Talking about that, it would be nice to have legitimate evidence of the Yagami-ke famed status as an amazing Fighting Team, everyone in ViVid talks about how strong they are as a team but that's never showed onscreen. Hayate wil get her chance to shine as a capable field commander/heavy fire support once she manage to pull off the entire Wolkenritter in a battle which is supposedly the way the are most effective in combat.

For the moment their incredible teamwork performance is only an informed ability.
