en.wikipedia.org/wiki/Oreimo

Official KADOKAWA sources for Ore no Imōto ga Konnani Kawaii Wake ga Nai Kuroneko If do not list Airi Mori as the writer. Instead, they distinguish between:

• 原作 (original work): 伏見つかさ / Tsukasa Fushimi
• 作画 (art): 森あいり / Airi Mori

For example, KADOKAWA's product page for volume 4 says: "原作：伏見 つかさ 作画：森 あいり", and BookWalker's series page likewise lists "原作：伏見つかさ　作画：森 あいり".

So the infobox entry attributing "Written by Airi Mori" is incorrect. Airi Mori is credited for the manga artwork/adaptation, while Tsukasa Fushimi is the original writer behind the story.

This sentence overstates the continuity between seasons. The official staff pages for season 1 and season 2 show that while some core staff members were retained (such as director Hiroyuki Kanbe, series composer Hideyuki Kurata, character designer Hiroyuki Oda, color designer Yasuko Suenaga, sound director Satoshi Motoyama, and composer Satoru Kōsaki), the staffs were not the same.

Examples of differences shown on the official sites:

• Season 1 lists スーパーバイザー：川口敬一郎 (Supervisor: Keiichiro Kawaguchi); season 2 does not.
• Season 1 lists 美術監督：衛藤功二 (Art Director: Koji Eto); season 2 lists 美術監督：岡本好司 (Art Director: Koji Okamoto).
• Season 1 lists 編集：宇都宮正記 (Editor: Masaki Utsunomiya); season 2 lists 編集：肥田 文 (Editor: Aya Hida).
• Season 1 credits 撮影監督：今泉秀樹 設楽 希 (Photography Directors: Hideki Imaizumi and Nozomu Shitara); season 2 credits only 設楽 希.
• Season 2 adds 渡邊敬介 as an additional 総作画監督 (chief animation director), which is not the same season-1 listing.

So the accurate description would be that the second season retained many key staff members, not that it had the same staff as the first season.

The article's sentence gives the wrong disc release date for the first pair of web episodes.

Official release pages show:

• Volume 7 was released on June 22, 2011, and includes episodes #12 TRUE ROUTE and #13.
• Volume 8 was released on July 27, 2011, and includes episodes #14 and #15.

So the second half of the sentence is correct, but the first half is not: the first two episodes were bundled with volume 7 on June 22, 2011, not June 27, 2011.
