[Kaioshin Sama]

Relationship dynamic in this sounds a lot like Accel Worlds (to name one example) what with it being the heroine that takes point and the male hero kind of riding her coattails until he comes into his own. It's a pretty uncommon one historically though not as much as some people might think and becoming far less so with each passing season. The heroine in these also almost always seems to follow the same basic rule of the tall dark and bishoujo ojou-sama archetype too making me think it's some sort of very specific wish fulfillment trend of the hapless everyday male student being rescued and looked after by the "untouchable" school beauty/idol/princess who would normally never have any reason to pay special attention to them that's taking off in Japan with each passing example. It's kind of hard not to notice as I pointed out in the last thread I created.
