Bandai Namco registered the new trademark for Towa and Guardians of the Sacred Tree in Europe on January 22, and the company usually registers trademarks a few months before the official unveiling of its projects.
Examples of trademark registration before the official announcement include Fires of Rubicon, which turned out to be the side title for the sixth part of the Armored Core game series, and the Sparking registration! Zero, which turns out to be related to the game Dragon Ball: Sparking Zero! And other examples.
