Since I first found her HinaxSayo artworks, I've been following Arupa-san from a while. Unfortunately, she mass-deletes all her content from Twitter/X, Pixiv and Weibo from time to time. A little while ago, she admitted that many of her early artworks were permanently lost. Fortunately, I think I managed to save the vast majority of them (the BanG Dream! ones anyway). At the time of writing, her active social media are:

In addition, some of her artworks can only been seen on AKUZIHS1-san social media (listed below). She is a novelist who frequently collaborates with Arupa-san and commissions art from her as well. This images are also included in this gallery. The two doujinshi from her Pixiv account are already uploaded on this site. Her social media are:
