"One bright autumn day, I learned of Grandpa's demise. Hence I took a leave of absence, packed my bag, and rushed home. Only to find a little girl I had never seen before."
When Daikichi Kawachi questions his mother, he learns that the six-year-old girl is Rin, his grandfather's illegitimate daughter. When everybody else in the family makes excuses to avoid taking care of her, Daikichi gets pissed off and impulsively takes her in himself.Bunny Drop (Usagi Drop in Japanese) is a manga by Yumi Unita centering on the drama of bachelor Daikichi and the change he makes to his life so he can care for Rin. From buying her clothes, getting her into kindergarten, transferring to a job with better hours, and trying to work out what to do regarding Rin's absentee mother Masako, Daikichi does all in his power to do right by Rin, no matter the cost to himself.The series is licensed by Yen Press, which has started releasing it in North America. An anime (viewable on Hulu) ran in the noitaminA block in the Summer 2011 Anime Season, and a live-action movie was released in July of that year.
Canon Discontinuity: The anime implies that Daikichi will have a relationship with Kouki's mother, and only covers the events of manga volumes 1-4. This may have been deliberate, considering that the events that happen from volume five onwards are considered to be very distasteful.
Continuity Nod - After the Time Skip, Rin still has in her room the desk that they bought when she entered elementary school.
Cuteness Proximity - Several adults are afflicted by this around Rin. Rin herself seems to like kids younger than herself and babies.
Death Is a Sad Thing - Rin's understanding of Gramps' death, and a fear of her own death that results.
Defrosting Ice Queen: Daikichi's mother wants nothing to do with Rin at first. However, when Daikichi brings her back for a family visit, she begins warming up to the girl to the point where she asks Daikichi and Rin to visit her again.
Delayed Reaction: When Daikichi takes Rin shopping for some clothes, he asks how some she doesn't get a skirt. She mentions that skirts aren't allowed at nursery school. He agrees with her for a moment, then it hits him that he needs to register her for school.
Emotionless Girl - Deconstructed: Rin acts like this around people she's afraid of or doesn't trust (most everyone to begin with), and some of Daikichi's relatives cite it as a reason why they won't take her in. We soon find out that Rin is anything but.
Evolving Credits - in the anime, the ending sequence changes slightly to match the content of the episode during the first section and also in the colored pencil/chalk pastel drawing of Rin towards the end
From the Mouths of Babes: In episode 7, Reina and Rin talk about Haruko and Daikichi's marital status. They say that Haruko would be better off being single, while Daikichi would be better off married, without fully comprehending the situations the adults are in.
Funny Background Event: A few in the anime, one of them involves Rin playing on her new futon while Daikichi is on the phone
Hot Dad - The father of Sayaka (a classmate of Rin's), who is a former model. Remarked upon in-universe.
Identical Grandson - Daikichi looks so much like a young version of his grandfather that some relatives at the grandfather's wake thought Daikichi was a ghost. This is also why Rin initially becomes attached to him.
Is That Cute Kid Yours? - Daikichi gets this a couple times. He has no idea initially how to handle it, since "No, she's my aunt" is not something you want to go around saying.
Last Disrespects: Many of the family members attending Souichi's funeral are shocked to learn that he recently had an illegitimate child, Rin, shortly before his death. Her presence at the funeral isn't particularly welcomed and they mostly ignore her. When the time comes for the family to talk about what to do with her, shortly after the actual funeral proceedings, the discussion quickly devolves into an outlet for expressing their anger toward the situation and talking about how odd they find Rin and her dubious origins.
Ma'am Shock: Male version — her first morning with Daikichi, Rin calls him "oji-san," which shocks him as much because he's just 30 as because she's his Oba San in the blood relationship sense. (The official translation obscures the joke by rendering these as "mister" and "ma'am".)
In Daikichi's case, it's pretty obvious early on; while he does have the best of intentions, he's very much out of his depth. While some of it is overboard, there's good reason for his mom to regularly take him to task about child-rearing. In short, while there's no doubt that Daikichi cares and tries to do the right thing, actually getting his act together to do so is a process.
Even as he gets better at being a father, other people still remark upon the oddness of the fact that, say, Rin does a significantly larger portion of the cooking than you would normally anticipate a seven-year-old to be doing
Masako is a much straighter example. She's described by Daikichi's grandfather as simply not being mature enough to be a mother yet. Given from what we've seen of her on-screen this is unfortunately very, very true.
May-December Romance - Daikichi's grandpa and Masako. Rin later on at the end with Daikichi, who is older than her by 24 years.
Meaningful Echo - In the first volume, Daikichi notes that he would be lying if he didn't call raising Rin a sacrifice, but hopes that he can say it in the future. At the end of the fourth (a little over a year after taking Rin in), he says that it's not one.
Meaningful Name - In Japanese, the bellflower is called the rindou. On seeing Rin pick bellflowers for her father's grave, Daikichi realizes his grandfather named her after his favorite flower.
Missing Mom - A plot point is Daikichi learning the identity of Rin's mother and confronting her.
Not What It Looks Like - When Daikichi takes his cousin Haruko shopping in episode 7, they run into Yuriko. When he sees them, he panics, then immediately tells the latter that the woman with him is merely his cousin on his mother's side. Haruko teases him a bit about it afterwards.
Orphan's Plot Trinket - Rin's baby book. Gives us the first clue about Rin's mother and is the hiding place of Daikichi's grandfather's will.
Parental Abandonment - Rin; father dead, mother's whereabouts unknown. Once mother's whereabouts discovered, mother still wants nothing to do with her because she's irresponsible.
Parental Incest - Despite being Daikichi's aunt, Rin was raised by Daikichi from childhood and is younger than the former by more than two decades. Eventually, Daikichi learns that the two are Not Blood Related. Rin learns it much later.
Potty Failure - Rin's bedwetting in chapter 4 and episode 3 of the anime; partly stress, partly scared to enter the bathroom alone at night.
Reverse Cerebus Syndrome - The story starts out as an innocent, but serious and realistic in terms of character personality, tale about parenting and loving an adopted child. After the timeskip it becomes a FanserviceyWife Husbandry story, with teenage Rin dating Kouki, then marrying Daikichi, the man who is, for all intents and purposes, her father.
Sand in My Eyes - When Daikichi gets teary-eyed about Rin's feelings for him, he claims it's sweat.
Sick Episode - Rin gets sick in episode 10. Fortunately for a worried Daikichi, Yuriko stops by to visit them and help him take care of Rin.
