Quina was a stowaway on the Passenger-ship Lombardia.
After the ship sank she landed on the Isle of Seiren and was eventually taken as hostage by Kiergaard.
She was used as bait in a Trap which killed Captain Barbaros who shielded her with his body.
This led to her being eternally grateful for his saving her life. She spent much time praying at his Grave and taking care of it.
Aside from this she also worked often as Lookout at the Watchtower of Castaway Village.
During a talk with Adol she said that she owed her life to not only Captain Barbaros but also others. For them she would always do her best to smile and live a good happy Life.
