Thanks for the link, will continue the conversation here: first, great job done creating this! Are you all right with translating the articles? With different languages it's fine to copy from the English Seraph of the End Wiki to translate to Japanese here.
Like the other different language SotE Wikis this one can have it's own unique design! For the main page look, navigation templates and the like it might be worth having a look round at other wikis to find some inspiration of what design you would like to emulate.
Once there are enough articles and everything is established we can then create the interlanguage links between the lanugage wikis we have with this Japanese one!
My pleasure, since this is a great project to undertake (though an easy sailing one since it is translating articles) did you want to make your own designs for infoboxes, and the overall feel of the site? As said having each site have it's own look would be nice.
Also with, say Yu's article (the first part seems good to translate since it's a nice overview) you could have your own layout for this Japanese version, but again assume you have your own ideas and a new wiki like this is an ideal testing ground!
Sure, up to you, so long as the wiki has the article information in Japanese that's all that counts. Seeing the pages translated will be impressive, and then if you had design ideas for infoboxes, templates and the like we can plan those, too!
ps excellent going with the other message as well, remember this wiki is still your blank slate to have whichever look you like!
