2015's Super Sentai Name Revealed in Trademark Filing?

A trademark filing suggested that the name for the 2015 Super Sentai series had surfaced ahead of any official announcement. According to shared translations, the filing named the show “Shuriken Sentai Nin’ninger,” pointing to a ninja theme, a motif not used in Super Sentai since Ninpuu Sentai Hurricanger in 2002. No further details were available at the time of the report, and the finding was treated as an unconfirmed rumor pending an official reveal.
