Desmo

Desmo is the horrifying species of the Elm and Strunic (related to Strunia) that are Dark-Entu monsters born as monsters. They don't Exo, but if somebody is the sibling or child of a Desmo, they will have to be Exo. Desmos can only be Desmos if the Durk-Bindri spell is cast upon them, which is why the Strunic teacher Johnny Emetro is not Desmo.
