Natalia (twin sister)
Sonia (ソニア, sonia) was a twilight working for Paulklee Guild. She is twins with Natalia.
Sonia always has a calm, almost fed up expression on her face. She has large, half-closed eyes of light hue and long eyelashes. She has the same short haircut like her twin's but messier. Sonia wears a similar choker of made of black ribbon and a teardrop brooch as Gina Paulklee. She wears similar attire to her sister, except in a different style. Her attire consists of a black shirt tucked into Paulklee Guild shorts.
Sonia and Natalia's personalities contrast each other Sonia is extremely reserved and has not said anything in the manga yet. She is serious and very focused on tasks appointed to her - unlike her twin who gets too excited that she leaves herself vulnerable at times, only to be saved by Sonia.
Sonia and her sister work as a pair to fight their opponents. She is seen to be more agile than her sister. Sonia's weapon of choice is a large machete. She, however, has been shown to be weaker than her twin at combat.
