An editing suggestion is to have in universe descriptions for characters on the articles. Whereas this comes across as a fan based opinion and somewhat sensationalized (it may be true but where the article is concerned being to the point is helpful, besides share such views in user areas like Discussions here!), this example documents the facts as other characters say them.
Another idea that could be good is relationships sections that could be helpful to note how each character interacts with one another. This would document story information as well as character trait information, similar to this example. Indeed as with Jian Yi's article expanding these to other character pages makes sense!
Still, whether that sounds like a development for the articles, to expanding existing information, creating further pages on characters and chapters, discussing the source material here in Discussions, whichever helps the wiki, series and what everyone enjoys the most is best! 🎉
