Everything you say gets on my nerves. Then I'll let you experience it for yourself. And I'll make you kneel before me. I'll show you that I, Eastin, will be your ruler.
— Eastin talking to Ban after the Sins invaded the Timespace Junction.
Eastin is a young woman with light skin, long turquoise hair, pink eyes and wears a crown-like tiara. She appears to pad her chest on her more revealing outfits.
Eastin is a very arrogant and self-centred person, usually seeing herself as superior, underestimating her opponents and putting them down when they demonstrates some weakness. She's also a bit impatient, as she easily get annoyed with energetic people like Roxy and Valenty. Lilia also stated that Eastin is someone full of attitude.
Despite this, she already demonstrated that cares for her friends, visible in her concern with Valenty when the scientist let herself stay behind in order to distract Merlin while she and Mono invaded the Temporal Rift in order to rescue Lilia.
At her original world, she was the heiress and the next leader of a family of nobles called the 'Amabyllis family'. However, at some point of her life, people from her world, feared of her magical powers, attempted to kill her by throwing her at the ocean, however, she managed to survive the murder attempt and killed the people who tried to drown her, this event ended up living her title as the 'Ruler of Seas' and creating on the noblesse a desire to conquer the world and become the ruler of all.
Years later, Eastin was summoned to Britannia by Lilia with the magic crystal obtained by Valenty in Balleno. However, due to distortions on the space-time, the summoning wasn't properly completed and Eastin was teleported to the margins of a lake near to Balleno instead of Lilia and Valenty's location. There, the Ruler of Seas meets Ban, confusing him as one of her family's mine slaves.
Later, after reuniting with her future teammates, the noblesse agrees on helping Lilia and joins the Seven Disasters. Some time after Lilia gets caught by Merlin, Eastin and Valenty starts their plan to rescue her leader. During their mission, Eastin managed to summon a new ally that would help to cut through the space-time prison where Lilia was trapped, the Human Weapon Mono and, with her new ally's help, she's able to break into Lilia's prison. There, she and Mono are surprised by Ban and Gowther, who where waiting for Lilia's friends to ambush and capture them, however, Lilia suddenly escapes from Merlin and reunites with her teammates .Eastin, them unite her powers with Lilia and, together, manage to defeat both Sins and escape once again.
Despite Eastin underestimating Lilia's capacity as the leader of the group, they seems to work well together.
