As nice as it is to see the Nishizumi sisters on the same side, I always thought Miho found it a bit awkward to be on the same team with Maho, whether as her commander(she can't bring herself to call Maho "Onee-chan" in front of her teammates), or as her subordinate(in Phase: Erika, Maho insists that Miho think of her as a commander first and a sister second while they're around the team.)
