In an alternate reality of the universe, one day, out of the blue, bubbles start raining down from
the sky worldwide. They are so large in number that people are amazed at such a phenomenon.
The bubbles didnt turn into water right away and soon surrounded the entirety of the world. Mass
chaos spreads all around and suddenly a mysterious explosion occurs in Tokyo. Hundreds of people were
killed during the explosion which creates a huge bubble that surrounds the entirety of Tokyo.
By the time the bubbles start exploding, the whole city is already submerged in water.
Only large skyscrapers and tall buildings are above water. This whole phenomenon renders
the city unliveable and people start leaving the city in large masses. Only scientists and
researchers enter the city hoping to find the reason behind the strange phenomenon.
However, the researchers also cant point out what exactly had caused the phenomenon to occur,
even after extensive research they are left clueless and they too leave the city. The
government then decides to label Tokyo as a restricted zone for all the people.
Five years later, Tokyo is now a place inhabited by teenagers and orphans and very few researchers.
The teenagers, unlike the researcher, have come here in hope of participating in an illegal game
of parkour called the battlekour. People play this game for the thrill and also the prizes
which are food supplies to last them enough for a week-long stay in a now completely empty Tokyo.
The appearance of the bubble has created several gravitational anomalies
and the participants of battlekour use these anomalies to heighten their parkour abilities.
The game is simple, the participants are divided into two teams, and each must be able to get
from Point A to point B and acquire a flag. The team that reaches the flag first wins. However,
the two locations are several skyscrapers apart and the teams are allowed to use
force to eliminate the other teams by pushing them into the water below. The games are the only
thing that maintains order in Tokyo as almost all the people participate in these games.
Many of the teenagers that live in Tokyo have created teams to participate in the
battlekour games. One such team is Blueblazes a regular participant of the battlekour games,
they are pretty good in the game and almost always reach the finals alongside their rival
team Undertaker. The main reason that they are so good is because of their ace Hibiki who has
the ability to make super large jumps using the bubbles. Hibiki has the ability to use the bubbles
to jump furthest which is an ability that all of the others lack. The blue blazes are extremely
grateful that Hibiki is in their crew. Hibiki, however, is a very reclusive boy and
at the peak of his teenage. The nineteen-year-old boy almost always has a headphone around his ears
and tries to act cool, even without noticing. The team, although grateful for his being with them,
finds it difficult to actually make friends with Hibiki due to his lonely and reclusive behavior.
The blue blazes also have a researcher friend Makoto who watches all of their
matches in order to analyze the anomalies in the gravity field in and around the Tokyo Bubble.
One day, after winning one of the weekly battlekour games, the whole team returns back
to their base and celebrates the victory. However, like always, Hibiki is not among the team members
celebrating, he is outside staring into the Tokyo tower at the center of the city. Makoto comes
outside and tells him to come inside and celebrate with the others. Hibiki, however, doesn’t want
to indulge himself in underage drinking and rowdy behavior. Told you he’s a “cool kid”
He tells Makoto that he can hear a beat coming from the tower. Makoto assures him that there is
nothing but a strange light in the Tokyo Tower, but Hibiki is pretty confident that he can hear
music coming from the tower. Makoto is confused, she thinks Hibiki is making stuff up and warns him
that if he is planning anything funny, she will report him to HQ and they all will be kicked out
of Tokyo for good. Her threats are playful however and she snatches away Hibiki's headset but just
then, Hibiki hears the music again calling for him. Without a second thought, the boy jumps onto
the motor boat below and races to the tower. Hibiki reaches the tower which is in itself the
precise representation of the chaos that has engulfed the entire world. The torn-down tower
however still stands due to the gravitational anomalies and it looks like Hibiki has climbed
the tower before. He starts using his parkour skills to reach the top where the light has been
coming from. As he does so, a small sentient bubble can be seen following him around.
Just as Hibiki jumps high to reach the light, he is distracted by seeing that a
young boy is there already staring at the sky. Hibiki’s hand slips and he falls straight into the
water below, his clothes get stuck in the train below and he is dragged down. The bubble notices
Hibiki drawing and jumps down to his aid. Pretty sure it's useless but it jumps down regardless.
Hibiki is dragged down to the bottom of the city by the train and has almost given up hope,
his struggling breadths fizzle out as bubbles. The bubbles formed by Hibiki’s
final breadth suddenly rise up and surround the sentient bubble that had followed him down.
The bubbles fuse and suddenly create a beautiful young girl, almost of Hibiki’s age. She quickly
rushes to Hibiki and kisses him, giving him her breath, and drags him out of the water.
However, when she tries to check on Hibiki outside of the water Her fingers revert back to
being a bubble. It's almost as if touching Hibiki would turn her back into her bubble form. Shin,
the unofficial authority of the battlekour games and the acting guardian of the children in Tokyo,
arrives the next day and brings Hibiki and the girl back to the Blueblazes’s base.
The girl, obviously being a literal bubble, has a lot of difficulty at first settling
into the human environment. She doesn't know what to do, what to eat. She can’t even speak,
to begin with. All she does is stare at people and follow Hibiki around.
She is pretty amazed and in awe of the human world and makes friends with Makoto as well.
The girl turns out to be quite the parkour expert herself and impresses the whole team with her
skills too. Since the girl has no recollection of who she is and is acting pretty sus,
Hibiki decides to give her a name himself. He names her “Uta” which means song.
The next week’s battlekour match begins but this time the undertaker group is dominant. They have
managed to acquire special boots that use water to propel them to large distances. Since there
are no exact rules to supervise the games they are allowed to basically cheat the game and win.
That night, Makoto decides on the book she wants to read next, Uta stumbles upon the
library. She also chooses the book “ The little mermaid” whose story somehow intrigues her.
Makoto explains to her the story and as they sleep
she also tells her some interesting facts about the universe.
The next day, Uta is almost confident that she is the little mermaid and Hibiki is her
prince. She had somehow learned to speak all of a sudden and perhaps had a deeper meaning to all
of this. But the teenager takes her words too literally and gets flustered and runs away.
Later that day, Hibiki climbs up to a lonely skyscraper, and unknown to him, Uta follows
him as well. At the top of the skyscraper, Hibiki has actually made a garden out of several flowers.
Hibiki notices Uta snooping around and calls her out. He asks her to keep all
of it a secret. Uta is amazed at the first flowers that she had ever seen.
He then reveals the reason why he always wore headphones around his ears.
He had a medical condition that made him scared when he heard too much noise and
even though this was a medical issue even his parents felt disgusted toward him. All his
childhood, he got nothing but contempt from his own mother. Until the day when the bubbles came
crashing down and he remembers hearing a sweet song as if someone was talking to him. When Uta
hears this she suddenly rushes outside and hums the same song that Hibiki had been talking about.
Hibiki is super happy that someone else could also hear the songs of the bubbles.
That night, as Makoto is in her office she realizes that ever since Uta’s appearance
the bubble had been having more and more abnormalities. However, before she can research
further into this the members of the undertaker crew barge into her lab and take her captive.
The whole Blueblazes crew realizes that Makoto is gone. They find out that the undertaker crew had
been illegally streaming the battlekour matches outside of Tokyo calling it the death match of
Tokyo. The gadget they had received earlier was from one of their sponsors. The blue blazes soon
receive a challenge from the undertakers who want them to compete for not only the week’s
rations but also for Makoto whom they have placed atop a large tower alongside the victory flag.
This time around, Uta decides to join the crew as well and the match soon begins. However,
using their gadgets the undertakers lure the whole crew into a pit that they cannot jump across.
Only Uta and Hibiki are able to make the large jumps because of their abilities and
have to maneuver their way through the entire undertaker team. During the process,
however, Uta is forced to hold hands with Hibiki and her hand just fades away.
That night finally Hibiki also participates in the victory celebrations for the very first time.
Everyone is cheerful and happy that everything is well. Uta however is at the top of a skyscraper
staring at the tower before her. She feels like its calling her back to her true form.
Hibiki comes to talk to her and just then the light starts emitting the same bubbles again.
The bubbles start taking over the entire country again just like five years ago.
Uta rushes back to the tower believing that she is the cause of all of this and Hibiki tries to
follow but some mysterious red bubbles prevent him from following her. Hibiki is quickly found
by his teammates and he manages to convince all of them to help him rescue Uta. All of them,
including Shin head to the tower to carry out the parkour. They quickly french the tower but realize
that it had worn down so much that only Hibiki is able to reach the top. There he notices the
same boy he had seen earlier. It was in fact him, or a reflection of him from so long ago.
He realizes that it was from the day the bubbles fell from the sky.
He had heard the song that day as well coming from a bubble. It was Uta. He was the only one who had
heard the song and somehow this had angered the other bubbles which had caused the explosion.
Hibiki then notices Uta conversing with a dark image of herself. She has started to turn back
into her bubble form. Hibiki tries to get to her but the same red bubbles start to surround
and drown him. Uta notices this and jumps to her rescue without even considering that she might
die. She sacrifices herself as she rushes to his aid. As her bubbles separate from her human body
they crush the red bubble and ultimately the entire bubble surrounding Tokyo is broken.
Uta however fades away, before that, however, she finally decides she was
thankful that because of Hibiki she had gotten this physical life and was able to make so many
memories with him and the whole crew. A few weeks have now passed and Tokyo is
now starting to repopulate. The battlekour games however still exist with Hibiki still
being the best at his game with a little bubble still following him around.
