The tag implication #62675 san_inukai -> inukai_brothers has been rejected.

Reason: Ichi Inukai, Nino Inukai, and San Inukai are brothers, matter well group them together in one tag inukai_brothers so you can find any picture featuring one of them instead of searching for them separately.

I'm not sure if we want to make any more group character tags like this and we've had some semi-recent discussions on what we want to do with the existing ones.

for the "any imply group"-type ones like koopaling and the one suggested in this thread I feel like there's some utility, but it's gotta contain quite a few more than just three characters with very easy-to-remember names for it to make sense.

It's only three characters and they all seem to be from the same artist. It would make more sense to have a pool instead if you really want to group them together. Even if you don't want to make a pool, you can just search ~san_inukai ~nino_inukai ~ichi_inukai so any picture with at least one will show up. In my opinion, creating group tags are really only necessary if it would be infeasible to put it all in a pool or search it.
