On-Gaku: Our Sound

Kenji decides to form a band after witnessing a robbery where a passing musician hands him a guitar to thwart the thief. The instrument becomes his prize, and he brings it to his friends the next day, eager to share his newfound treasure. Though they lack any musical talent, the trioembarks on this journey partly to impress Aya and partly to channel their rebellious energy into something creative.

Earlier, the trio spends their time in lighthearted bullying and idle mischief, showing they lack a constructive outlet for their restlessness.

The Marutake gang, led by Ôba, mistakenly believes that Kenji is orchestrating conflicts against his members. This misunderstanding stems from the chaotic events surrounding Kenji and his friends, leading Ôba to plan a confrontation to teach Kenji a lesson he won't soon forget. The rivalry escalates throughout the film until their final encounter at the festival.

Early in the story, Ota jokingly suggests visiting the rival gang at Marutake High to settle old scores, though they don't actually go.

Kobujutsu is the name Kenji's band chooses, suggested by Asakura as a nod to ancient martial arts. Kobijitsu, on the other hand, is Morita's charming acoustic folk trio. Despite their similar names, the two bands are distinct entities with different styles, Kobujutsu produces chaotic, raw sound while Kobijitsu plays more refined acoustic folk music. The bands eventually collaborate at the festival.

Asakura uncovers the striking musical relationship between their band and Morita's group, hinting at their eventual collaboration.

After Morita invites them to perform at the rock festival, Kenji initially embraces the opportunity but grows disillusioned as practices unfold. The reality of the commitment sets in, and he loses the initial excitement he felt. Despite Aya's attempts to reignite his passion for music, she is unable to sway his indifference, leading to a brief altercation.

The invitation to the festival comes after Kenji experiences Morita's music, temporarily sparking his enthusiasm.

During the festival confrontation with Ôba's gang, Kenji's bass shatters. In a moment of spontaneity, he pulls out a recorder and begins to play, which stuns Ôba's gang into silence as they pursue him. This unexpected switch from electric bass to a simple recorder becomes a pivotal moment that leads to his eventual stage appearance and the collaborative performance.

The tension with Ôba's gang has been building throughout the film, culminating in this dramatic festival showdown.

After Kenji reveals to Aya that the band has dissolved, she is heartbroken. In a surprising moment of casual optimism, Kenji asks if she would like to go to Disneyland with him. This gesture suggests his characteristic stoic demeanor hasn't completely dimmed his hope for the future, and it leaves the story on a positive, open-ended note despite the band's breakup.

Kenji's rediscovered passion for music during the festival performance hints that he hasn't lost his capacity for connection.

Kenji is chased by Ôba's gang while playing his recorder, but instead of fleeing, he bursts onto the stage still under pursuit. The chaotic scene transforms when he rejoins his band and Morita's group joins in. The crowd becomes captivated by their unexpected collaborative performance, turning the confrontation into a triumphant moment of musical unity.

Ôba devised a plan to teach Kenji a lesson, which plays out during this festival confrontation.

The day after their successful festival performance, Kenji reverts to his usual stoic self. In an empty classroom, he tells Aya that the band has dissolved, bringing an abrupt end to their musical journey. However, Ota observes this interaction and leaves with thoughts of reuniting the band, believing Kenji would likely be on board by the end of the day.

The film's tone balances chaos with indifference, and Kenji's character arc shows him returning to his default state despite momentary passion.

While wandering the streets lost in thought, Kenji unexpectedly witnesses a bold robbery. A passing musician notices the commotion and hands Kenji a guitar, which he uses to thwart the thief. This random encounter becomes the catalyst for Kenji's entire musical journey, as he keeps the guitar as his prize and shares it with his friends the next day.

The title "Our Sound" hints at the importance of music entering Kenji's life through this random event.

Aya becomes Kobujutsu's first and only audience member when she inquires about the name of their band. She attempts to support Kenji throughout his musical journey, even trying to reignite his passion when he becomes bored with rehearsals. Her heartfelt conversation with Kenji after the festival reveals her emotional investment in both Kenji and the band.

The trio's motivation to form a band includes wanting to impress Aya, establishing her importance early on.
