Eris

Tammy Lynetta (タミー・リネッタ Tamī Rinetta) is a member of D.O.O.M. She appears to have some sort of history with Kaguya Yoru.

Personality
Generally Tammy behaves like an innocent, bubbly yet naïve schoolgirl that is always smiling and giggling. She never seems to act any other way even when killing her "prey" or expressing other emotions such as anger or confusion. She seems to have an obsession with Kaguya.

However beneath this demure persona lies a dark and twisted psychopath.

Trivia

 * The characters physical appearance is based off of Tamamo no Mae from the "Fate" series.
