Web, Arania

Arania Web is a Mage of the Mermaid Heel Guild and a member of its team competing in the Grand Magic Games. Arania, true to her spider theme, has been shown capable of generating spider webs from her body. These, much like their real counterparts, appear to be sticky, something which makes it possible for Arania to entangle foes with them. (Source: Fairy Tail Wikia)
