# Kokoro Library

Kokoro Library (ココロ図書館, Kokoro Toshokan) is a slice-of-life Japanese manga series by Nobuyuki Takagi and Yōsuke Kuroda, originally serialized between April 2000 and July 2002 in Monthly Comic Dengeki Daioh. It follows the peaceful daily lives of three sisters who live in a library.
The manga was adapted into a 13-episode anime television series directed by Koji Masunari, who is also known as the director of the anime OVA series Read or Die (2001) and Kamichu! (2005). It is described by critics as a prime example of the iyashikei or "healing type" anime genre.

## Plot

Kokoro Library is a heartwarming slice of life series depicting the peaceful everyday lives of three orphaned sisters as they take care of the library which also serves as their family home. The anime delves more deeply into the library's history, its connection to the local town, and challenges faced by the sisters.
Kokoro, the youngest, has just joined her sisters Aruto and Iina as an official librarian. The library receives few visitors, and each visit is often the subject of an entire episode. Kokoro learns the meaning of being a librarian, meets her favourite author, and takes a family trip to the seaside. The library is called "the place where miracles happen", although we see nothing more magical than Kokoro's ability to produce rainbows with her watering can.
Events take a dramatic twist when phantom thief Funny Tortoise steals a mysterious locked book which belonged to Kokoro's father, who died when she was very young. Worse, the town mayor announces that the library will be closed due to lack of visitors. Kokoro is heartbroken, but believes the answer may lie in the stolen book, which has meanwhile been returned to the library.
The next episode is seen from the point of view of a young soldier named Sant Jordi, during a war which has seen the town heavily bombed. Jordi's positive attitude makes an impression on his comrades, who occupy a ruined library. When the town is approached by an enemy armored division, Jordi's decision to destroy the bridge without killing the enemy ultimately saves the town. He begins to distribute library books to the townsfolk to lift their spirits in the difficult post-war period, ultimately settling in the town and constructing Kokoro Library.
Kokoro, reading the story in what is revealed to be her father's diary of the war, finally has a connection to the parents she never knew. The sisters head to town hall to show the diary to the mayor, hoping to change her mind. They arrive to discover a massive protest against the library's shutdown—the people of the town have not forgotten Jordi's contributions. The mayor allows the library to remain open, and Kokoro and her sisters continue to live their peaceful days together in the library.

## Production

Yōsuke Kuroda, a scriptwriter who had highly appreciated Takagi's doujin works published under the name "Boo", heard from Takagi himself that he was going to retire from his company and train to become a manga artist. "It's too late to train to become a manga artist now when you have the ability," he said, and pitched Takagi to the editor-in-chief of Monthly Comic Dengeki Daioh, whom he knew.
The editor also appreciated Boo's drawing style and immediately gave him a positive response for serialization. At that time, Kuroda was instructed to write a scenario, which he accepted, and the serialization took shape. According to Kuroda, it took only an hour and a half from the time he was informed of Takagi's resignation to the time he informed Takagi that the serialization had been decided. As a result, Kuroda was in charge of the script for both the original story and the animation.
Kokoro Library was animated digitally, rather than on cels as had been used for Studio Deen's animated productions until the late 1990s. However, limited-edition hand-painted replica cels were made available to collectors for ¥5,000 by online sale.
The setting of Kokoro Library is ambiguous. The town is identified in signage as "Toaru City" (都亜瑠), a homonym for the phrase "a certain city", although it is never named in dialogue. We are never explicitly told the name of the country where the library is situated, or the year when the series takes place. Rather, it is a pastiche of Japanese and European cultural elements. Several pieces of mid-20th century technology appear: Iina drives a redecorated World War II Volkswagen Schwimmwagen, while other characters drive the post-war Citroën H Van and Citroën DS. In episode 11, Jordi's side carry the Karabiner 98k used by German troops in World War II, while the enemy armored unit fields the Russian T-34 and GAZ-67; however, neither side's nation is explicitly identified. Modern computers and cameras also appear, along with science fiction androids.
The anime was notable as Chiwa Saitō's first major voice acting role. Saitō would go on to perform over three hundred anime voice roles in the following two decades.
Kokoro and the comparoid June make appearances in Nobuyuki Takagi's 2003 manga Pure Marionation, set eight years after Kokoro Library.

| Kokoro and her sisters come to terms with the library's pending closure. A talking bunny appears to Kokoro one night, claiming she has watched over Kokoro from the moon, from where her parents watch over her too. She is inspired to take the diary to the town, believing the mayor will change her mind if she reads it. The sisters are aided on their way by people whose lives they have touched—the delivery driver Uezawa, the bikers who helped Kokoro on her first visit to the town, and the thief Funny Tortoise. At the town hall, Kokoro finds that large crowd has amassed to protest the library's closure, and the mayor declares that due to public demand the library will remain open. The following spring, Kokoro delivers a copy of Himemiya Kirin's latest book: Kokoro Library, a story about a library where miracles happen. Kokoro continues to live her peaceful days with her sisters in the library. |||

## Reception

Kokoro Library's anime adaptation was met to generally positive reviews. The first DVD volume was reviewed by Paul Grisham of Mania.com, where he praised the use of color, saying, "Colors are rich and warm and convey the fairy tale setting of the Kokoro Library and the nearby town effectively." Paul also commented on the audio, calling it "warm and inviting without even the slightest hint of distortion." Jeremy A Beard from THEM Anime Reviews praised the "general pleasant feeling and atmosphere" of the small town depicted in the anime. Despite finding the "overall Kokoro Library experience enjoyable", Jeremy remarked that its "accompanying relaxed pacing" would turn viewers off.
