猫汰つな (Nekota Tsuna) of competitive gaming VTuber agency ぶいすぽっ！(VSPO) drops her original song ガチ炊きちゅーなの！？ ALL NIGHT LONG (Gachitaki Chūna no!? ALL NIGHT LONG), and it’s one of the most perfectly matched artist-song pairings in recent VTuber music. Composed, arranged, and mixed by D.watt (IOSYS) — with lyrics by his own alias 七条レタス (Shichijō Retasu) — this is a full-throttle denpa track built entirely around FPS gaming culture, parasocial all-nighters, and the very specific chaos of watching Tsuna play ranked until sunrise.
What ‘Gachitaki Chūna no!?’ Sounds Like
This is classic IOSYS energy: high-tempo, hyperactive, crammed with call-and-response crowd sections and enough earworm hooks to occupy your brain for a week. D.watt leans fully into his denpa roots here — rapid-fire vocal delivery, punchy electronic production, breakdowns that feel pulled straight from a Nico Nico Douga flash era — but the execution is sharp and modern. It doesn’t feel like nostalgia bait; it feels like a producer who built this sound from scratch and still knows exactly what he’s doing with it.
The mid-song interlude is a highlight: Tsuna breaks from the song entirely to introduce a fake new game segment called “FPSじゃんけん (FPS Janken)” — rock-paper-scissors where guns beat grenades, grenades beat cover, and cover beats guns — before launching into a full audience call-and-response chant. It’s absurd, it’s completely in character, and it works because the whole track is built on that kind of streaming-native chaos.
Tsuna’s Vocal Performance and the VSPO Fit
The title packs in three layers of wordplay: “ガチ炊き (gachi-taki)” is FPS slang for getting absolutely dismantled by someone — tilted, destroyed, cooked — “ちゅーな (chūna)” is Tsuna’s own affectionate self-nickname, and the “ALL NIGHT LONG” makes it clear this is a sleep-deprivation situation. The song is essentially about a viewer who can’t stop queuing up matches with Tsuna until the sun comes up, losing their mind in the best possible way.
Nekota Tsuna sells every bit of it. Her delivery is loose, reactive, and full of the same energy she brings to her actual streams — the trash talk sections, the mock frustration, the sudden warmth of “誰でもじゃないよ 君との ALL NIGHT LONG (it’s not just anyone — it’s an all-nighter with you)” land because she sounds like she means them. The audience cue sections are designed to be screamed at live events, and you can already hear how they’ll translate.
D.watt and IOSYS: Why This Credit Matters
D.watt is a founding member of IOSYS, rooted in Akihabara subculture and known for fusing club sound and dance music techniques with denpa and internet otaku culture. What makes this credit notable is that both the music and lyrics come from the same person — D.watt composed and arranged the track, while his lyricist alias 七条レタス (Shichijō Retasu) wrote the words. The two names are the same person. The result is a song where the production and the lyrical content are in complete lockstep — the chaos of the arrangement mirrors the chaos of the words, because they were built together by the same mind.
D.watt has described his VTuber work as incorporating not just character settings but streamers’ personal quirks and shared listener episodes from their actual broadcasts. That philosophy is all over ガチ炊きちゅーなの！？ — the song reads like someone watched a lot of Tsuna’s FPS streams and distilled the whole experience into three minutes of controlled mayhem.
A Song That Knows Exactly What It Is
Not every VTuber original needs to be a statement piece. Sometimes the best thing a song can do is be the most fully realised version of an artist’s existing energy — a track that fans immediately recognise as theirs. ガチ炊きちゅーなの！？ ALL NIGHT LONG is that for Nekota Tsuna. The choreography by わた (Wata), animation by cacaotane, and illustration and MV direction by ひとびと (Hitobito) round out a package that looks and feels as cohesive as it sounds.
This one is going to be loud at lives. And it was clearly made to be.
