Personality
Helena was described as an honorable and determined woman, always trying to do her very personal best in the things she does like yearning to protect her villagers from every harms way possible when facing demons. Helena is really weak when it comes to dealing with children, becoming all innocent-like. Needless to say, she is also friendly and respective towards older peers around her. However, her true nature is that of a modest and docile young woman since Helena doesn't know how to approach or speak to a man properly as she tends to fidget every time.

However, she can be serious at times if the one she is talking to happens to be actually a demon, because she's really protective about herself including her chastity upon physical contact. This could be the reason why her first impression kept failing, with only inducing more hate from others due to a similar vibe share between her and the demon's influence, labeling her a witch. Helena easily resented loneliness and can't handle the hate on her own when after all, she is the one that doesn't want to be left all alone by everybody as no one ever try to reach out for her until Keith met her.

This allows Helena, essentially, "take over" the power (or the body, in her case, a Etherious) of an entity and use it to fight. It can increase the power, strength, and speed of the Caster, sometimes adding a new skill, such as flying, or swimming. One can only "take over" the power of beings that they truly "know". In addition to embodying an entity, Take Over can also be used to control another entity or another entity's abilities. However, it is unknown of the entity one takes control of/takes over the abilities of has to have the characteristics of the Caster's specific type of Take Over magic. Demon Superiority: Due to the nature of Helena's Take Over, she has the ability to dominate the will of a demon, effectively making them her own subordinates. Therefore, Helena can control demons and manipulate them to do her very bidding. While having omnipotence over the demons, Helena was able to cause them to explode at the same time in a similar fashion likewise to that of Mirajane's Satan Soul.

Depending on which incantation Helena chants, a different effect will be placed on the target, such as increased speed or stamina as well as the user can also enchant themselves. Unfortunately, she cannot heal targets, but only to relieve fatigue and exhaustion. However, after being revived, Helena has since lost this Magic and cannot then pray or preach about God as she now believed they've abandon the humans including her as mere tools to be use and discard as sacrifices.
