Goddess

The Goddess is the goddess that reincarnated Lugh Tuatha Dé into different world to have him kill the hero.

Appearance
The Goddess is pure white woman with white skin, eyes and clothes. She wears a chainlet on her hair with white flowers and a crystal on her forehead. She also wears multiple gold rings and bracelets.

Personality
The Goddess appear to have a cunning personality, but aside from that nothing much is known about her. She is not an ally of demons or humans. She only cares about the world itself.

Background
The Goddess welcomes the soul of the greatest assassin. She offers him to be bleached and reincarnated like he would normally do, or to be reincarnated in a different world with his memories intact. The man quickly realizes she wants him to kill someone and she reveals its the hero of that world. The Goddess explains that he will defeat the Demon King in sixteen years, but two years later he will use his power for selfish desires and send the world into chaos. She explains that a simple human couldn't kill him as the hero is special and how the skills, the magic and the world works. She then lets him choose his own skills, which she finds boring, but also interesting as if he had chosen skills anyone else would have chosen, he wouldn't stand a chance. When everything is ready, she reincarnates him as Lugh Tuatha Dé.

Trivia

 * Although it hasn't been mentioned yet, in the Anime OP, in the end, there was a scene where Lugh points his gun at the goddess, there was also several scenes in the manga where the goddess does some suspicious activities such as saying "start plan b" which might indicate that she will abandon Lugh for an unknown reason.
