'''What as the extra member. Well personally I think Nanobana Kinako could be the extra member or Kariya.'''

Reasons:

'''Kinako: She lost her chance to Mixi Max with Jeanne. I know it was for a good reason and she shouldn't of been chosen in the first place but still and shes been with Raimon the whole time whilst Taiyou who joins Raimon gets to Mixi Max and with a woman!! I personally think Kinako should of Mixi Maxed with 'her'.'''

'''Kariya: I really hope he isn't but he does look like a likely candidate as he has been with Raimon longer and he has nothing released and he doesn't even have a Keshin. I know Kirino didn't either but still I think Kariya might be missing out I mean now Hikaru looks more likely.'''

'''To be hounest I really want both of them as I really want to see Kinako, Tenma and Tsurugi using Fire Tornado TC in either their Mixi Max forms or Keshin Armed forms. And I can see Kariya and Kirino using a Go/Chrono Stone version of Twin Boost, that would be super epic or a new version of Killer Fields!!!!'''

All of this is just my opinion based on what I've seen from start to Episode 27.
