Elsa has long black hair tied into one tail on the left side along with eyes that droop, giving her a gentle aura. She wears a black dress and wields bent black swords from the northern lands.
Elsa is a battle maniac, not even hesitating to injure herself if she can fight strong opponents, which is helped by her abnormal healing rate. This is also shown through her persistence. Due to her blessing she claims to be a vampire, though she doesn't drink blood, nor does she receive any ill effects when under the sun. Her favorite things are seeing colorful bowels and touching warm looking internal organs. Within combat, she enjoys cleaving through the abdominal region with the intent of tearing the target's bowels out.
Elsa also enjoys knitting cotton dolls, especially after a good kill, and mentions to have over 10 years of experience. Although it isn't mentioned, she presumably destroys them later.
Elsa once lived in Gusteko, she was an orphan and a thief, who was caught stealing by a seller, she almost got raped, until Elsa grabbed a piece of glass and opened her assailant's stomach. Over the years she became a well-known Assassin and sometime later started working for the Assassin Organization.
One day, on Mama's orders, she went to greet Meili, who was living with the Demon Beasts as a feral child in a forest, killed all the Demon Beasts and brought her back. At that time, Meili was in a state where she couldn't speak, so her manner of speech and such were greatly influences by Elsa.
Skilled Assassin: Elsa is skilled as an assassin, being able to overwhelm opponents such as Rom and Frederica. However, she was unable to assassinate Cecilus, and according to Meili she would be unable to kill "Mama".
Equipment: Elsa wields kukri knives and throwing knives which she uses in combat. She keeps spares inside of her clothes in case she needs them.
Blessing (祝福): Elsa refers to her immortality as blessing, though it is officially called curse doll (呪い人形). It is a curse which involves the user carving a curse mark that includes the information of the target they want to kill on someone, and upon activation, the person with the curse mark gains immortality, but as a cost they lose their sense of self and can't do anything else but kill the target and they die when the target is killed. Also, there seems to be a limit on the immortality. However, there's supposedly a way to cast the curse without the person losing their sense of self, which is what happened to Elsa, though repeatedly dying turned her into a curse doll. People who become curse dolls are mistakenly referred to as vampires due to a curse doll once drinking blood in an attempt to die.
- In her web novel character introduction, Elsa is stated to have a Divine Protection, though this is likely to be an oversight as the author confirmed she doesn't have one.
- According to the author, Elsa's birthday is April 29, a pun on death and meat.
