Daikichi Kawachi is a 30-year-old bachelor working a respectable job but otherwise wandering aimlessly through life. When his grandfather suddenly passes away, he returns to the family home to pay his respects. Upon arriving at the house, he meets a mysterious young girl named Rin who, to Daikichi’s astonishment, is his grandfather's illegitimate daughter! The shy and unapproachable girl is deemed an embarrassment to the family, and finds herself ostracized by her father's relatives, all of them refusing to take care of her in the wake of his death. Daikichi, angered by their coldness toward Rin, announces that he will take her in—despite the fact that he is a young, single man with no prior childcare experience. Usagi Drop is the story of Daikichi's journey through fatherhood as he raises Rin with his gentle and affectionate nature, as well as an exploration of the warmth and interdependence that are at the heart of a happy, close-knit family.

As the head of her middle school's science club, it's only fitting that Ueno is also a brilliant inventor. With devices that can convert any liquid into drinkable water, deodorize the most foul smells, or even generate dark matter to be used as a means of concealment, it seems like nothing is beyond Ueno's capabilities. However, she doesn't invent these devices for the advancement of mankind. Rather, the one force that motivates her is love, the only phenomenon she can't quite figure out. Ueno is head over heels for Tanaka, her nonchalant fellow club member. Yet, because she is too nervous to confess her love and he is too oblivious to notice her affection, her love life is completely stagnant. In Ueno's mind, if she could just expose him to perverted situations, then surely he'd get flustered and fall for her, right? Assisted by her stone-faced classmate and dedicated wingwoman Yamashita, Ueno employs her many inventions on Tanaka in a lewd manner in hopes that he may one day understand how she feels.

As a young boy, Prince Oscar Lyeth Increatos Loz Farsas was cursed by the Witch of Silence, rendering it all but impossible for any woman to bear him a child. After 15 years of fruitlessly seeking a way to lift the spell, Oscar resorts to enlisting the help of a different witch. To this end, he heads to the Azure Tower, home of the Witch of the Azure Moon. Ascending the tower is no easy task; for decades, no one has overcome the array of traps, puzzles, and enemies designed to repulse any challengers. Oscar, however, easily climbs to the top, where he meets the fabled witch, Tinasha. To the prince's surprise, despite being hundreds of years old, Tinasha looks like a beautiful young woman in her late teens. Oscar explains his circumstances to the witch, who quickly perceives the true nature of his affliction. Though she claims that undoing the spell would be tremendously difficult, Tinasha proposes a workaround—to find Oscar a partner capable of withstanding the curse's effects. Realizing that such a woman is right in front of his eyes, Oscar boldly tells the witch to marry him. Though he is promptly rejected, the young prince refuses to back down, and the two eventually reach an agreement: Tinasha will leave the tower and live with Oscar for the next year. As the two continue searching for a way to lift Oscar's curse, word of Tinasha's emergence from isolation spreads, catching the attention of all sorts of old acquaintances.
