On Wednesday, the Okamisan (Ōkami-san to Shichinin no Nakama-tachi) anime's official website posted the cover image of the free "Maker Ōdan Anime Guide 2010 Summer" pamphlet, and the cover lists a previously unannounced Hidamari Sketch × ☆☆☆ work. The website posted the cover image to announce that Okamisan is part of this guide to the anime industry, but the cover also lists 47 other works from nine makers. The guide will be distributed at the Comic Market 78 event in the Tokyo Big Sight convention center from August 13 to August 15.

The Hidamari Sketch × ☆☆☆ television anime series — the third one in the Hidamari Sketch franchise — already premiered this past January. The previous two television anime series — Hidamari Sketch and Hidamari Sketch × 365 — each spawned a special mini-series, but a similar special mini-series has yet to be announced for Hidamari Sketch × ☆☆☆.

The Hidamari Sketch anime franchise adapts Ume Aoki's manga about a high school for the arts and the everyday life of four of its students. Director Akiyuki Shinbo and the studio SHAFT animated all three television series after working on Magical Girl Lyrical Nanoha and MoonPhase.

Sentai Filmworks licensed the Hidamari Sketch and Hidamari Sketch x 365 television anime series in North America, and Section23 Films distributed these two series on DVD. Yen Press published the fourth volume of the original manga (under the name Sunshine Sketch) in January.

Update: Aniplex's publicity representative Yuma Takahashi ("Aniplex Yuma") wrote in the Anime Maker Ōdan Sendenman Blog on Thursday morning that there have been times when Aniplex's mistake accidentally revealed something, but this is the first time something has been revealed for them.
