Haha, that is really good! You should definitely continue with it, made me laugh... Poor Bya-san, having the untrained ryoka after his little sister! It's possibly he worst thing that could happen to him XD I like the idea of him plotting against everyone in secret (though it started making my think of Death Note, which I'm aout 2/3 of the way through atm. I hate it when fandoms cross over *lol*)

It really did make me laugh though, you should definitely pick it up. I want to see if the guy gets the girl (and if so, what happens to poor nii-sama and his twitchy eye! XD)
