It's been 9 months since we first reported on a 3rd season of Nogizaka Haruka no Himitsu and 3 years since the last installement of the anime which is based on a series of light novels. Since then we haven't heard a peep about the subject until now. The official Dengeki website has announced that the series will be concluded as 4 OVAs which will release 1 month apart from each other. The OVAs, entitled Nogizaka Haruka no Himitsu Finale♪, don't have a release date as of yet but plan to cover the climax of the series. Presumably this means a confession and happy ending for the protagonist and the series' closeted-otaku namesake.
