Years ago, a battle between every race of the Messier 78 Galaxy against a threat known as the Nyctemons breached the metaphorical barrier between humans and Seijin and allowed both to work together. In the process, a new society was established, and Seijin came to reside among humans and vice versa. Ichika Akimoto is a young woman who is just barely reeling from the aftermath of a divorce from her abusive ex-husband. Shin is a young Ultraman carrying scars from the actions of his abusive ex-wife. Both of them want and feel they have to stifle their traumas for the sake of their daughters, so what happens one day when a false allegation leads one to seek out the other for safety? Could it be a brief partnership out of necessity? Or will more occur between them?
