it looks like it was drawn by Toybox

Was thinking that myself, but the page is named aerialrave, and my Japanese is nonexistant, so I was leaving the decision wether to tag it with toybox to someone that is not me.

Not to mention that there is no toybox tag.

Are we talking about the same Toybox/Kurikara here? Because it definitely doesn't look like Toybox to me.

Aah if it's named aerialrave then that's definitely toybox. I've got their Doujin "Satsuki Milk" right here and their website is listed as aerialrave.com.

In that case, I am beffudled by the nonexistance of a toybox tag.
