Saikano: The Last Love Song on This Little Planet. (最終兵器彼女, Saishū Heiki Kanojo, lit. She, the Ultimate Weapon) is a Japanese manga series by Shin Takahashi, creator of Iihito and Kimi no Kakera. Saikano was originally serialized in Shogakukan's Big Comic Spirits magazine.

A live-action movie adaptation was released in Japan on January 28, 2006 with Aki Maeda starring as Chise.

The Saikano manga has been licensed and distributed by Viz Media in English in North America. The anime series is distributed in the UK by Manga Entertainment (as "She, the Ultimate Weapon"). The anime series was also licensed by Viz, but is now licensed by Sentai Filmworks.

The story begins with Shuji (シュウジ, Shūji), a high school student in a Hokkaidō coastal city, walking up to an observatory and reminiscing about his girlfriend, Chise (ちせ); 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.
