Arcueid is a noblewoman with a long lineage of aristocracy. She had a strict upbringing and was told to never cut her hair because she had to be a dignified woman.

Most of her schooling was done from home and she knew little of the outside world.

She didn't have any time to learn more about herself. Her family's origins remain a mystery to her.


Sometimes she would sense the presence of something otherworldly but couldn't discern the cause.

Everyone told her she was just having a nightmare.

In the end, no one believed her claims that she heard or saw something unusual.

These strange occurrences kept happening until suddenly everything changed.

There was a betrayal in within her home causing mysterious men to show up. These men have an unknown origin and could be related to supernatural factions.

A strange letter showed up at her doorstep telling her to leave the mansion.

Arcueid then leaves everything behind and cuts her hair.

She moved to Kaisou and lived there for two months.


Arcueid is related to Ragna on his mother's side. She's a distant family friend.

Ragna's family has been dead for the past decade and they've been out of contact for a long time.

She doesn't know if Ragna is alive or not.

When they meet up in Kaisou she's surprised to find him still alive.

During her time in Kaisou, she befriended Ritsuka Fujimaru.

They occasionally spend time together and have a good relationship.
