Ever since Rakurou "Sunraku" Hizutome started to play the extremely popular virtual reality game Shangri-La Frontier, he has truly fallen in love with it. Sunraku has quickly made a big name for himself by fighting two of the seven unique, nearly unbeatable monsters, which is unthinkable for most players. To progress the game's story, he sets out on an adventure with his leporine guide, Emul, to acquire a magic operation unit from an ancient workshop. Though Sunraku breezes through this quest alongside his clanmates Towa "Arthur Pencilgon" Amane and Kei "OiKatzo" Uomi, there seems to be an ulterior motive as to why the two of them decided to help Sunraku in the first place. Nevertheless, Sunraku gains valuable knowledge and allies, critical for his advancement in the game. By seeking out powerful enemies and unraveling the inner workings of the game's world, Sunraku may just change Shangri-La Frontier forever.

While spending the summer at his aunt's house, the young but sickly Shou makes an amazing discovery: after following the house cat into the bushes, he gets a glimpse of a miniature girl about the size of his finger! Calling her kind "Borrowers," as they survive on tiny bits of human possessions, the girl introduces herself as Arrietty. As he discovers that she lives in the house basement with her parents, Pod and Homily, Shou becomes imaginably excited at the idea of such unique neighbors.

However, he fails to understand the adversities they face on a daily basis. In addition to keeping their existence hidden, they must also embark on perilous adventures into human territory, from the house to the outdoors, in order to make a living. Despite her parents' warnings, Arrietty befriends Shou, stirring up unexpected events that may change their lives forever.

Delighting the eye and conquering the heart, the breath-taking story of a friendship transcending the tensions between two different human kinds begins.
