QQ Stand (Pixiv Fanbox)

I had no idea what to name this chapter. I just wanted to do another time stop with the sisters, but I didn't want to use another clock, so the next best thing that came to mind was... this? Anyway, I'd like to just post the question of what you think this guy's stand power should be - It doesn't have to be time stop or mind control related. Maybe he'll show up in , who knows.
