Alias Koikatsu

BUR #6970 has been rejected.

create alias koikatsu -> koikatu

Saw it kinda often in the missed searches and the koikatsu wiki just states to search for koikatu. So I think it can just be aliased to the koikatu tag.

Only related topic #16206.

It should be reversed. The steam page even refers to it as koikatsu.

Not to mention the direct sequel that was released a few weeks ago is romanized as Koikatsu Sunshine. Aliasing to koikatsu will be more preferrable for consistency's sake.
