SHAFT, the studio who brought us Madoka Magica, has shared the fourth in a series of seven promo pilot videos for new mahou shoujo anime Magical Suite Prism Nana. This one features character design by light novel illustrator Kantoku (Hentai Ouji to Warawanai Neko AKA The Perverted Prince and the Cat Who Won't Smile), whose work will be featured in a promo illustration at Comiket 83 next week.
