User blog:Taritsukii/Seiyūs- First or last name first?

Hello again everyone!
This isn't really a big issue, but I've been editing a lot of music on the wikia and whenever I need to refer to the seiyuus who sang them, I have trouble finding out which version of their name I should use.

I know that we already have articles created for some of the Seiyūs, but the titles for each article vary because of their name. What I mean by this is that some articles have the Seiyū's first name first (e.g. Haruka Nanase) while others have their last name first (e.g. Nanase Haruka). So I guess the question is, should the first or last name go first?

From my knowledge, these are all the currently existing Seiyū articles (As of 30/11/2018):

I guess I should ask first, should we change them all to match one of the options?
Like I said before, it's not a really pressing matter, but it would be nice to have that consistency with names. If we do decide to change them to fit either option, I would be happy to offer my assistance in doing so :) The only things I won't be able to to are editing the main wikia tabs, removing old versions of articles (e.g. Uchiyama Kōki's original page called 'Uchiyama Kouki'), and removing categories (with the wrong names) from articles as I lack the access to edit those things.
