From the introduction:
This game is about heroes. As a player you take on the role of a hero. Somewhere
in the streets of Tokyo a monster—a servant of the terrible Enemy you’ll have to face
one day—is going to hurt innocent people. He must be stopped. Luckily you’re not
alone; you’re part of an elite team with the power to stand up to the bad guys, to find
and extinguish the flame of evil.
This game is specifically about “sentai” heroes. Sentai literally means “fighting
team” in Japanese. It calls to mind Toei’s Super Sentai Series of tokusatsu (live action
special effects) shows that has been going on since 1975, and Power Rangers, the
American adaptation that launched in 1993 and is still going. There are many other
titles, tokusatsu, anime, and otherwise, that it inspired, in Japan and elsewhere.
