Aiobahn +81 x FUWAMOCO drop ‘Side by Side’ – Nekopara’s New Ending Anthem is here!

Aiobahn +81 and FUWAMOCO  Team Up for High-Energy New Track “side by side” —A Summer Anthem for Nekopara Fans.

Internet music meets otaku dream collab: genre-bending producer Aiobahn +81 drops his electrifying second single, “side by side (feat. FUWAMOCO)”, as the official ending theme for the newest chapter in the globally beloved bishoujo game series, Nekopara After La Vraie Famille.

Rooted in electronic dance music but steeped in the DNA of anime, game, and denpa culture, “side by side” is a melodic house track laced with shimmering nostalgia, channeling the golden era of bishoujo game theme songs – but with a 2025 energy. Floating atop the airy summer beats are vocals by FUWAMOCO, the twin chaos queens from hololive English whose sweet, airy delivery adds a dreamy texture to the track. The duo – winners of the VTuber of the Year at the 2024 VTuber Awards – boast a fanbase of over 1.1 million YouTube subscribers, and they’re vocal superfans of the Nekopara series itself.

The result is a track as emotional as it is danceable, peppered with playful cat-like chants of “Nya Nya Nya…”, a lyrical nod to the beloved feline cast of Nekopara, which has sold over 6.5 million copies worldwide since its debut. The tie-in goes deeper: the single’s cover artwork is an original, exclusive piece drawn by Sayori, the famed illustrator and creator of Nekopara, featuring Aiobahn +81 and FUWAMOCO together for the first time.

Aiobahn +81 isn’t just a remix – it’s a full-blown reinvention. The moniker is a new identity Aiobahn launched in 2025 to dive headfirst into otaku-centric subcultures: think internet music, denpa, anisong, and game soundtracks, all wrapped in digital maximalism. His debut single “天天天国地獄国 Tententengokujigokugoku (feat. Nanahira and Pmaru-sama”, racked up 9.5 million YouTube views in just four months and cracked the Billboard Heatseekers Chart (No. 10) in May 2025 – proof that his sound is resonating loud and far.

The lyric video for “side by side” evokes the soft-focus sentiment of a 2000s anime ending, complete with appearances by Aiobahn +81, FUWAMOCO, and Nekopara’s fan-favourite catgirls Chocola and Vanilla.

Whether you’re a music head, a VTuber stan, or a Nekopara loyalist, this is one collaboration that checks all the boxes: otaku nostalgia, futuristic beats, virtual charisma – and cats.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.About FUWAMOCO

Fuwawa Abyssgard
The soft and fluffy half of the mischievous twin duo known as the “Guard Dogs of the Demon Realm”, Fuwawa once caused so much trouble that even the gods had her imprisoned in the great penitentiary known as The Cell. She’s the calm overseer of her energetic twin sister Mococo and their pet Pero – though “calm” is relative, as Fuwawa herself loves to chat, play, and stir up some chaos.

Mococo Abyssgard
The more energetic and wild twin, Mococo shares a similar divine rap sheet, having also been locked away in The Cell for divine-level mischief. A known anime and game fanatic, she spent her time in confinement bingeing her favourite content, and frequently roped in her sister Fuwawa and pet Pero to join the fun. Rumour has it she only joined their prison break because it “sounded fun”.
