Nash is a young boy who lives in Pannam Town. He can be found outside Chain's home during the day. He will tease Mag about the Launcher family debt and his comments change as the debt gets repaid. He is attracted to Linear and frequently invites her to leave the Launcher home and marry him. He wants to one day become an adventurer and explore the ruins in the future.
When Linear is kidnapped by The Eighth Empire, Nash assumes that Linear either left Mag or he sold her to pay off his debt.
