: A realm defined by a spectrum of "rainbow" colors (as the name niji suggests).
: Instead of a morality system, Final Nijiirononiji uses a Fragment Map . Each exposed truth becomes a colored shard. Arrange shards in different orders to unlock multiple endings. There are 12 endings, but only one is considered the "True Roshutsu Ending."
: This term can be translated to "eruption" or "outing" in English, depending on the context. It might refer to a character from a game, a game title, or a concept related to an "outing" or "eruption."
