kugajou_takaya -> naruse_hirofumi
Reason: This looks to just be a pseudonym. Naruse Hirofumi's website is linked and his name is in the text of many of the images for Kugajou's Pixiv account. EDIT: Looks like I'm mistaken about them being the same person, so the alias probably shouldn't be done. Kugajou isn't the artist, though, so the images were rightfully moved by henmere.
