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.
EDIT: The tag implication san_inukai -> inukai_brothers (forum #403649) has been rejected by @slyroon.
