- When Hel was being herself, she can be seen with chin-height black hair, with red eyes. As for the clothes, she uses a red hat that has a golden emblem, a black cape with a red color underside, a red suit, and long black tight leggings with boots. When she is fighting and using her ability, her eyes will glow red.
- See as Alicia
- See as Nagisa Natsunagi
In the later part of the story, Hel is revealed to be created from Nagisa Natsunagi after Alicia's death "six years ago".
Beside abnormal physical abilities, Hel also had eyes that could glow bright red and 'mind control' bodies with the owners being irresistible. This power was then used by Nagisa Natsunagi in the battle against the <<Assassin>> Fubi Kase but due to Fubi's will, the power couldn't stop her totally.
Hel is a female being in Norse mythology who is said to preside over an underworld realm of the same name, where she receives a portion of the dead.
