Same reason as yatogami_tooka --> yatogami_tohka.

Should not be done for the same reason as yatogami_tooka -> yatogami_tohka: tooka is correct under Danbooru's romanization scheme.

I went ahead and fixed a problem with the tag regardless:
yatogami_tooka_(true_form_) -> yatogami_tooka_(true_form), i.e. I got rid of the extraneous underscore.
