When Daikichi's grandfather dies he leaves behind a young daughter named Rin. However, as most of the family is embarrassed at the idea of a 79-year-old man having a six-year-old child, they can't seem to figure out what to do with her. Disgusted by this behavior, Daikichi decides to take care of her himself, but he's a bachelor, has no idea how to raise a child, and isn't even all that comfortable with kids! Now, Daikichi must do the normal things a parent does such as enroll her in school, buy her clothing and teach her about the life and world around her. But more importantly, he must also help her deal with her father's death and decide whether or not she should try to find her mother. Together, the two begin their unlikely relationship as father and daughter, navigating each of life's bumps along the way.
I think that Usagi and Papa no Iu Koto o Kikinasai are basically the same story just the main character who is taking care of the one who has lost their parent is 19 and is going to college and is not taking care of one but three children. Because of the age difference from the Daikichi to Yuuta opens up a lot more problems for Yuuta and it gives a more of a comedy role than a serious one of Usagi. At any rate the animes are almost mirror images of themselves if not for the age difference of the main character and the comedy rather than the seriousness.
The two have the same basic premise, though Usagi Drop lacks the buffering comedy element that Papa no Iukoto has. So, if you liked Usagi Drop but it came on a bit strong, Papa no Iukoto will be right for you, while if you liked Papa no Iukoto but the comedy felt out of place, then Usagi Drop is right up your alley.
Raising children- is the common element shared by the both series with lot of love and affection. if you liked one then you can't miss another.
Both Papakiki and Usagi Drop are about a young man taking in a young girl/ young girls and overcoming the endeavors that come with it. While Papakiki has a more upbeat comedic taste, Usagi Drop has a more calm and mature flavor.
Similar stories, done in a different style, If you liked one chances are you will like the other.
Whenever Kippei is at school, he has one thing on his mind: girls. From skipping class to cheesy lines, he'll do anything it takes to reel the ladies in, though he never seems to find the right person. But the bachelor lifestyle is soon to change when young Yuzuyu enters the picture. This five-year-old cutie has been abandoned by her mother, and is to be taken care of by none other than Kippei! Unfortunately for the both of them, Kippei has no experience raising a child, so the learning curve will be quite steep...
If you enjoy PapaKiki or Aishiteru I believe you may enjoy the other. Both include young men taking in young female family members and watching over them; while trying to juggle thier own lives- IE. High School/College & Jobs and thier love lives. There are cute comedy and drama elements in both due to the main characters learning how to raise kids.
Both animes are about a young man taking care of a child/ children. In Papakiki, the protagonist takes in the girls and raises them alone with no support, while in Aishiteruze Baby, the protagonist is still in high school and raises the child with the support of his family,
Asu and Kyo are two orphaned sisters; their mother passed away some time ago, while their father abandoned them due to gambling issues. Asu and Kyo now live in a rundown apartment complex. Asu, the younger sister, is responsible for all of the housework while Kyo is in charge of living expenses; and together, the two sisters work hard to live a comfortable and enjoyable life. Looking to one another for support, Asu and Kyo experience the hardships of daily living, but are still able to welcome each day with a smile.
I think you'd like both shows, because they're both about family members caring for each other. In "Binbou Shimai Monogatari" there are just 2 sisters whose parents are gone where as in "Papa no lu Koto o Kikinasai!" there are 3 sisters and the uncle. But both animes feel similar, because one tends to sympathise with them and live with them through their every day life and the hardships they have to go through.
If you tend to have a strong protective instinct, both shows will grab you by this very special spot in your personality and drag you into a rollercoaster ride of emotions for sure.
