This had already come up in the Ryusoulger discussion, but it's now official so I figured it deserved it's own thread too.
So for those who hadn't heard, the last episode of Lupinranger vs Patranger will air on February 10th. However, Ryusoulger will not begin until March 17th. This leaves four Sundays in between, which will be filled by this new mini-series which is being created to mark the end of the Heisei era (and totally not so that Ryusoulger will debut a month later against different TV/toy competitors, no siree).
The mini-series will be written by veteran toku scribe Naruhisa Arakawa (Kuuga, Abaranger, Dekaranger, Gokaiger, Akibaranger) and directed by the man who badly needs to take a cold shower, Koichi Sakamoto.
The story begins when a mysterious girl named Rita gathers heroes from Super Sentai teams to the planet Nemesis. The heroes are told that any wish they desire will come true if they can win the “Super Sentai Greatest Battle” tournament.
The mini-series will focus on Captain Marvelous (Gokai Red), Kagura (ToQ #5), Takaharu (AkaNinger), Yamato (ZyuOh Eagle), and Stinger (Sasori Orange), but hints that other heroes could also appear.
