Goddess

The Goddess or Venus 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. Depending on the occupations of the previous souls, the Goddress has wore numerous outfits based on them.

Personality
The Goddess appear to have a cunning personality, but aside from that nothing much is known about her. She is neither an ally of demons or humans. She only cares about the world itself and doesn’t care about what the reincarnated soul does to achieve their goal, giving them full autonomy. However, because she gave them unmonitored independence, it only left her in immense disappointment whenever her subjects fail.

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.

History
So far, the Goddess hasn't appeared often in the story after reincarnating Lugh in this new world with the aim of preventing the destruction of the world by the hero. Nonetheless, that doesn't stop her from observing what is going on and acting from time to time, such as appearing in a dream to Tarte when she was young or communicating with Lugh and the bishop and highest ranking priestess of the country, Aram Karla.

Abilities
The goddess has many powers, being responsible for this world. She has the power to welcome souls, to bleach and reincarnate them in her world while being able to leave them their memories intact or not. As seen with Lugh, she also possesses the power to bestow them unique skills and communicate directly with them once reincarnated in the New World.

 * As she hired many men and possible women from military background to fight the brave in Promise Day, most of them are ended up slacking their abilities and their life judging by the crystal of future time much to her disappointment and dismay until she saw Lugh potential after she reincarnated him to the Tuatha Dé noble family, so she decided to manipulated every character in her world to have a fate meeting with Lugh such as Tarte and Maha for the Promise Day.
