|This article is about a/an DVD special in Kamen Rider Fourze.|
Kamen Rider Fourze Special Bonus DVD: Astroswitch Secret Report (仮面ライダーフォーゼ 特性ふろくDVD アストロスイッチひみつレポート Kamen Raidā Fōze Tokusei Furoku Dī Bui Dī Asutorosuitchi Himitsu Repōto) is a DVD packaged with the July 2012 issue of Televi-Kun magazine. The issue also comes with a poster with the information described in the DVD. The DVD is set before the Hyper Battle DVD, and features the content normally found in the Hyper Battle DVD (explaining the powers and weapons of the Kamen Riders), explained as Tachibana, with Ryusei and Gentaro's help, gathers the data of the 40 Astroswitches to find out what and where the mysterious mass of Cosmic Energy is.
- Gentaro Kisaragi (如月 弦太朗 Kisaragi Gentarō): Sota Fukushi (福士 蒼汰 Fukushi Sōta)
- Ryusei Sakuta (朔田 流星 Sakuta Ryūsei): Ryo Yoshizawa (吉沢 亮 Yoshizawa Ryō)
- Tachibana (タチバナ Tachibana, Voice): Nobuyuki Hiyama (檜山 修之 Hiyama Nobuyuki)
- In this special the Rabitt Hutch is aware of Kamen Rider Meteor identity, so it can only happen after episode 32. Also, in Kamen Rider Fourze the Movie: Everyone, Space is Here! every switch is distributed to students and teachers, but the switch detected in this episode is not. So it is safe to assume that this special takes place after the movie as well.
