Next up, a lesson in how not to make a romance series.

Keiichi Morisato is a college freshman who in an attempt to get takeout food, inadvertently calls the Goddess hotline which summons the Goddess Belldandy, thinking this is all a joke he makes the wish to have Belldandy stay with him, only for it to work.
Forced to move to a Buddhist temple, (because it's a male only dorm) Belldandy and Keiichi live out the series as a couple all the while Belldandy's sisters Urd and Skuld get drawn in to the temple as extra roommates all the while a force tries to separate Belldandy and Keiichi.
This OVA hasn't aged well and you can pin point a number of issues as to why this is the case.
Keiichi isn't a terrible protagonist when compared to others in the same position and a number of people would respond in the same way if their wish granter was Belldandy but apart from hobbies he's really dull.
And then there's Belldandy, the legendary 90s waifu and she's ten times worst. She has no personality beyond extreme kindness, she's like a Stepford wife, even when she is forced to fight she really doesn't do anything, finally her powers aren't clearly defined, yes a goddess can do anything but there has to be a guideline within their universe as to what these deities are capable of for world building and the OVA has no time to do this.
It would take over a decade to start from scratch with a TV series but the damage is kind of done. The story is weak, the characters are boring, only Urd and Skuld will get a laugh and the voice dub acting is weak but not terrible.
It's saving grace is the animation which is detailed and beautiful, something I wish they kept for the 00s tv series.
Final Verdict: It's a weak romance story who's only sin is failing to give it's characters a personality and Belldandy is basically the perfect waifu until you develop taste.
