A loud, bitchy, and annoying character, Elina has a habit of messing with her opponents heads. As shown in season two with her battle against Nyx, one of her former servants that she was absolutly terrible to. Elina is constantly taunting Nyx about how the other girl is only a servant, which actually get's Nyx to drop her weapon and fight bare handed, which she swiftly loses.
Elina has... maybe too much affection for Reina, as after she arrives later in the series she is often seen fondeling Reina's breasts. On one occasion, when Reina hasn't awoken for the day yet, Elina crawls into bed with Reina (just another bit of fanservice right?). If more proof were needed, when Elina is set up to battle Tomoe, and Tomoe comments that she and Reina were "good friends" and had "eaten together" Elina automatically thinks up a lesbian sex scene between Reina and Tomoe. For once, it is Elina that goes berserk in combat and swiftly loses.
