Forest is a Leymon who immigrated to the small country of Senshivia (センシビア Senshibia?) following a disastrous event at the capital city of Janna, where and his Leymon comrades were met with hostility despite their attempt to negotiate with humans. He joins Caius Qualls in his quest to help save the country from danger and knows a lot about the geography of the world, so he serves as a traveling guide. He may seem intimidating due to his stature, but is a kind person. During the story, he returns to his home village of Sansa after 14 years away.
