Raskreia is the current leader of the Nobles and her soul weapon is Ragnarok. She is the daughter of the previous lord who entered the eternal sleep 500 years ago. Unlike her predecessor, she is more strict and conventional, showing an arrogant and sever attitude. However, according to Gejutel, she is too sentimental in her decisions and this is one of the reasons why she is considered unfit to be Lord by the so-called traitors. Rai and Frankenstein are acquainted with her, but they’re not on friendly terms. Before the previous Lord’s eternal sleep, some of the clan leaders made excuses and didn’t enter the eternal sleep with him. The previous Lord agreed with their request, but as soon as he entered the eternal sleep they betrayed him. Therefore Raskreia holds a grudge against the traitors and she claims that Rai was the one responsible for the betrayal against the former Lord. However after facing Rai and receiving his incomplete Ragnarok, she discovers that Rai has been asleep for 820 years. Rai’s arrival triggers a message from the previous Lord in which he explains he wanted his daughter to embrace freedom rather than carry the heavy burdens the Lord has to face. After hearing that, she has the feeling she doesn’t really deserve Rai’s Ragnarok, so she doesn’t accept it because she thinks she needs to earn it. This triggers a new message from the previous Lord in which he praises her because she made an important decision when not accepting Rai’s offer.
