I honestly do feel that Asuka is one of those characters that is underutilised in Ranma 1/2 fanfiction. Then again, I often feel that Rumiko Takahashi didn't make the best use of a whole bunch of characters throughout the series.
Also, in case you were wondering, I will be putting up a 3D comic this month! Still working on it... I'd intended to do something a bit different this month but it wound up taking a lot longer than expected. I'm going to aim to have that one out next month instead, with something else coming in the next few days.
