Who knows if Botan is the O Toyo of legend. But, based off that legend, she can change to the shape of people to get near her "intended targets." Coincidentally, if she can change into the shape of a human, it would seem more benificial to change her size from "giant" to of a normal house cat size.
As for future updates, can't say I'll get much anything posted until the summer. Though there may be filler art posted I can't say for certain.
