Minato is a boy who stopped playing water polo due to a certain incident in the winter of his third middle school year. He picks the sport back up again with a new team when he starts in high school, but the fledgling team runs into many problems.

Since 1975, Japan’s iconic Super Sentai series has defined the tokusatsu landscape. Now, after 50 years, Japan’s weekly tokusatsu broadcasting timeslot will welcome a brand-new project by Toei titled, PROJECT R.E.D. (short for Records of Extraordinary Dimensions). PROJECT R.E.D. is a new tokusatsu series featuring a red hero in action.

Seeking the truth behind the "Biscatonic Cluster Incident", which claimed an unprecedented number of victims and turned Death Gavan evil, Gavan Infinity —Reiji Doki— sets out for Planet Alkam, one of the planets where the incident took place. There, Gavan Raiya —Kunai Kazanami— who was tracking Death Gavan’s whereabouts, also appears from across dimensions…

Negative Emorgy emanating from MultiEarth A0073 coalesced into a massive void that swallowed the sun. The world lost its light and was engulfed in deep darkness. The most formidable enemy, Gavan Killer, who aims to annihilate all Gavans, pushes Reiji and his friends into an unprecedented life or death situation.

A group of high school students are forced into a game where they are hypnotized to commit suicide on an unknown command. Where no one is safe from a sudden death, how can they avoid their fates?

Use the Gavarion Trigger to Jo-Chaku! You too can master "Jo-Chaku"! Be sure to check out Gavan Infinity's battle too!

The story unfolds in the worldview of multiverse theory, where there is not just one universe. In the overlapping multiverses labelled as "Cosmo Layers", there exist other Earths that are identical to the Earth we live on. Gavan Infinity is a Space Sheriff who can transcend dimensions. What kind of cases will he solve in the diverse dimensions he is set in, and why can he transcend dimensions? A new Gavan legend never before seen begins!
