Is the same person who made "Hyperdimesion Neptunia" the same person who made 日期 A Live? Because it seems that way to me

From what my friend Kevin Smith told me is that the person who did the designs for HyperDimension Neptunia. Also did the designs for 日期 alive Anime. See in a way 你 can see the character designs similarities. I hope this helped 你 alot. 😁
