Noel's most iconic outfit is her NOL uniform though. And the ending is ambiguous for a number of characters. For example we have no proof that Kokonoe rejoined Sector Seven; we see her in a lab but we aren't told her status. Better to be inclusive and have both current and former members in a category. Roy was defined by his time in Sector Seven for example, so it seems wrong to remove him just because he's a former member.

There are characters that don't belong to the Immortal Breakers from BE who also have the ability to kill immortals. Tsubaki and Mai both have weapons capable of doing that for example. And the Ten Sages were a group that ruled Ishana rather than a level of magical ability. Xblaze even made it clear that you didn't need much magic power to get in if you had the political influence necessary to get existing sages to vote for your inclusion.

Shiori didn't have some sort of entrance ceremony, but the fact she learned what the group was for and participated in the group's activities made it clear that she joined Team Remix Heart. Unlike say Chachakaka, who also knew about the group but stayed out of it. And the ending where Mai asks about whether the group should break up has Shiori arguing against that, which shows she was part of it.
