Fenrir

She is the leader of the Warden squad and always be by side of her empress, Lady Hel, as personal bodyguard.  Her job is to discipline the reapers as well as the magistrate job. She earns the respect and adore by the reapers despite of her emotionless personality.

Fenrir is a perfect warrior in battle. No one can beat her in strength. She assists Hel while working and she train the new reapers how to fight. She is very strict and serious. Her manner is above formal to anyone. She can do all maid work too but she is really, really bad cook. She has slow response and often breaks things too.

Her silver hair and maid uniform is very stand out from the other reaper. She has unique aura around her. She adores Hel a lot and her loyalty is second to none. No one know her past except Loki who brought her here.

Her ability is the physical power of her body. She can easily pick up a huge rock with her single hand. Her weapon is always in her sleeve. They are the unbreakable chains, Gleipnir. These chains can be control as she wants and can be extended as far as she can see. With the incredible power and weapon she can bind any enemy or capture who she wants.   

She has weakness on cute things and can be lost control. So she usually prohibits the cute things in her sight except in her own room. Her hobby is to do knitting as well as training fighting.
