Seina is a portly, middle-aged woman. Her hair is short and dirty blonde (brown in the manga), and she usually wears a dress and full apron while at work.
Seina is a matronly woman who acts like a mother to the Martillos: she scolds them for their apathy; looks after them when they are hurt; and is altogether fond of them despite their gangster status.
(To be added.)
- Previous fan readings of her name have included Sena or Senna. 'Seina' comes from the official Yen Press translation of The Rolling Bootlegs.
