I'm not comparing the two as series, which I agree are very different, I'm comparing characters in them. Both Kira and Kiba are little different, as neither get go very in depth, have no true development (like Soifon's development after losing to Yoruichi), and their main importance is in plot. Moving the Vizard and Bount were my idea, as it would improve the articles greatly if the members were added, otherwise they'd be regular start-class articles. And Kaien and Yachiru merged would be a bad idea right now. Also, the English series has already released volume 20, where Aizen is revealed as a villian and Gin and Tosen follow him, and in a few days over a month volume 21 will be released and Bleach will be in Shonen Jump manga, starting after the Soul Society arc. It just isn't spoilers anymore. 
 ::::And let's be honest here, merging someone like Kira or Shinji, who only play an important role in one arc, wouldn't be a bad idea, as we should try to concentrate on those who make appearances in several arcs (Toshiro, for example) and have too much information to merge (namely those well over 15,000 bytes). One Piece and Naruto, two major manga series even longer than Bleach, don't have half the number of character articles Bleach has, and they only give them to those who have been continuously important throughout the series and have enough information, and they don't have overly-long plot sections (Sasuke Uchiha and Kakashi Hatake, two main characters, for example). The Bleach articles need to follow their examples in this subject. In the end, Kira or Shinji are only one-arc characters that do nothing major besides one specific thing (in order, following Gin Ichimaru as a lackey and training Ichigo), and fall out to major characters like Hitsugaya or Aizen, who do have enough outside-of-plot information and play the major roles. We should try limiting the number of articles to no more than twenty, as only that many can truly be called major in any major manga series. For Bleach, that would be those listed .
