Who is the best Onii-chan?
I am the greatest Onni-chan ever.
You can ask the only person who matters, sweet perfect imouto.
Stop watching shit shows.
temporarily a good oniichan counts? You know he'll scorn his imouto once she gets older. But right now? I'd hang out with him, enjoy cuties.
not a total fucking faggot, and sticks to one girl ( in each respective arc.)
Kyousuke is a better Onii-chan than Haru by a pretty wide margin.
Yes, that is what they do.
