And there is already some heavy spoiler about the new novel... I shouldn't have read that...
Spoiler for HEAVY spoiler for novel 8:
http://yaraon.blog109.fc2.com/blog-entry-1792.html = So Kyousuke got scolded by Ayase and Manami, was dumped by Kuroneko and is hated by all(?) girls in his school... But he and Kirino got a lot of development...
What I can say now is that Kyousuke is really a tsundere siscon and less Kuroneko deredere is a huge letdown for me =/
