Beyond the Beyond (その向こうの向こう側, Sono Mukō no Mukōgawa) is a Japanese manga series written and illustrated by Yoshitomo Watanabe.

The series first premiered in Japan in the monthly shōnen magazine Comic Blade in 2004, where it ran until February 2008.

As he's walking home from school one day, a strange girl, named Kiara, falls from the sky, calling Futaba her master.

While under the bridge, Futaba's cell phone rings and Kiara borrows it and drops it into the river, opening a mysterious portal.

Futaba learns that Kiara is actually not human but a flower called the "Amaranthine", and is much sought after because she has incredible powers that can only be activated by her master.

His older brother released him from his cell with a message from his mother: "If you find the Amaranthine and bring it to me, you can both live."
