From the poll on the front page, it looks like the vast majority of respondents found this series through the anime, not the light novel or manga. So for convenience, it'll probably be easiest to stick with whatever spellings are used in the anime. These will be the most widely recognized among visitors...

For example, even if the lesser-known LN name are used as the standard here, as more vistors come to the site and edit pages, they'll probably still use the anime versions as they work on different sections. I've worked professionally as an editor in the real world, and trying to get people to use any name variant other than the most commonly-recognized standard is kind of a losing battle.
