BUR #32825 has been rejected.
create implication luluco -> trigger-chan
According to the wiki, Trigger-chan is an older Luluco. I think Trigger-chan came first, and therefore she gets to be the main tag.
On a related note, Luluco's name is a bit awkward because in Japanese it's spelled exactly the same as Luluko, which causes both to be present in translated tags. I think at least one of them needs a qualifier.
