Idun
She is a spirit who happens to be in Nifleheim by chance. She met Nero when she was attacked by evil spirit and saved by him. After that she knew that she had not died yet. So she wanted to find the way to go back to her real world. Many things happen and she is the key changing fate of this world.

She is kind, calm and very optimistic. Being naive and trusts others without doubt is one of the reason she is beloved. She is also clumsy and easy to be distracted by cute things. Quite airhead sometime.

Since young she had very poor health. She could not do heavy things and had to stay in the hospital. Her only hobby was writing the novel. In that way she is one who knows how a life is worth. Her dream is to help as many as she can to gain dreams and happiness.

After she came to Nifleheim, she can do many things that she had always long for. She can run around outside. She can cook and do housework she loves as long as she wants. But still she needs to return to her real world.

Her unique ability is to heal any spirit instantly. And she had strong spirit power although she was just come to Nifleheim. It is because of her strong faith in her way of life. Her weapon is a magical pen which can cast any magic circle in a blink of time. Unfortunately she is a very slow learner and can perform only few magic.

Her hobby is to writing novel, bake some dessert and do housework. Helping people is her hobby too. But since she is very clumsy the troubles always happen after that.
