It opens with Hisashi Seki waking up next to a naked girl and then spends the rest of its single OVA runtime refusing to explain itself, and that refusal is the whole point. This is 1986 direct-to-video comedy at its most unbothered: cute, soft character designs doing absurd things inside a plot that never quite assembles, closer to a fever dream with a punchline than a story. People reach for Urusei Yatsura when they describe it, and the comparison holds in tone if not in coherence, because the joke is your own confusion. It is genuinely a so-bad-it's-good watch, the kind you finish and immediately make a friend sit through so you can watch their face. Half the room drops it in ten minutes. The other half never shuts up about it.
Hisashi Seki's morning takes a bizarre turn when he discovers a naked woman in his bed with no memory of how she got there. She claims to be a witch from another dimension, and her arrival wasn't exactly planned. Now stuck in his world due to a magical mishap, she becomes an unwilling houseguest with zero social skills and a talent for accidentally destroying his apartment. What follows is a comedy of errors as Hisashi tries to hide her existence while she grapples with the basics of human interaction. She's powerful enough to level city blocks but helpless when it comes to operating a microwave. Their fragile arrangement teeters between disaster and something that might actually resemble a relationship. The tone swings wildly from slapstick humor to surprisingly sincere moments between two people from completely different worlds trying to understand each other. There's genuine chemistry beneath the chaos, even if neither of them sees it coming. If you want a lighthearted romance that doesn't take itself seriously but earns its emotional beats anyway, this one delivers exactly what it promises: two misfits figuring things out together.
