The tag implication #62673 ichi_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 ichi_inukai -> inukai_brothers (forum #403647) has been rejected by @slyroon.
