The "Heisei Ultraman Series" pyramid "Ultraman Tiga" started broadcasting in 1996 and will celebrate its 25th anniversary next year. It is a work that has been extremely popular to this day. The subsequent "Ultraman Dyna" in 1997 and "Ultraman Gaia" in 1998 are affectionately called "TDG/Heisei Three Heroes" by fans. In addition, "Ultraman Zeta" which started broadcasting on June 20 this year has gained huge popularity. The children of the "TDG" generation have become parents, and they watch the new Ultraman with their children and become new Ultraman fans. This work representing the Heisei and Reiwa era, "Tiga" and "Zeta" will be intertwined to introduce the heroic stories of the giants of light led by Tiga and Zeta. The adventure stories of the Ultra Heroes will be presented to everyone. The program commentator is Ultraman Zero (voice: Mamoru Miyano), who connects the world of "Ultraman Tiga" and the world of "Ultraman Zeta" and can travel back and forth between these different worldviews and parallel universes. He will tell the stories of different Ultramen.
