Aiobahn +81 teams up with hololive English’s FUWAMOCO for “side by side”, a vibrant ending theme for Nekopara After La Vraie Famille. The track fuses melodic house with otaku culture, featuring nostalgic vibes and playful “Nya Nya” chants as a tribute to the beloved catgirl franchise.

FUWAMOCO’s soft vocals blend seamlessly with Aiobahn’s upbeat production, creating a sound that’s both emotional and danceable. The song also comes with exclusive artwork by Sayori, Nekopara’s creator, and a retro anime-style lyric video starring the artists alongside fan-favorites Chocola and Vanilla.

More about Aiobahn +81:
Aiobahn +81 is the alternate moniker of music producer/DJ Aiobahn, who is rooted in electronic dance music and deeply connected to Japan’s subculture scene. Launched in 2025, this alias allows Aiobahn to explore a completely different creative identity – one focused on otaku culture, including denpa, internet music, anime songs, and game soundtracks. While distinct from his main work as Aiobahn, Aiobahn +81 represents a bold foray into more niche, genre-blending art.
His debut single under this name, “天天天国地獄国 Tententengokujigokugoku (feat. Nanahira & Pmaru-sama)”, dropped on 5 February 2025 and quickly gained major traction online.
