Monster Hunter Orage (Japanese: モンスターハンター オラージュ, Hepburn: Monsutā Hantā Orāju) is a Japanese manga series written and illustrated by Hiro Mashima.

Loosely based on the Monster Hunter series of video games by Capcom, Monster Hunter Orage premiered in Kodansha's shōnen manga magazine Monthly Shōnen Rival in April 2008.

A few years after Greylee's death, which was due to a gunpowder incident, he returns to his master's residence, Akamaaya Town, to join the guild there.

In that guild, he meets a girl called Ailee and after a series of events, he finds that she is the daughter of his master.

From this point onwards, they form a party to find the legendary Myo Galuna, which was Greylee's lifelong ambition.
