zephyrion. She always talk politely, no matter who she talks to. She is diligent and brimming with curiosity. And once she set her mind to a goal, she'll give it her all to achieve it. At times, she can also be somewhat air-headed, childish and clumsy, but she is also mature and can stay calm under pressure. She is also clever during matches, and uses her abilities to her advantage. As to that, during competitions, Asuka is neither a sore loser, nor one to hold grudges. When she loses, she'll politely congratulate the winner.



Asuka as a child.

As a child, Asuka wished she had the ability to fly, as she sings "Oh you are so weak, but you can fly." Asuka had visited the Four Islands Archipelago as a child because of her dad, but lived elsewhere because of her father's job.


When Asuka was young she visited Kunashima a few times. When she visited Kunashima, she met a boy (Masaya), she played a lot with him, but when she had to leave, he gave her a present it was a part of a zepherion wing (as she now uses it as hair piece).

Years later, Asuka is back on the island Kunashima. Coincidentally, she met Masaya Hinata again on her first day of school in Kunahama Academy and befriends him, and meets a girl named Misaki Tobisawa. They then go to the school together, Kunahama Academy. If they were going to be late for school, Misaki suggested to go flying, but Asuka had never flied before with grav-shoes. However, they taught her and they came exactly in time to the classes.

After the class ended, they went outside, and Masaya and Misaki helped Asuka to properly fly. The next day, they were helping Asuka to fly again, and little by little, she became better. They then all go home, and Misaki and Mashiro walks Asuka home. When they were going home, they see a FC battle between Shion Aoyagi and Reiko Satoin. Asuka realized that the Kunahama "in" was in danger, and she challenged Reiko to a FC match, and she then accepted, and their battle started. Asuka was having a hard time while Reiko was getting point after point. Then, Masaya came and took Misaki spot as Second. As advise of Masaya, Asuka was trying to get a point through her back but Reiko dodged the move and Asuka was about to fall in the water but she managed to do a Air Kick Turn, and she scored a point. The match ended with Reiko 20 - Asuka 1, it was Asuka's win.

With Asuka's win, everyone was shocked, Shion was really grateful for what Asuka did, and asked her if she wanted to join the FC club, but she still wasn't sure yet. Shion then he asked Masaya, but they all ran off quickly.

The next day Madoka has asked if they want to join the FC club. Asuka is still unsure, but when the class endend Madoka asked again if she will join the FC club and she agreed. When they are at th FC clubhouse she sees Misaki and Mashiro, who are joining the FC club too. When the training was over Madoka asked if they are free tommorow to buy some FC stuff.

So then the next day they went and buy some Grav Shoes and a Flying Circus Suit, at the store Asuka is hesitating for which type is going, at that moment Minamo Shirase is sugesting she will take the all-rounder type. The next day Misaki wanted to have a match against Asuka, Asuka agreed. When they asked if Aoi want to be Asuka second she suggested that Masaya will be her Second. The match started and Asuka is not going to sollid but it is going better than first. Then Masaya suggested that Asuka is trying to do a Air Kick Turn but it failed... With a very big disapointing result, Asuka is frustated and want to be better, and asked if Masaya will be her coach again, and he agreed. After Masaya agrees Aoi got a call from the Takafuji Power house ask if then can partcipate in the training camp.

When Asaka and the rest are on Takafuji ground, they begun their training. First up is just flying a course, when Asuka is going to fly she stumbled a bit. When the training was over Asuka and the rest of the girls (Misaki, Mashiro, Madoka and Rika) went to a hot spring

after the hot spring they went to eat some food, the next day, they have matched some players to go against each other. Asuka is going against Rika, Mashiro is up against Satoin and Misaki is up against Shindo, they wanted the strongest member to fight against Shindo, but when Shindo walked in he is dissapointed that he is not against Asuka.

Outside the first match started Rika vs Asuka. Then the match started Rika is staring solid, but Asuka has improved since the last time, Asuka is taking a shorcut, but Rika used Scissors to confuse Asuka. It almost ended with 6 -0, but Asuka gets 1 point via a Air Kick Turn. The match ended with Rika 6 - Asuka 1.

All the matched has ended and Asuka is frustated that she didn't do anything good, so she wanted to try even harder from now on.

A few days later, it started to rain so they are practicing inside, so when Misaki is chasing Asuka, Asuka did a backflip, and landed behind Misaki. Everyone was suprised and said that her jumping skills are amazing.

The next day it was still cloudy but they still practiced outside, it seems that Asuka has improved since the last time. When Mashiro saw that she started her secret lessons with Rika. When those secret lessons where over, Mashiro wanted to duel Asuka. Asuka was suprised when she saw that Mashiro has changed. So she motivated herself to become even better and prepare for the summer tournament.

That night they went and eat Mashiro udon, but when Asuka asked what for ingredients are in the udon, Mashiro's Mom said that the secret ingredient is flying fish, when Asuka heared that she is heart-broken, her favorite animal is in the delicious udon. After they have eaten udon Asuka got a mail from her mother but dropped her phone, but then a girl came by and picked up her phone for her.

The all-Japan Flying Circus Summer Tournament West-Kyushu Qualifiers finally begins. Asuka and the rest of the club are very excited, But she saw Mashiro's mother her stand and she thinks about the flying fish and felt heart-broken. Then they went to see who they are up too. Asuka was against Arika Okoze a childhood friend of Mashiro.

They went off and changed in her flying suit, Asuka is hyped, because it is her first time wearing a flying suit. When all the matched are finished Asuka match has begun. It begun with 2 - 0 for Arika, but Asuka used a Air Kick Turn and maked it 2-1. The match ended with 3-2 for Asuka. When the match finished they all went to Asuka, but when they wanted to congratulate Asuka, they see Asuka sleeping. Misaki and Mashiro are helping Asuka to bring her to her bed room. Underway Misaki congratulates Asuka for her first time win.

The next day of the tournament Asuka is facing Kasumi Kurobuchi in the second round, when the time was over Asuka won and moved forward to the next round. As she is watching Misaki is against Shindo, she sees that Misaki has lossed and her next oppenent is Shindo. When they are eating Udon, Asuka is not doing to well, she is tired from her match beforce, When Misaki sees that she takes Asuka to the woman toilet. Misaki is helping Asuka to get ready for the next match, when they heard the announcer said that the next round will be starting, Asuka and Misaki are heading over there.

Then the match against Shindo vs Asuka has begun. But beforce the match started Shindo said he is going to be real this match. The match started and Asuka takes a shortcut, but when she wanted to touch his back, Shindo unleased a move that he hasn't used in the tournamen the Cobra. Everyon was in shcok that he will use it. Asuka takes another shortcut and followed Shindo again but this time she did a Air Kick Turn, but when she did a Air kick Turn shindo used it too. Asuka refused to give up and used a 3 straight Air Kick Turn. The match was almost finished, but then Shindo screamed and scored 2 points. The match ended with Shindo 5 - Asuka 4.

When the match ended against Asuka got a lot of fans around her ask how she did a 3 straight Air Kick Turns. The crowd left and went to go watch Saki Inui vs Kazunari Shindo. When the match ended Asuka thought it was awesome how Saki "battled" against Shindo.

After the tournament they had a day off with the FC club but without Misaki, Asuka dived in the sea, but when she dived she got a jellyfish on her feet. Afther the swimming they went and eat meat on the barbecue, Asuka then begged Masaya on being her coach again.

When they finally meet up again at the Club Room, Madoka came with a letter that says that Misaki left the team, Asuka is in a big shock...

Everyone is schocked why Misaki is leaving, when the next day begun they went to go see Misaki but she said it was just boring. When they followed Misaki and she run away Asuka chased her and Asked why she is leaving. Misaki said that she was scared of flying again.

The next day they heard a helicopter when they are training. They went and go see who is on the helicopter. It was Irina Avalon and Saki Inui asking if Aoi Kagami want to play a match against Saki, but Aoi rufused. But Asuka said she wanted to play against Saki, they approved it. The match started, Asuka is taking a shorcut, but Saki is then using the birdcage which make Shindo loses against Saki. Asuka was not playing to lose so she used a Air kick Turn but she failed and fell in the ocean... Everyone was shocked when they saw Asuka falling in the sea and Misaki came to rescue her. When Asuka is breathing again, she was complety wet and her hands were shaking of fear.

The next day Asuka didn't come to school. Misaki and Mashiro where nice to bring Asuka her some school stuf. The next day Asuka came to school and thanked them for bringing her the stuff. At the training Asuka didn't do well its was like day one when she started. Masaya then suggested to take a day off. At night Asuka is watching Zesphrion, while thinking about her past when she met a guy at the island, she played alot with him but then Asuka had to leave so she can't play with him anymore.

The next day Asuka is at a lighttower but then Misaki came to bring her lunch which she forgot to take from the classroom. Then Asuka ask why Misaki left the club Misaki said that she can't fly anymore, when Asuka heard that she made her decision. She is taking a break from the FC club, when Madoka saw the paper from Asuka said that she is taking a break shocked het whole group. Mashiro texted Misaki a message that Asuka is taking a break and it now where to be found Misaki is shocked at was planning to search for Asuka but then saw her in front of her house wet.

When they are in Misaki's house Mashiro came too, to see how Asuka is doing. When they are finishing eating dinner Misaki is saying that Mashiro has to leave so she can talk with Asuka. When Mashiro leaves Misaki is asking why Asuka takes a break from the team. Asuka said then that she can't fly anymore, but Misaki then encouraged Asuka and that motivated her. Then Asuka is sleeping with Misaki.

When Misaki, Mashiro and Asuka are going to school they are almost going to be too late, like day 1. But then Asuka stopped midway, and said that she want a match against Misaki, to find the answer: because the answer is in the sky.

Madoka and Masaya are shocked when they see Asuka and Misaki perparing for a battle. Masaya wondering why Misaki is flying again, Misaki said then if Asuka is going to win she will be returning to the club. The match started Misaki and Asuka are having fun batteling each other, but Misaki won the match against Asuka and Misaki returned to the FC club.

The next few days they were pracicing for the Fall Tournament.

The following day Asuka was practicing early, when the rest of the team came they where suprised how early Asuka came. A few minutes later they heard a voice and that was from Satoin, and Rika, Asuka asked them if they wanted to come to practice together.

During there practice Asuka did a 3 vs 1 against Rika, Mashiro and Satoin. It was to help to doge the opponent.

After that Asuka sprained her arm and went to the shop to get some medicines for her arm. On the way home she saw a cat and walked towards it. But then she saw Saki watching over the cat and Asuka told that she is training hard to put a better match against her. Saki said that that is impossible.

The next day Shindo came (Misaki called him) and helped him with their practice but during the practice Masaya interupted the practice match of Misaki and Shindo. Masaya said then that Asuka had to take a point from Masaya, Asuka tried but it was too hard. Later Aoi-sensei interupted their match and said that all of them shall try to take a point.

Few days later the Fall Tournament begun, Asuka and Misaki are cheering for Mashiro. Who is up against Rika. When the match ended Asuka is overjoyed when Mashiro won. Later that day they go and eat Mashiro Udon, and Asuka's match was right after that and she won. The day ended when they go home they saw a helicopter when they are try looking who is in there they saw Irina and Saki.

The next day Asuka has her match against Mayu, she has won the match and goes to the finals. She rushed over to watch Misaki's match against Saki. But unfortunately Misaki has lose and Saki is advencing to the finals and Asuka oppenent is Saki for the finals.

So after a few hours the match between Asuka and Saki are beginning. Asuka is really excited to face Saki. When they are ready to face each other Asuka said that she is going to do her best to put a better battle than beforce.

The match started and Asuka is using 3 straight sonic boost to get the first buoy. Next she is using Pentagram Force to confuse Saki and get another point from her. Next Saki want to get her revenge and tries to touch Asuka but Asuka is dodging every single move. It is going further and then Asuka is going to do a super low yo yo and gets another point. Irina is getting a little mad because Saki is not doing well and said that Saki should release her balancer. Saki released her balancer and gets all the points to get the points even. Next Saki is using green sleeves to drain away all Asuka's energy. But then the time is over and they will have a little break and after that over-time will start.

Asuka is sitting on the ground and is really exhausted, but Asuka said that this match is fun and said that she wanted to release her balancer too. But Masaya and the rest said that is ridicilous. Only Misaki is on her side and said that Asuka can handle it and that we should trust her.

The over-time is over and Saki and Asuka are returing to the field. Asuka is struggeling to fly straight but it is not going to well she is going straight to the water and dived in the water. But then all the water splashed away and her Grav Shoes wings go bigger. She went straight for the buoy and the second buoy but Saki was straight behind her but Asuka used then a 3 Straight Soni Boost again. Asuka said then to enjoy this match but Saki doesn't know how and Asuka is showing her the scores where even and they both went straight in the air, and because they are flying circles the contrails they are leaving is staring to become a big pink/green ball.

The over-time was over and the person who scores a point now wins the game, but Asuka lost control and Saki was almost going ot touch her but she managed to control her grav shoes again and she touched Saki from behind and won the match.

Asuka came back and Misaki ran toward her and congratz her for becoming champion.
