A kid just wants to look cool, and the song says what he's too shy to say out loud. The animation moves like the music breathes, nothing wasted, everything in its place. You finish it in under four minutes feeling better than when you started, which is exactly what a perfect children's song should do.
A single music video set to Mariko Koga's upbeat track, "Boku Kakkoii Deshou" captures a moment of youthful confidence and self-assured swagger. The song pulses with infectious energy as the visuals follow a character navigating everyday moments with an unshakeable sense of cool. Whether walking down a street, striking a pose, or simply existing in spaces around them, there's an infectious charm in the protagonist's belief that they've got style for days. The animation style keeps pace with the song's rhythm, delivering vibrant frames that match the track's playful attitude. What emerges is less about plot and more about vibe: a brief, potent burst of that specific feeling when you're convinced you're the coolest person in the room. The piece celebrates swagger without pretension, poking fun at self-assurance while somehow making it feel genuine. This is the kind of short that works best watched with zero expectations, letting the song carry you along. Perfectly suited for anyone who appreciates bite-sized bursts of personality and animation that knows how to have fun with its runtime.
