The end of the Heisei Era has arrived, and to celebrate the 20th and final entry in this chapter of Kamen Rider a new king has risen who is heir to the power of all Riders. His name is Kamen Rider Zi-O, and 10th anniversary series Kamen Rider Decade his series will commemorate all of the previous Heisei Riders to date. This comes not only in the form of the Ride Watch gimmick line and Ride Armour forms, but also cameo appearances from past actors, Rider-themed monsters and more. Heading the writing and directing of the series are Kento Shimoyama (Shuriken Sentai Ninninger, Kikaider REBOOT and most recently the Gorider miniseries) and Ryuta Tasaki (a man involved in nearly all of Heisei Rider, as well as both Super Sentai and Power Rangers) respectively. Its opening theme "Over Quartzer" is performed by Shuta Sueyoshi and ISSA – the former having previously performed "Climax Jump" for Kamen Rider Den-O and the latter "JustiĻ's" for Kamen Rider 555. Even before you get into the series itself, there's plenty of callbacks going on here.
