The show sets up ridiculous marriage scenarios and immediately throws the worst possible people into each one. A bride-training boot camp where Kazuto has to cook for an alien princess, his sister has to survive poverty with her crush's ex, and a literal demon couple plans a wedding. It's pure escalation comedy that doesn't care about making sense, only about watching everyone fail spectacularly at domestic life.

The Queen of Valhalla has arrived on Earth with a virtual-world program: a bride training boot camp meant to prepare people for married life. The cast is split into pairs, and each pair draws a random card describing a situation a married couple might face. Kazuto and Valkyrie must cook dinner together. Raine and Kazuto's sister have to cope with poverty. Akina and Hydra must plan a wedding ceremony as bride and groom. The catch is that everyone ends up with the least likely and least suitable scenario for them. The special is a one-episode sci-fi romantic comedy with ecchi touches, built around these mismatched assignments.
