The characteristic of Kyousuke reminds me of
Tomoki in Sora no Otoshimono who is also just wanting common and peaceful everyday life. But anyway they are much different in many aspects (explicitly).
I think Kyousuke is really a good brother. He is caring and do good to his younger sister. But one thing I should point out is that he is too lack of control over his sis
. Hope he'll build his prestige at last.
