Frenda Seivelun is a member of the Academy City-based underground team called ITEM. She is one of the main combatants of the team, though not having any apparent esper ability of her own, she makes up for it with her incredible prowess in close-quarters combat, as well as expertise in traps and concealed weaponry. Her full name is revealed to be Frenda Seivelun, upon the introduction of her little sister by the name of Fremea Seivelun.

   She and ITEM's leader Mugino Shizuri have a sort of a master-servant relationship, with Frenda usually being scolded for her fits of unprofessionalism at work. Out of combat, she seems to enjoy talking about ordinary things girls her age would talk about; she also values her legs highly, saying that it is her pride as a woman.

    In battle, though, her moves can be difficult to read as her humorous remarks often serve as a diversion; this in turn, combined with her cunning style of combat, can prove to be a deadly combination. She is also somewhat vicious and possesses a blood-thirsty nature, indicating that she enjoys taking away the life of someone as if she was destined to end them.

    She has the habit of oftenly using the term "Kekkyoku," which can be translated as "Basically" or "In the end" in her speech. Her younger sister also has a similar trait.
