Saikano

Saikano: The Last Love Song on This Little Planet. (最終兵器彼女), also known as She, the Ultimate Weapon, is a Japanese manga series written and illustrated by Shin Takahashi. It was serialized in Shogakukan's seinen manga magazine Weekly Big Comic Spirits from December 1999 to October 2001, with its chapters collected in seven tankōbon volumes.

A 13-episode anime television series adaptation by Gonzo aired from July to September 2002. A two-episode side-story original video animation (OVA) by Studio Fantasia was released in 2005. A live-action film adaptation premiered in January 2006.

Both the manga and the anime series were licensed for English release in North America by Viz Media. The anime was later licensed in 2014 by Sentai Filmworks and released under the title She, the Ultimate Weapon.

Plot
The story begins with Shuji, a high school student in a Hokkaidō coastal city, walking up to an observatory and reminiscing about his girlfriend, Chise; there he finds her exchange diaries that she purposefully left behind. The ensuing story is narrated by Shuji through flashbacks while reading Chise's diary. Chise, a fellow student in his class, declares her love for Shuji at the beginning of the series. However, Chise is very shy and Shuji is insensitive: neither know how to express their feelings very well, but they do indeed have feelings for each other.

One day, while Shuji is shopping in Sapporo, unknown bombers attack the city in broad daylight. He and his friends run for cover, but notice a fast and small flying object shooting down the enemy bombers. Separated from his friends, Shuji wanders through the wreckage—only to stumble upon Chise; here she has metal wings and weapons—apparently grafted onto her body. She tells him she has become the ultimate weapon, without her knowledge or consent, and that she is seen by the Japan Self-Defense Forces (JSDF) as the last hope for defending Japan. In the anime, it is not apparent why Chise was chosen to be the ultimate weapon or why the country is under attack. It was not until the OVA episodes were released that an explanation for Chise being chosen was offered: her body has the highest degree of compatibility with the weapon system.

This story focuses primarily on Chise's fading humanity as her condition worsens. The main conflict is within Chise herself; she questions whether or not she is human. Her soul is constantly trying to be a normal girl, while her body succumbs to the devastating effects of the weapon cell within her. Fundamentally important to the plot is the relationship between Shuji and Chise. From this, the resolution of the conflict follows. In the end, she is able to realize who she truly is.

A number of minor characters who do not necessarily know of Chise's role in the war have sub-plots that concern everyday people in the context of war: a woman whose husband is constantly away from home, a school boy who joins the army to protect his girlfriend, a girl whose civilian boyfriend is killed in a bombing, and others.

Characters

 * Chise (ちせ)
 * A shy, clumsy girl with very little self-esteem and has poor grades in everything except for World History. She was constantly hospitalized in Tokyo during her elementary years, and thus, has very few friends (except for Akemi). She starts dating Shuji, with Akemi's help, and tries to make her relationship work with him despite his apparently aloof personality. However, Chise is very inexperienced and does not know much about relationships to the point she reads shōjo manga for advice. She was turned into the ultimate weapon against her will and the series revolves around her and her fading humanity. As Chise's weapon-side starts to take over, her heart stops beating, her body lacks warmth and her sense of taste and touch are dulled, but other senses (especially sight) are accentuated. Her condition worsens and her humanity seems to fade away entirely. In the final episodes of the anime, she appears to be nothing more than a cold, ruthless machine that delights in her growing, destructive powers and killing people without mercy. Her love for Shuji is the last of her humanity. Throughout the story, she tries to come to terms with her body while still trying to convince herself that she is still human. She believes that she is nothing more than a weapon designed to kill. Her boyfriend Shuji, however, is able to help her break free by showing her that she is able to protect the ones she loves, and that only a human can experience the feeling of love. This helps Chise destroy the body in which she was trapped, and she realizes that she is indeed human. This brings to question what is meant by the term "ultimate weapon" used throughout the story. Chise's soul had been the only thing that was able to destroy her body, which was claimed to be the most powerful thing in the world.

 * Shuji (シュウジ)
 * A somewhat antisocial 17-year-old high school student who gets higher than average grades and used to be on his school's track team.

He is the only civilian who knows Chise is the ultimate weapon and promises that he will never divulge her secret. Shuji is feeling constantly guilty and useless because his irresponsible actions tend to hurt Chise. Later on in the series, he comes to accept his love for Chise and vows to protect her and be by her side at all costs.
