The main character Udagawa Gosuke has inherited his father's dojo, mainly because his father and elder brother were made to commit hara-kiri. He wasn't really supposed to get it simply because he's a second son.<br /><br />Due to the way his father and brother died, he doesn't have a whole lot of self confidence, so he practices fencing daily at a nearby dojo.<br /><br />However, because the people at that dojo are asses, he soon tries to invent a dojo and a style for people who just want to enjoy themselves.<br /><br />However, what really sets this aside from most shounen is that the male and female main characters are actually married.<br /><br />His wife, Udagawa Shino, is the younger sister of his senpai, and is a bit... weird, to say the least. She makes rabbit masks to help bring in a bit of money, although to say that she's obsessed with rabbits would be an understatement. She claims it's because "the rabbits will someday reach the moon."<br /><br />When Gosuke founds his new dojo, he decides to create a style of swordsmanship known as "Rabbit Style Fencing."
