Looking for Kira Takenouchi? She’s at Patreon, here. Yes, she’s back, and has been back for quite a while. Join here there for all your favorite stories, including this one, which is Grayson’s Tower (or, at least, the art for it, by Shuangwen).
Oh, and for your information, Taming Riki Volume 3: Alpha Zen is underway there, as well.
