A guy stuck in domestic limbo with two versions of the same girl, neither of them actually his wife, and the show treats it like a genuine problem instead of a punchline. The comedy lives in the exhaustion of just trying to keep two Valkyries fed and happy while nobody's timeline makes sense. Romance doesn't move forward here, it just pools around him like water finding its level, patient and warm.
Kazuto's life has spiraled into complete chaos. After the events of the previous season, he's now responsible for two Valkyries: a spirited teenage princess and her younger counterpart. Both live under his roof, both depend on him, and neither shows any sign of slowing down the constant mayhem that follows them everywhere. The marriage question still hangs over everything. Everyone expects it to happen. No one agrees on how or when. Meanwhile, Kazuto just tries to keep the household functioning while juggling the impossible demands of caring for interdimensional royalty who treat domestic life like an endless game. Comedy erupts constantly as the Valkyries clash with each other, drag Kazuto into ridiculous situations, and generally turn his world upside down. Romance simmers beneath the surface while sci-fi absurdity keeps things unpredictable. This OVA leans hard into the zaniness that defines the franchise, embracing pure entertainment over coherence. If you want lightweight fun with zero pretense and maximum weirdness, this delivers exactly that.
