The homepage does look nice, but could use some more refining (especially the right column). I formulated a Widget box to use and drafted up some widgets.
NOTE: These are just drafts, they can be tweaked.
I feel Tech Support links (actually, most of those external links) would be better placed in the Hatoful Boyfriend: A School of Hope and White Wings page under an External Links section since having it on the homepage doesn't really serve that much purpose considering people are more likely to land in the Hatoful Boyfriend game page when Google searching. I've learned very few people go on the homepage so it's better served as a means of advertising what's on the wiki.
In place of the Wiki Updates feed, I feel it would be better to have either a blog feed or a forum feed to better advertise those to visitors. Then people would be able to see what needs to be worked on rather than stuff that's already being worked on.
