Shaula/Relationships

Flugel
As Flugel's apprentice, Shaula is absolutely loyal to Flugel and has never refused him once. Shaula has mentioned several times that she is in love with Flugel. Flugel in turn, was regularly exasperated at her antics, as she mentioned that he had said something similar when Subaru berated her.

Reid Astrea
Though their relationship from before Reid's demise remains shrouded in mystery, Arc 6 clearly showed Shaula's despise for the red haired man, calling him a "demon" and a "savage" seemingly due to Reid tending to fondle her breasts. Upon lying eyes on him, she froze stiff and fainted. Reid also didn't commentate much about her, which suggests they weren't all-too close back in the day. It should also be worth mentioning that Shaula stated she was able to make him use both hands to grip his sword every ten strikes, when the two fought back in the day.

Natsuki Subaru
As Shaula is horrible at telling people apart, she refers to people based on smell alone. Due to Subaru apparently having Flugel's scent, she believes him to be her master. She went as far as to keep the fifth rule of the Pleiades Watchtower (being allowed to destroy the trials) hidden from the Emilia Camp to spend more time to Subaru, showing her immense attachment to him.

Meili Portroute
During Meili's stay at the Pleiades Watchtower, Meili becomes attached to Shaula, who she refers to as "naked onee-san". Typically, she spends her time hanging onto Shaula's shoulder. While Shaula did think positively of her, she displayed little to no grief of learning the fact that she was murdered, stating that she only cares about Subaru.

Daphne
The author revealed that Shaula is a Demon Beast created by Daphne. This would mean Daphne is the mother Shaula was referring to so often. She repeatedly showed love and respect towards her and her Master.
