I feel like Ayase is quite dangerous because of the anime atmosphere - -'.
Kyousuke alway make many misunderstand confession
, his idea/reason alway was great when come to defend for Kirino
, thumb up for him. Become Kirino's brother is not a easy job.
Another thing about this episode is I think Kirino should not said bad about otaku when she bump into Ayase (since herself is a otaku too). Moreover it is point to her friend, which is a very bad, will hurt others and ownself. Well, it is just my opinion.
