I changed it to flow a little better: My interpretation was that Yukari was outright saying that the Hakurei team was NOT a team, as in they aren't united or whatever. Feel free to change it back if you find a better alternative.
Hey Reimu, don't lose!No wonder as they saw this outburst, which doesn't fit with team tactics. (Yukari)*irritated*Ah, well the Hakurei Shrine isn't a team. (Yukari)Alice Puppet ManufactureSanaee-Is that all!? Did they see that ace showdown was not worth it!? (Kou)Chill, Alice.Ooh, the three are slowing down!Go! Reimu!So, what now? Want to fight this out till we're exausted?They are mixing back into the main group! (Kou)You can read everything on the Moriya and Human Village Union teams' face. (Yukari)Well, seems like it... They could've simply not been serious. (Yukari)...Then again, they seem to have settled down, so there's no need for other teams to make a move.
