Set in a parallel fantasised world, where a swarm of bubbles rain down the plight of humans on the city of Tokyo, cutting it off from the rest of the world. Apart from the massacre of people, felled buildings, floods when the bubble touches the ground, flashforward into the present day when the deserted city with ravaged buildings and hefty bridges broken and submerged into the floodwater that had not reduced, a group of young orphans whose wild and reckless characteristics arrest the viewers into an intriguing trance, they form a team, Tokyo Battlekour, a parkour game to play given the convenient setting.
Among the young and wild boys, Hibiki is a young man and the protagonist, adept at lunging himself onto buildings and the only one who can jump and bounce off the giant bubbles floating around the place.
Hibiki appears to be distant from the rest of the people, wearing a pair of sound-reducing headsets, maybe a showy saviour who asks others to have fear in them and not just lunge themselves into the open surroundings.
Through the middle of the movie, we discover the secretive aspects of his characteristics, his hypersensitivity to sound, and how he can hear everything to an uncanny level of perfection, which leads him to suspect the forthcoming parade of the bubbles.
The spiralling cycle of human life
Makoto, a researcher among the group, researches this occurrence and tries to find reasons and solutions while tracking the improvement of the boys in this Battlekour, discusses the origin of this planet and given the extreme hazards to human life, despite everything, how survival of the fittest has brought human civilisation to this date, ever-evolving species of animals. Her inept thirst for curiosity and the obsession to quench it made her a prominent character.
The plot unfolds into a chain of mysterious events where Hibiki sets out to the tower that was first ravaged by the bubbles, where a string of red bubbles encircles it in that spiral pattern. He happens to hear a particular melody that he had heard when he was young, and the massacre hit.
During these occurrences, what arrests the audience's rapt attention to every detail of the picture is the beautiful direction by Tetsuro Araki and the beauty of Wit Studios that brought an aesthetic colour to the entire story.
The colour of rage, the colour of loss, the colour of love, regaining confidence and freedom, of retaining peace, everything has a beautiful rhythmic melody that moves the film forward to its ending.
When Hibiki tried in vain to reach the place he wanted to in the tower, he fell back into the sea where the submerged vehicles ran in the wrong direction. The motion had never stopped.
On the brink of his death, when he loses his breath, a bubble takes the form of a mysterious girl who kisses him and saves him from the untimely end. She becomes a part of the battle, but with a fatal flaw in her survival.
Whenever she touched Hibiki, bubbles would form on her skin. Despite the physical warmth, the warmth exuded in their companionship is another beautiful thing in the film.
He names her Uta, given that he heard her song from the bubbles. Both Hibiki and Uta create a beautiful catalytic relationship because Hibiki means echo, and Uta means sound, and both could not sustain without the other.
The eminent ending is a tear-jerker for the audience, as it is oddly similar to the Disney classic, The Little Mermaid, a book that Makoto reads out to Uta, and she could relate to fate of the little mermaid. The latter returns to the sea after saving the prince. When the volcanic red bubbles cause a stir once again, Uta is shown to advance towards it, putting her efforts to stop it from ravaging the city further.
Hibiki runs to her aid. He sees a flashback of the first day that the bubbles showered down, defied gravity, and led everything haywire. He saw that a bubble saved his life, and it was Uta. After rescuing her, he sees that Uta becomes bubbles with his touch and cannot restore her human form.
As they hug for the last timeshare their previous kiss, Uta sees what the human heart is capable of feeling, the love, the loss, the pain of losing someone, and altogether losing her conscience.
Flash forward to the present day after the big massacre, the kids' lives go on as usual. Still, Tokyo has become a part of mainstream society again, without the threat of the gravity-defying bubbles falling again. Hibiki, along with his team Tokyo Battlekour still partake in parkour.
At the same time, the city develops into a happening city with better buildings and fewer submerged houses again. as Hibiki is shown running, a stray bubble is shown to run to him, which the director leaves to the viewer's decision to end the story believing in Uta staying by Hibiki's side in her immortal form.
