Nepolabo (ねぽらぼ) — Momosuzu Nene, Omaru Polka, Yukihana Lamy, and Shishiro Botan — has released the official music video for ひとつになる声 (Hitotsu ni Naru Koe, “The Voice That Becomes One”), and the timing here is worth unpacking. The song itself isn’t brand new; it first released as a digital single back in August 2025, timed to their 5th anniversary. A full year later, it’s finally getting the MV treatment, landing right as the group marks its 6th.

A Song About Finding Your Way Together

The lyrics lean into themes of finding a guiding voice in the dark, running toward a shared dream, and trusting the people beside you to get somewhere none of you could reach alone — fitting territory for a song built around a four-person unit that’s stayed close for years. It’s a more sincere, anthemic counterpart to Hyper Jumpin’, the other original the group put out around this same anniversary window, giving the pair of releases a nice contrast: one built for jumping around at a live show, the other for a quieter kind of reflection.

Written by Ryota Nakano

Ryota Nakano (中野領太) handled lyrics, composition, and arrangement in full. Nakano trained on violin from age three before picking up guitar in junior high and moving into songwriting through high school, eventually studying music theory formally and building a career writing across anime, idol, and commercial music. That classical grounding shows up in the song’s structure, which leans on a soaring, string-friendly build rather than anything stripped-down.

The Visual Side

Illustration and video work both come from Rinu (りんう), with logo design by Hiiragi Ryo (柊椋), rounding out a release clearly meant to give this song the fuller visual treatment it didn’t get on its original 2025 release.

A Year-Long Anniversary Arc

Between Hyper Jumpin’ and this MV for Hitotsu ni Naru Koe, Nepolabo’s 6th anniversary is shaping up as a genuinely two-sided celebration — one new song built for pure energy, and one older song finally getting the spotlight it was always meant to have.
