Haruka Nogizaka's Secret: Purezza contains episodes 1-12 of the anime directed by Munenori Nawa.

Since learning Haruka’s secret, Yuuto has had a lot to deal with: awkward first trips to notable nerd hangouts like Akihabara and the Comic Market, nosy sisters older and younger, rival love interests, and of course Haruka’s terrifying father. But despite the many precious memories they’ve made together, just where is Haruka and Yuuto’s relationship headed? When Haruka gets an opportunity to become an idol, her managers try to shut Yuuto out of her life. Yuuto has to make a choice: does he silently support Haruka’s budding new career from the sidelines, or does he trust Haruka with his heart, and declare what he really wants?
