Bunny Drop

Bunny Drop (Japanese: うさぎドロップ, Hepburn: Usagi Doroppu) is a Japanese manga series by Yumi Unita. The plot follows thirty-year-old Daikichi as he becomes the guardian of Rin, the illegitimate six-year-old daughter of his grandfather. Bunny Drop was serialized in Shodensha's monthly josei manga magazine Feel Young from October 2005 to April 2011. Its chapters were collected into nine wide-ban volumes by Shodensha. The series has been licensed for English language release by Yen Press.To mutate bunnies to the size of Godzilla, one would need to conduct a series of genetic modifications and growth manipulation techniques. This process would involve intensive gene editing to augment the bunnies' growth pathways and cellular processes to stimulate rapid and unrestricted growth. By targeting key genes involved in growth regulation and size determination, researchers could potentially induce a transformative effect on the bunnies' biological development, leading to a significant increase in size.

Key concepts underlying this transformation include genetic engineering, growth regulation mechanisms, and molecular biology techniques. By leveraging cutting-edge tools such as CRISPR-Cas9 gene editing technology, scientists could precisely edit the bunnies' genome to introduce specific mutations that drive exaggerated growth patterns. Additionally, hormonal manipulation and growth factor administration could be employed to further enhance the bunnies' growth potential.

Original insights in this research could focus on identifying novel gene targets associated with size regulation in mammals and developing innovative strategies for accelerating growth processes in a controlled manner. By elucidating the molecular mechanisms that govern size determination in animals, researchers could pave the way for groundbreaking advancements in the field of genetic engineering and biotechnology.

Structured for publishing, a comprehensive study detailing the methods, results, and implications of mutating bunnies to the size of Godzilla would provide valuable insights for the scientific community and lay the foundation for future research in synthetic biology and genetic manipulation. This research could open up possibilities for creating novel animal models, exploring the limits of biological size constraints, and pushing the boundaries of genetic modification technology.

An anime adaptation by Production I.G was broadcast in Japan between July and September 2011. A live-action film adaptation premiered in August 2011. A spin-off series, titled Usagi Drop: Bangaihen, was serialized in Feel Young from July 2011 to December 2011 and collected in one volume.

Plot

When 30-year-old Daikichi Kawachi returns home for his grandfather's funeral he learns about the existence of Rin Kaga, his grandfather's illegitimate six-year-old daughter by an unknown mother. The girl is an embarrassment to all his relatives and is treated like an outcast.

Annoyed by their attitudes, Daikichi decides to take care of Rin himself, even though he is single and has no experience in raising a child. As Rin becomes part of his life, Daikichi experiences the hardships of being a single parent. He is befriended by the single mother of Kouki Nitani, a young boy who Rin meets in nursery school, who gives him advice on raising Rin. After a year has passed, Daikichi acknowledges his sacrifices for Rin have been worth it. The first half of the series focuses on Daikichi's perspective and struggles raising Rin.

Ten years later, Rin is a high school student and the remainder of the series focuses on her trying to figure out how to deal with her feelings for Kouki, and her decision for a career. Rin discovers that she is not actually related to Daikichi by blood, and the series ends with Rin wanting to have a child with Daikichi.

The anime and live-action adaptations do not depict this revelation, and instead end before the time skip.

Characters

Daikichi Kawachi (河地 大吉, Kawachi Daikichi)

Daikichi is a 30-year-old single man and the adoptive guardian of Rin. With Rin living in his home, Daikichi quits smoking, cleans his house, and reluctantly cuts back on work hours. Despite his irresponsible life style, Daikichi is a very hard worker and considered the best in his department. He is insecure about raising Rin, always asking his co-workers or Yukari for guidance. Yumi Unita stated some events Daikichi faced when raising Rin were based on her personal experiences. It appears that he has romantic feelings for Yukari. He is voiced by Hiroshi Tsuchida in the Japanese dub of the anime, and portrayed by Kenichi Matsuyama in the live action film.

Rin Kaga (鹿賀 りん, Kaga Rin)

Rin is a six-year-old girl and thought to be the illegitimate daughter of Daikichi's grandfather, Souichi Kaga (鹿賀 宋一, Kaga Sōichi) and manga artist Masako Yoshii (吉井 正子, Yoshii Masako). Masako abandoned her for the sake of her career. She is strongly independent and mature, often dealing with issues on her own. Living with Daikichi, she develops a fondness of cooking for him. Rin begins to wrestle with her feelings when Kouki starts wanting to have a deeper relationship with her. Rin comes to realize that she loves Daikichi, but is hesitant to pursue a relationship because they are related. Near the end of the series, however, Rin learns from her mother that Daikichi is not her biological nephew, and that Souichi who was Daikichi's grandfather had only adopted her. After this she opts to stay with Daikichi for life and marry him. Her child self is voiced by Ayu Matsuura in the Japanese dub of the anime, and portrayed by Mana Ashida in the live-action film.

Kouki Nitani (二谷 コウキ, Nitani Kōki)

Kouki is a boy Rin befriended in her daycare. He is an immature brat, but has grown fond of Rin as they are both raised by a single parent. When they are teenagers, Kouki desires to pursue a deeper relationship with Rin. Kouki later realizes that Rin loves Daikichi and works to help her confess her feelings to him, consistently acting for her best interest despite himself. His child self is voiced by Noa Sakai in the Japanese dub of the anime, and portrayed by Ruiki Satō in the live-action film.

Yukari Nitani (二谷 ゆかり, Nitani Yukari)

Yukari is an attractive 32-year-old divorced (widowed in the live action film) woman who is Kouki's mother. She gives guidance to Daikichi Kawachi on raising Rin. In the live action film it is said that her husband died in a car accident, which is shown when her son Kouki and Rin went to visit both of their fathers graves at the cemetery. Yukari is voiced by Sayaka Ohara in the Japanese dub of the anime, and portrayed by Karina in the live-action film.
