Afterward
Thank you for buying "Onii-chan wa Oshimai!"
As a doujinshi, this is part of a still-developing niche genre, but
it still managed to be released as a commercial comic.
The story still hasn't finished, so please keep up the support so
we can get volume 2 out!

Also, this product also has a drama CD!
You can only obtain it through the doujin shop or mail order,
but there are plans for it to be sold via download
so please enjoy it together with the comic.

So then, until we meet again!
