Kanda Shoichi (神田笑一), Doura (ドーラ), Sister Claire (シスター・クレア), and Sogo Nonoha (十河ののは) have released a joint cover of ナイワ (Naiwa), and the confidence baked into the original song makes it a fitting pick for a four-way collab — this is a track built entirely around the swagger of not needing anyone else.
A Song Built on Senior-Class Swagger
Naiwa comes from Gakuen IDOLM@STER (学園アイドルマスター), written, composed, and arranged by Saeki youthK as the class song for the game’s 3rd-Year Class 1 unit, released in September 2025 as part of the “Class-vs-Class Sports Day” event lineup. The concept behind it was deliberately built to “reach for colors first-years could never touch” — a rap-driven, effortlessly composed track meant to embody the kind of unbothered confidence only an upperclassman could pull off. The repeated hook, “ナイワ” (“there isn’t,” playing on the idea of having no rivals and no weaknesses), carries that attitude through the whole song.
Four Very Different Voices
Splitting a song this boastful across four vocalists changes its shape in an interesting way — instead of one performer carrying that swagger alone, it becomes something closer to a shared statement, four different voices all equally certain nobody’s catching up to them. Kanda Shoichi, Doura, Sister Claire, and Sogo Nonoha each bring distinct vocal identities to Nijisanji’s roster, and trading off lines on a track this rhythmically demanding gives all four a chance to show off their range.
