The LS-tou Zone (エルエストウゾーン Eruesutou Zōn, lit. "Legend-Swords-Island Zone"?) is an area of the Digital World where special beings referred to as Legend-Arms inhabit. This country is exposed terrain for invading armies, but the Digimon living in the area are unable to properly defend it while in their natural shapes. As a result, they acquired the unique ability to turn their own bodies into gigantic, peerless weapons that can then be wielded by another Digimon, substantially increasing their might.
