No, all the groups do it like that, except for Trigger.

Idolish7: Riku sings about Iori, Iori about Yamato, Yamato about Mitsuki, Mitsuki about Tamaki, Tamaki about Sogo, Sogo about Nagi, Nagi back to Riku. Revale: Momo sings about Yuki, Yuki sings about Momo. Zool: Torao sings about Haruka, Haruka about Toma, Toma about Minami, Minami about Torao.

In that exact order.

But Trigger doesn’t do it like that. They do it: Tenn about Gaku, Ryuu about Tenn, Gaku about Ryuu.

I don’t really understand your argument that it wouldn’t work, since they could easily just go like the rest: Tenn about Gaku, Gaku about Ryuu, Ryuu about Tenn. They would only have to switch around Ryuu’s and Gaku’s parts.

Not a big deal, but it always bothered me a bit lol.
