I've been noticing various 'group' tags for the Precure series:
blue_team_(precure)
green_duo_(precure)
leader_team_(precure)
red_team_(precure)
vice_leader's_team_(precure)
I don't see the point of these tags. A precure color_connection search would get the same results for the color-themed groups. If the whole 'leader' and 'vice-leader' teams are that important, the trait_connection tag can be used to connect them.
