The eighth collaboration between the “Kamen Rider Series” and the smartphone word-battle RPG Kotodaman (共闘ことばRPG コトダマン) begins on July 19, 2026. For the first time in a game collaboration, three Riders from the latest TV series Kamen Rider Zetts make their debut: Kamen Rider Zetts ExDream, Kamen Rider Nox Midnight Shadow, and Kamen Rider Dawn.
The Kamen Rider series has been a cornerstone of Japanese tokusatsu television since the original Kamen Rider premiered in April 1971. From Kamen Rider Kuuga in January 2000 onward, the franchise has maintained an unbroken run of TV series, along with numerous theatrical and streaming releases.
This eighth collaboration revives all summoning events and quests from the first through seventh collaborations, bringing together over 100 Kamen Rider characters in Kotodaman.
The highlight is the arrival of three Riders from the newest TV series Kamen Rider Zetts. Kamen Rider Zetts and Kamen Rider Nox will appear in the collaboration summon, while Kamen Rider Dawn will appear in collaboration quests. This marks the fastest game collaboration debut for all three Riders together.
Additionally, purchasing the “Kamen Rider G7 Pack” from the Kotodaman Web Shop or in-app store will grant players Kamen Rider G7.
A free “Kamen Rider Collaboration 8th One-Shot Complete Summon” allows up to 30 draws at no cost. If players obtain Kamen Rider Zi-O Trinity from this summon, they will also receive all six other collaboration summon characters from the 8th event (excluding Zi-O Trinity itself).
The collaboration runs from approximately 12:00 on July 19 to 15:59 on August 12, 2026. Full details will be premiered on the official Kotodaman YouTube channel “Kotodaman Official Broadcast [GOD Station]” starting around 11:30 on July 19.
